Child psychiatry and human development 2024年9月9日The Parent Overprotection Measure (POM) is a promising scale to measure parent overprotection toward a child from the parent's perspective. However, no Japanese translation of the scale has been developed, and whether the POM can be applied to a Japanese population is unknown. This study translated the POM into Japanese and examined its psychometric properties. Parents of 380 children aged 4 to 7 years (including 190 mothers and 190 fathers) completed online questionnaires. Exploratory and confirmatory factor analyses (CFA) indicated that the Japanese translation of the POM has a bi-factor structure, including one general factor (general overprotection) and two specific factors (care/attention and control/prevention). The measurement invariance of reports from mothers' and fathers' perspectives was confirmed by multiple group CFA. The McDonald's Omega was acceptable for all factors, but the general overprotection factor explained most scale variance. Pearson's correlation coefficients were more than .20 between the control/prevention factor and child anxiety symptoms in both mother and father reports. The correlation between the control/prevention factor and parent anxiety according to fathers' reports also exceeded .20. These results provided the factor structure and supported the reliability of the POM among a Japanese population; however, further investigation of the validity of the scale is needed.

Brain connectivity 2024年8月13日BACKGROUND: Generalized anxiety disorder (GAD) and social anxiety disorder (SAD) are distinguished by whether anxiety is limited to social situations. However, reports on the differences in brain functional networks between GAD and SAD are few. Our objective is to understand the pathogenesis of GAD and SAD by examining the differences in resting brain function between patients with GAD and SAD and healthy controls (HCs). METHODS: This study included 21 patients with SAD, 17 patients with GAD, and 30 HCs. Participants underwent psychological assessments and resting-state functional magnetic resonance imaging (rsfMRI). Whole-brain analyses were performed to compare resting-state functional connectivity (rsFC) among the groups. Additionally, logistic regression analysis was conducted on the rsFC to identify significant differences between GAD and SAD. RESULTS: Patients with SAD and GAD had significantly higher rsFC between the bilateral postcentral gyri and bilateral amygdalae/thalami than HCs. Compared with patients with SAD, those with GAD had significantly higher rsFC between the right nucleus accumbens and bilateral thalami and between the left nucleus accumbens and right thalamus. RsFC between the left nucleus accumbens and right thalamus positively correlated with state anxiety in patients with SAD and GAD, respectively. In addition, logistic regression analysis revealed that the right nucleus accumbens and the right thalamus connectivity could distinguish SAD from GAD. CONCLUSIONS: GAD and SAD were distinguished by the right nucleus accumbens and the right thalamus connectivity. Our findings offer insights into the disease-specific neural basis of SAD and GAD.

Journal of affective disorders 2024年7月12日BACKGROUND: Studies comparing the brain functions of major depressive disorder (MDD) and social anxiety disorder (SAD) at the regional and network levels remain scarce. This study aimed to elucidate their pathogenesis using neuroimaging techniques and explore biomarkers that can differentiate these disorders. METHODS: Resting-state fMRI data were collected from 48 patients with MDD, 41 patients with SAD, and 82 healthy controls. Differences in the amplitude of low-frequency fluctuations (ALFF) among the three groups were examined to identify regions showing abnormal regional spontaneous activity. A seed-based functional connectivity (FC) analysis was conducted using ALFF results as seeds and different connections were identified between regions showing abnormal local spontaneous activity and other regions. The correlation between abnormal brain function and clinical symptoms was analyzed. RESULTS: Patients with MDD and SAD exhibited similar abnormal ALFF and FC in several brain regions; notably, FC between the right superior frontal gyrus (SFG) and the right posterior supramarginal gyrus (pSMG) in patients with SAD was negatively correlated with depressive symptoms. Furthermore, patients with MDD showed higher ALFF in the right SFG than HCs and those with SAD. LIMITATION: Potential effects of medications, comorbidities, and data type could not be ignored. CONCLUSION: MDD and SAD showed common and distinct aberrant brain function patterns at the regional and network levels. At the regional level, we found that the ALFF in the right SFG was different between patients with MDD and those with SAD. At the network level, we did not find any differences between these disorders.

BMJ open 14(6) e081205 2024年6月25日INTRODUCTION: Insomnia is a common health problem and cognitive-behavioural therapy (CBT) is recommended as a treatment. As there is a critical shortage of CBT-trained therapists, we developed a digital CBT application (IIIP MED: Sleepy Med) as Software as a Medical Device for insomnia. This paper describes the study protocol for an exploratory randomised controlled trial (RCT) to evaluate effectiveness and safety of our developed digital CBT (dCBT) for 5 weeks compared with zolpidem tartrate for patients with insomnia disorder. METHODS AND ANALYSIS: This proposed multicentre exploratory RCT will be conducted at the outpatient clinic of Chiba University Hospital, Akita University Hospital and Yoyogi Sleep Disorder Center, Japan. The study population comprises two parallel groups (dCBT and zolpidem) consisting of 15 participants each (n=30 in total) diagnosed with insomnia disorder who remain symptomatic at 4 weeks after sleep hygiene education. We will evaluate the effectiveness at baseline, week 5 (post-intervention) and week 10 (follow-up). The primary outcome will be the change of subjective sleep onset latency at week 5 from baseline. Secondary outcomes include sleep-related outcomes, such as objective sleep onset latency measured by mobile electroencephalography, functional improvement during the daytime and quality of life. ETHICS AND DISSEMINATION: Ethics approval was granted by the Institutional Review Board of Chiba University Hospital (K2023001). All participants will be required to provide written informed consent. Results will be published in international journals. TRIAL REGISTRATION NUMBER: jRCT2032230353.

Psychological medicine 1-14 2024年3月19日BACKGROUND: Previous research on the changes in resting-state functional connectivity (rsFC) in anorexia nervosa (AN) has been limited by an insufficient sample size, which reduced the reliability of the results and made it difficult to set the whole brain as regions of interest (ROIs). METHODS: We analyzed functional magnetic resonance imaging data from 114 female AN patients and 135 healthy controls (HC) and obtained self-reported psychological scales, including eating disorder examination questionnaire 6.0. One hundred sixty-four cortical, subcortical, cerebellar, and network parcellation regions were considered as ROIs. We calculated the ROI-to-ROI rsFCs and performed group comparisons. RESULTS: Compared to HC, AN patients showed 12 stronger rsFCs mainly in regions containing dorsolateral prefrontal cortex (DLPFC), and 33 weaker rsFCs primarily in regions containing cerebellum, within temporal lobe, between posterior fusiform cortex and lateral part of visual network, and between anterior cingulate cortex (ACC) and thalamus (p < 0.01, false discovery rate [FDR] correction). Comparisons between AN subtypes showed that there were stronger rsFCs between right lingual gyrus and right supracalcarine cortex and between left temporal occipital fusiform cortex and medial part of visual network in the restricting type compared to the binge/purging type (p < 0.01, FDR correction). CONCLUSION: Stronger rsFCs in regions containing mainly DLPFC, and weaker rsFCs in regions containing primarily cerebellum, within temporal lobe, between posterior fusiform cortex and lateral part of visual network, and between ACC and thalamus, may represent categorical diagnostic markers discriminating AN patients from HC.

BioPsychoSocial medicine 18(1) 5-5 2024年2月21日BACKGROUND: Feeding and eating disorders are severe mental disorders that gravely affect patients' lives. In particular, patients with anorexia nervosa (AN) or bulimia nervosa (BN) appear to have poor social cognition. Many studies have shown the relationship between poor social cognition and brain responses in AN. However, few studies have examined the relationship between social cognition and BN. Therefore, we examined which brain regions impact the ability for social cognition in patients with BN. METHODS: We used task-based functional magnetic resonance imaging (fMRI) to examine brain responses during a social cognition task and the Reading Mind in the Eyes Test (RMET). During the fMRI, 22 women with BN and 22 healthy women (HW) took the RMET. Participants also completed the eating disorder clinical measures Bulimic Investigatory Test, Edinburgh (BITE) and Eating Disorders Examination Questionnaire (EDE-Q), the Patient Health Questionnaire (PHQ-9) measure of depression; and the Generalized Anxiety Disorder (GAD-7) measure of anxiety. RESULTS: No difference was observed in the RMET scores between women with BN and HW. Both groups showed activation in brain regions specific to social cognition. During the task, no differences were shown between the groups in the BOLD signal (p < 0.05, familywise error corrected for multiple comparisons). However, there was a tendency of more robust activation in the right angular gyrus, ventral diencephalon, thalamus proper, temporal pole, and middle temporal gyrus in BN (p < 0.001, uncorrected for multiple comparisons). Moreover, HW showed a positive correlation between RMET scores and the activation of two regions: medial prefrontal cortex (mPFC) and anterior cingulate cortex (ACC); however, no significant correlation was observed in women with BN. CONCLUSIONS: While activation in the mPFC and ACC positively correlated to the RMET scores in HW, no correlation was observed in BN patients. Therefore, women with BN might display modulated neural processing when thinking of others' mental states. Further examination is needed to investigate neural processing in BN patients to better understand their social cognition abilities. TRIAL REGISTRATION: UMIN, UMIN000010220.

Molecular Psychiatry 2024年2月7日Abstract White matter pathways, typically studied with diffusion tensor imaging (DTI), have been implicated in the neurobiology of obsessive-compulsive disorder (OCD). However, due to limited sample sizes and the predominance of single-site studies, the generalizability of OCD classification based on diffusion white matter estimates remains unclear. Here, we tested classification accuracy using the largest OCD DTI dataset to date, involving 1336 adult participants (690 OCD patients and 646 healthy controls) and 317 pediatric participants (175 OCD patients and 142 healthy controls) from 18 international sites within the ENIGMA OCD Working Group. We used an automatic machine learning pipeline (with feature engineering and selection, and model optimization) and examined the cross-site generalizability of the OCD classification models using leave-one-site-out cross-validation. Our models showed low-to-moderate accuracy in classifying (1) “OCD vs. healthy controls” (Adults, receiver operator characteristic-area under the curve = 57.19 ± 3.47 in the replication set; Children, 59.8 ± 7.39), (2) “unmedicated OCD vs. healthy controls” (Adults, 62.67 ± 3.84; Children, 48.51 ± 10.14), and (3) “medicated OCD vs. unmedicated OCD” (Adults, 76.72 ± 3.97; Children, 72.45 ± 8.87). There was significant site variability in model performance (cross-validated ROC AUC ranges 51.6–79.1 in adults; 35.9–63.2 in children). Machine learning interpretation showed that diffusivity measures of the corpus callosum, internal capsule, and posterior thalamic radiation contributed to the classification of OCD from HC. The classification performance appeared greater than the model trained on grey matter morphometry in the prior ENIGMA OCD study (our study includes subsamples from the morphometry study). Taken together, this study points to the meaningful multivariate patterns of white matter features relevant to the neurobiology of OCD, but with low-to-moderate classification accuracy. The OCD classification performance may be constrained by site variability and medication effects on the white matter integrity, indicating room for improvement for future research.

Molecular Autism 15(1) 2024年1月4日Abstract Background To examine the relationship between social camouflage and mental health in Japanese autistic adults and make an international comparison with a sample from the UK. Methods This study analysed secondary data of participants with a self-reported diagnosis of autism from Japan (N = 210; 123 men and 87 women) and the UK (N = 305; 181 women, 104, men, and 18 nonbinary). The relationships between the quadratic term of the Camouflaging Autistic Traits Questionnaire and mental health scales, including depression and anxiety, were assessed. Results The UK sample showed linear relationships, whereas the Japanese sample showed significant nonlinear relationships. The quadratic terms of the Camouflaging Autistic Traits Questionnaire slightly explained generalised anxiety (β = .168, p = .007), depression (β = .121, p = .045), and well-being (β = − .127, p = .028). However, they did not explain the association between social anxiety and the Camouflaging Autistic Traits Questionnaire. Limitations Participants had self-reported diagnoses, and while the autism-spectrum quotient provides a cut-off value for screening, it does not enable confirming diagnoses. Mean scores of the Japanese version of the Camouflaging Autistic Traits Questionnaire were lower as compared to the original CAT-Q, which implies that the social camouflage strategy types used by autistic people in Japan and the UK could differ. The cross-sectional design limits causal inferences. Conclusion In the UK, more social camouflage was associated with poorer mental health scores, whereas too little or too much social camouflage was associated with a low mental health score in Japan. The Japanese population is seemingly less aware of and educated on autistic characteristics and considers ‘average’ behaviour a good thing. This could influence Japanese autistic people’s social camouflage use, differing from that of autistic people in the UK. The differences in the relationship between social camouflage and mental health between Japan and the UK could be associated with national-level divergence regarding the culture of autism.

Frontiers in neuroscience 18 1449673-1449673 2024年Hedgehog signaling is a highly conserved pathway that plays pivotal roles in morphogenesis, tumorigenesis, osteogenesis, and wound healing. Previous investigations in patients with Gorlin syndrome found low harm avoidance traits, and increased volumes in the cerebrum, cerebellum, and cerebral ventricles, suggesting the association between brain morphology and the constitutive hyperactivation of hedgehog signaling, while the changes of regional brain volumes in upregulated hedgehog signaling pathway remains unclear so far. Herein, we investigated comprehensive brain regional volumes using quantitative structural brain MRI, and identified increased volumes of amygdala, striatum, and pallidum on the global segmentation, and increased volumes of the lateral and medial parts of the central nucleus of the amygdala on the detail segmentation in Ptch heterozygous deletion mice. Our data may enhance comprehension of the association between brain morphogenic changes and hyperactivity in hedgehog signaling.

Work (Reading, Mass.) 77(2) 573-587 2024年BACKGROUND: Emergency service workers have highly stressful occupations; the stressors encountered can contribute to the development of mental disorders such as depression, anxiety, and posttraumatic stress disorder (PTSD). OBJECTIVE: The present study used a conceptual model and survey to identify variables influencing the association between probable PTSD and quality of life (QOL) in emergency service workers. METHOD: PTSD was assessed using the Impact of Event Scale-Revised. QOL was assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey. Path analysis was used to determine whether stress-coping (Brief Coping Orientation to Problems Experienced [Brief COPE] scores), social support (Multidimensional Scale of Perceived Social Support [MSPSS] scores), and resilience (Connor-Davidson Resilience Scale scores) explain the association between probable PTSD and QOL among 220 emergency service workers in Japan. RESULTS: Impact of Event Scale-Revised scores were significantly positively associated with Brief COPE Active coping scores and significantly negatively associated with MSPSS scores. Brief COPE Active coping and MSPSS scores were significantly positively associated with Connor-Davidson Resilience Scale scores, which were in turn significantly positively associated with Medical Outcomes Study 36-Item Short-Form Health Survey scores. CONCLUSION: Active coping in response to stressful situations is important for maintaining good mental health among emergency service workers. Active coping and social support may strengthen resilience, and resilience may improve QOL. Screening for mental health and QOL should include simultaneous assessment of stress-coping, social support, and resilience. Although the findings of this cross-sectional study are important, it could not confirm a causal relationship between PTSD and QOL.

BMC psychiatry 23(1) 681-681 2023年9月19日OBJECTIVE: This study aimed to measure the level of psychological injury caused by work-related stress as well as the severity of depression among workers. METHOD: First, we conducted an online survey and recruited 500 workers diagnosed with depression or adjustment disorder to investigate what type of stress they experienced within six months before onset. Second, we conducted another online survey and recruited 767 participants who experienced some form of work-related stress. All the participants were classified into four groups by whether or not they were diagnosed with depression and whether or not they quit their jobs due to work-related stress. We used the Impact of Event Scale-Revised (IES-R) to measure psychological injury caused by work-related stressful events and the Patient Health Questionnaire (PHQ)-9 to assess the severity of depression. RESULTS: In study 1, 62.4% of workers diagnosed with depression or adjustment disorder experienced work-related stress within six months before onset. In study 2, the IES-R mean scores were 40.7 (SD = 23.1) for Group A (workers with depression and quit their jobs) and 36.67 (SD = 23.4) for Group B (workers with depression but stayed at their jobs), with both exceeding the cut-off point (24/25) of PTSD (Post-Traumatic Stress Disorder), while the mean score of Group C (workers who did not have depression but quit their jobs because of work-related stress) was 20.74 (SD = 21.2), and it was 13.89 (SD = 17.4) for Group D (workers who had work-related stress but stayed at their jobs), with both of them below the cut-off point of PTSD. The total scores of IES-R of Group A and Group B were significantly higher than those of Group C and Group D(p < 0.001). There was a significant positive correlation between the scores of IES-R and PHQ-9 for all four groups (r = 0.708). CONCLUSIONS: This study suggests that it is necessary to measure not only depressive symptoms but also the level of psychological injury resulting from stressful events in the workplace to assess workers with depression.

2023年9月18日<p>Background: Imagery rescripting (IR) is a technique used in cognitive-behavioral therapy and schema therapy, the treatment process of which has not been empirically verified despite being implemented for various mental disorders. This study aims to examine the experiential process of patients who undergo IR.Methods: Schema therapy sessions were video-recorded with the consent of five patients with chronic depression. Two raters adopted the task analysis protocol to analyze the videos of seven IR sessions.Results: The following experiential process common among successful sessions with the patients was revealed: (1) recalling the episode of an adverse childhood experience, (2) expressing anger and dissatisfaction with the behavior of others during the adverse experience, (3) expressing needs that were not met during the adverse experience, (4) expressing hurt feelings due to needs that were not met during the adverse experience, (5) expressing complex emotions due to fulfillment of needs, and (6) having a sense of relief, attachment, or self-compassion. The behavioral markers of each step were identified as well.</p>

Psychiatry and Clinical Neurosciences Reports 2(3) 2023年9月18日Abstract Aim The spread of the novel coronavirus infection (coronavirus disease 2019 [COVID‐19]) has caused behavioral changes and mental illness in patients and their attendants during its early phase. The present study aimed to examine the association between precautionary behaviors against COVID‐19 and psychosocial factors in outpatients with pre‐existing disease and their attendants. Methods We conducted a cross‐sectional paper‐based questionnaire survey in Chiba University Hospital on 1019 patients and 513 attendants, and a web‐based questionnaire survey in Japan on 3981 individuals from the general population. We evaluated the participants' anxiety about COVID‐19, depression, health anxiety, and precautionary behaviors. Results Regarding knowledge and anxiety about COVID‐19, the protective factors for the high precautionary behaviors group were knowledge of COVID‐19 (odds ratio [OR] = 1.178, 95% confidence interval [CI]: 1.099–1.263), anxiety about the spread of COVID‐19 (OR = 1.348, 95% CI: 1.243–1.461), and anxiety about infecting someone with COVID‐19 (OR = 1.135, 95% CI: 1.039–0.239). Regarding psychosocial factors, the protective factors for the high precautionary behaviors group were patients (OR = 1.759, 95% CI: 1.056–2.929), their attendants (OR = 3.892, 95% CI: 1.416–10.700), health anxiety (OR = 2.005, 95% CI: 1.451–2.772), and nondepression states (OR = 1.368, 95% CI: 1.004–1.864). Conclusion Our findings suggest that patients and their attendants may perform high precautionary behaviors. Health anxiety and nondepression states may be associated with high precautionary behaviors.

BMJ open 13(9) e069734 2023年9月11日INTRODUCTION: Cognitive behavioural therapy for psychosis (CBTp) has demonstrated effectiveness in reducing positive symptoms, improving depression, enhancing coping skills and increasing awareness of illness. However, compared with cognitive behavioural therapy for depression and anxiety, the spread of CBTp in clinical practice is minimal. The present study designed a randomised controlled trial (RCT) research protocol to evaluate whether real-time remote video-conference CBTp (vCBTp) could facilitate access to psychosocial interventions and effectively improve symptoms compared with usual care (UC) for patients with schizophrenia. METHODS AND ANALYSIS: This exploratory RCT will consist of two parallel groups (vCBTp+UC and UC alone) of 12 participants (n=24) diagnosed with schizophrenia, schizoaffective disorder or paranoid disorder, who remain symptomatic following pharmacotherapy. Seven 50-min weekly vCBTp interventions will be administered to test efficacy. The primary outcome will be the positive and negative syndrome scale score at week 8. The secondary outcome will be the Beck Cognitive Insight Scale to assess insight, the Patient Health Questionnaire-9 to assess depression, the Generalised Anxiety Disorder-7 to assess anxiety, the 5-level EuroQol 5-dimensional questionnaire to assess quality of life and the Impact of Event Scale-Revised to assess subjective distress about a specific stressful life event. We will take all measurements at 0 weeks (baseline) and at 8 weeks (post-intervention), and apply intention-to-treat analysis. ETHICS AND DISSEMINATION: We will conduct this study in the outpatient department of Cognitive Behavioral Therapy Center at Chiba University Hospital. Further, all participants will be informed of the study and will be asked to sign consent forms. We will report according to the Consolidated Standards of Reporting Trials. TRIAL REGISTRATION NUMBER: UMIN000043396.

BMC psychiatry 23(1) 661-661 2023年9月7日BACKGROUND: Autistic people demonstrate focused interests, sensitivity to sensory stimulation, and, compared with the general population, differences in social communication and interaction. We examined whether a combination of the Awareness and Care for My Autistic Traits (ACAT) program and treatment-as-usual is more effective than only treatment-as-usual in increasing the understanding of autistic attributes, reducing treatment stigma, and improving mental health and social adaptation among autistic adolescents and their parents/guardians. METHODS: Forty-nine adolescents and their parents/guardians were randomly assigned to either a combination of ACAT and treatment-as-usual or only treatment-as-usual. The combined group received six weekly 100-minute ACAT sessions, while the treatment-as-usual group received no additional intervention. The primary outcome was the change in understanding of autistic attributes (Autism Knowledge Quiz-Child), administered from pre- to post-intervention. The secondary outcomes included the change in Autism Knowledge Quiz-Parent, reduced treatment stigma, and improved mental health and social adaptation among autistic adolescents and their parents/guardians. A primary outcome measure scale was scored by assessors who were blind to the group assignment. RESULTS: The combined group (both autistic adolescents and their parents/guardians) showed an increase in Autism Knowledge Quiz scores compared to those in the treatment-as-usual group. Autistic adolescents in the combined group also demonstrated a decrease in treatment-related stigma and an improvement in general mental health compared to those in the treatment-as-usual group, while there were no group differences in the change in social adaptation. For parents/guardians, there were no group differences in the change in treatment-related stigma, general mental health, adaptive skills, or attitudes toward their children. CONCLUSIONS: The ACAT program could be an effective treatment modality to increase the understanding of autistic attributes among both autistic adolescents and their parents/guardians. The ACAT program positively affects self-understanding, reduces treatment stigma, and stabilizes behavioral issues for autistic adolescents as a part of mental health measures, but it does not effectively reduce treatment barriers or improve mental health for parents/guardians. Further research should consider whether additional support for parents/guardians could be beneficial. TRIAL REGISTRATION: The study was registered in UMIN (UMIN000029851, 06/01/2018).

BMC psychiatry 23(1) 657-657 2023年9月6日The purposes of the current study are two-fold. Study 1 aimed to examine the psychometric properties of the Spence Children's Anxiety Scale (SCAS) in a Taiwanese sample. Study 2 aimed to explore the immediate and follow-up effects of Journey of the Brave Counseling Program (JBCP) on children's' anxiety, well-being, and life adjustment. A review and suggestions were provided for future research and practitioners in educational and counseling fields as reference. In Study 1, the pilot study included 150 to 200 children between ages 11 and 12 in Taoyuan City. In Study 2, we conducted a pretest-posttest nonequivalent groups quasi-experimental design. The participants in this stage were 16 children in an elementary school in Taoyuan City, between ages 11 and 12. After obtaining consent forms from the participants' guardians, we randomly assigned these participants to an experimental group (N = 8) and a control group (N = 8). The experimental group received a 40-minute JBCP session weekly for ten weeks. The control group received a 40-minute career exploration small group counseling weekly for ten weeks. We administered the SCAS, Psychological Well-Being Scale, and School Life Adjustment Scale in the pretest, posttest, and follow-up test to measure change of anxiety, well-being, and life adjustment of the participants. In addition, the current study implemented some qualitative data, such as group progress notes, group member feedback questionnaires, and semi-structured interviews with participants' homeroom teachers as supplementary data to clarify the effects of the JBCP. In Study 1, we found that the SCAS had a good validity and reliability for Taiwanese children. The results of Study 2 indicated that the JBCP had immediate and follow-up effects on the separation anxiety in the experimental group. With the pretest impact eliminated, the immediate and follow-up effects on overall anxiety in the experimental group were better than those on the control group. However, even though the immediate and follow-up effects of the JBCP on the experimental group were better than the control group but were not significant. Besides, the group member feedback questionnaires and participants' homeroom teachers all indicated that the experimental group participants had positive attitude toward the JBCP, and they also positively improved their emotions and interpersonal relationships with others.

Medicine 102(27) e34253 2023年7月7日Cognitive behavioral therapy (CBT) is known to improve chronic pain management. However, past studies revealed only small to moderate benefits in short-term results, and long-term follow-up studies are lacking. This study aimed to follow an integrated CBT program's effectiveness 1.5 years after its completion. This observational study was the follow-up on the data collected from our CBT sessions conducted under 3 different studies in 2018 to 2019. Seven assessment items (Numerical Rating Scale, Pain Catastrophizing Scale [PCS], Pain Disability Assessment Scale [PDAS], Patient Health Questionnaire-9 items, Generalized Anxiety Disorder 7, European quality of life 5-dimensions 5-level, and Beck Depression Inventory [BDI]) were statistically analyzed. Thematic analysis was conducted in semi structured interviews. PCS ( F = 6.52, P = .003), PDAS ( F = 5.68, P = .01), European quality of life 5-dimensions 5-level ( F = 3.82, P = .03), and BDI ( F = 4.61, P = .01) exhibited significant changes ( P < .05), confirmed by pairwise t test, revealing a moderate to large effect size. From post-treatment to follow-up, all scores showed no significant changes ( P > .1). In the qualitative study, the analysis revealed 3 subthemes: "Autonomy," "Understanding of yourself and pain," and "Acceptance of pain." Our study suggests that integrated CBT may reduce the scores of PCS, PDAS and BDI, and this effect lasts for at least 1 year. Identified themes support the relevance of mitigative factors in managing chronic pain.

Psychiatry and Clinical Neurosciences Reports 2(3) 2023年6月28日Abstract Aim Clinicians face difficulties in making treatment decisions for unspecified anxiety disorder due to the absence of any treatment guidelines. The objective of this study was to investigate how familiar and how often primary care physicians use pharmacological and nonpharmacological approaches to manage the disorder. Methods A survey was conducted among 117 primary care physicians in Japan who were asked to assess the familiarity of using each treatment option for unspecified anxiety disorder on a binary response scale (0 = “unfamiliar,” 1 = “familiar”) and the frequency on a nine‐point Likert scale (1 = “never used,” 9 = “frequently used”). Results While several benzodiazepine anxiolytics were familiar to primary care physicians, the frequencies of prescribing them, including alprazolam (4.6 ± 2.6), ethyl loflazepate (3.6 ± 2.4), and clotiazepam (3.5 ± 2.3), were low. In contrast, certain nonpharmacological options, including lifestyle changes (5.4 ± 2.3), coping strategies (5.1 ± 2.7), and psychoeducation for anxiety (5.1 ± 2.7), were more commonly utilized, but to a modest extent. When a benzodiazepine anxiolytic drug failed to be effective, primary care physicians selected the following management strategies to a relatively high degree: differential diagnosis (6.4 ± 2.4), referral to a specialist hospital (5.9 ± 2.5), lifestyle changes (5.2 ± 2.5), and switching to selective serotonin reuptake inhibitor (5.1 ± 2.4). Conclusion Primary care physicians exercise caution when prescribing benzodiazepine anxiolytics for unspecified anxiety disorder. Nonpharmacological interventions and switching to SSRI are modestly employed as primary treatment options and alternatives to benzodiazepine anxiolytics. To ensure the safe and effective treatment of unspecified anxiety disorder in primary care, more information should be provided from field experts.

BMJ Open 13(6) e070157-e070157 2023年6月23日Introduction Neuroimaging studies on attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) have demonstrated differences in extensive brain structure, activity and network. However, there remains heterogeneity and inconsistency across these findings, presumably because of the diversity of the disorders themselves, small sample sizes, and site and parameter differences in MRI scanners, and their overall pathogenesis remains unclear. To address these gaps in the literature, we will apply the travelling-subject approach to correct site differences in MRI scanners and clarify brain structure and network characteristics of children with ADHD and ASD using large samples collected in a multi-centre collaboration. In addition, we will investigate the relationship between these characteristics and genetic, epigenetic, biochemical markers, and behavioural and psychological measures. Methods and analysis We will collect resting-state functional MRI (fMRI) and T1-weighted and diffusion-weighted MRI data from 15 healthy adults as travelling subjects and 300 children (ADHD, n=100; ASD, n=100; and typical development, n=100) with multi-dimensional assessments. We will also apply data from more than 1000 samples acquired in our previous neuroimaging studies on ADHD and ASD. Ethics and dissemination The study protocol has been approved by the Research Ethics Committee of the University of Fukui Hospital (approval no: 20220601). Our study findings will be submitted to scientific peer-reviewed journals and conferences.

Neuropsychopharmacology reports 43(2) 188-194 2023年6月AIMS: Treatment guidelines with respect to unspecified anxiety disorder have not been published. The aim of this study was to develop a consensus among field experts on the management of unspecified anxiety disorder. METHODS: Experts were asked to evaluate treatment choices based on eight clinical questions concerning unspecified anxiety disorder using a nine-point Likert scale (1 = "disagree" to 9 = "agree"). According to the responses from 119 experts, the choices were categorized into first-, second-, and third-line recommendations. RESULTS: Benzodiazepine anxiolytic use was not categorized as a first-line recommendation for the primary treatment of unspecified anxiety disorder, whereas multiple nonpharmacological treatment strategies, including coping strategies (7.9 ± 1.4), psychoeducation for anxiety (7.9 ± 1.4), lifestyle changes (7.8 ± 1.5), and relaxation techniques (7.4 ± 1.8), were categorized as first-line recommendations. Various treatment strategies were categorized as first-line recommendations when a benzodiazepine anxiolytic drug did not improve anxiety symptoms, that is, differential diagnosis (8.2 ± 1.4), psychoeducation for anxiety (8.0 ± 1.5), coping strategies (7.8 ± 1.5), lifestyle changes (7.8 ± 1.5), relaxation techniques (7.2 ± 1.9), and switching to selective serotonin reuptake inhibitors (SSRIs) (7.0 ± 1.8). These strategies were also highly endorsed when tapering the dosage of or discontinuing benzodiazepine anxiolytic drugs. There was no first-line recommendation regarding excusable reasons for continuing benzodiazepine anxiolytics. CONCLUSIONS: The field experts recommend that benzodiazepine anxiolytics should not be used as a first-line option for patients with unspecified anxiety disorder. Instead, several nonpharmacological interventions and switching to SSRIs were endorsed for the primary treatment of unspecified anxiety disorder and as alternatives to benzodiazepine anxiolytics.

Molecular psychiatry 2023年5月2日Current knowledge about functional connectivity in obsessive-compulsive disorder (OCD) is based on small-scale studies, limiting the generalizability of results. Moreover, the majority of studies have focused only on predefined regions or functional networks rather than connectivity throughout the entire brain. Here, we investigated differences in resting-state functional connectivity between OCD patients and healthy controls (HC) using mega-analysis of data from 1024 OCD patients and 1028 HC from 28 independent samples of the ENIGMA-OCD consortium. We assessed group differences in whole-brain functional connectivity at both the regional and network level, and investigated whether functional connectivity could serve as biomarker to identify patient status at the individual level using machine learning analysis. The mega-analyses revealed widespread abnormalities in functional connectivity in OCD, with global hypo-connectivity (Cohen's d: -0.27 to -0.13) and few hyper-connections, mainly with the thalamus (Cohen's d: 0.19 to 0.22). Most hypo-connections were located within the sensorimotor network and no fronto-striatal abnormalities were found. Overall, classification performances were poor, with area-under-the-receiver-operating-characteristic curve (AUC) scores ranging between 0.567 and 0.673, with better classification for medicated (AUC = 0.702) than unmedicated (AUC = 0.608) patients versus healthy controls. These findings provide partial support for existing pathophysiological models of OCD and highlight the important role of the sensorimotor network in OCD. However, resting-state connectivity does not so far provide an accurate biomarker for identifying patients at the individual level.

Frontiers in psychiatry 14 1168100-1168100 2023年4月17日 査読有りPurpose: There is a lack of evidence regarding answers for clinical questions about treating insomnia disorder. This study aimed to answer the following clinical questions: 1) how to use each hypnotic and non-pharmacological treatment differently depending on clinical situations and 2) how to reduce or stop benzodiazepine hypnotics using alternative pharmacological and non-pharmacological treatments. Methods: Experts were asked to evaluate treatment choices based on 10 clinical questions about insomnia disorder using a nine-point Likert scale (1=“disagree” to 9=“agree”). The responses of 196 experts were collected, and the answers were categorized into first-, second-, and third-line recommendations. Results: The primary pharmacological treatment, lemborexant (7.3±2.0), was categorized as a first-line recommendation for sleep initiation insomnia, and lemborexant (7.3±1.8) and suvorexant (6.8±1.8) were categorized as the first-line recommendations for sleep maintenance insomnia. Regarding non-pharmacological treatments for primary treatment, sleep hygiene education was categorized as the first-line recommendation for both sleep initiation (8.4±1.1) and maintenance insomnia (8.1±1.5), while multicomponent cognitive behavioral therapy for insomnia was categorized as the second-line treatment for both sleep initiation (5.6±2.3) and maintenance insomnia (5.7±2.4). When reducing or discontinuing benzodiazepine hypnotics by switching to other medications, lemborexant (7.5±1.8) and suvorexant (6.9±1.9) were categorized as first-line recommendations. Conclusion: Expert consensus indicates that orexin receptor antagonists and sleep hygiene education are recommended as first-line treatments in most clinical situations to treat insomnia disorder.

Neuropsychology 37(3) 315-329 2023年3月OBJECTIVE: A major limitation of current suicide research is the lack of power to identify robust correlates of suicidal thoughts or behavior. Variation in suicide risk assessment instruments used across cohorts may represent a limitation to pooling data in international consortia. METHOD: Here, we examine this issue through two approaches: (a) an extensive literature search on the reliability and concurrent validity of the most commonly used instruments and (b) by pooling data (N ∼ 6,000 participants) from cohorts from the Enhancing NeuroImaging Genetics Through Meta-Analysis (ENIGMA) Major Depressive Disorder and ENIGMA-Suicidal Thoughts and Behaviour working groups, to assess the concurrent validity of instruments currently used for assessing suicidal thoughts or behavior. RESULTS: We observed moderate-to-high correlations between measures, consistent with the wide range (κ range: 0.15-0.97; r range: 0.21-0.94) reported in the literature. Two common multi-item instruments, the Columbia Suicide Severity Rating Scale and the Beck Scale for Suicidal Ideation were highly correlated with each other (r = 0.83). Sensitivity analyses identified sources of heterogeneity such as the time frame of the instrument and whether it relies on self-report or a clinical interview. Finally, construct-specific analyses suggest that suicide ideation items from common psychiatric questionnaires are most concordant with the suicide ideation construct of multi-item instruments. CONCLUSIONS: Our findings suggest that multi-item instruments provide valuable information on different aspects of suicidal thoughts or behavior but share a modest core factor with single suicidal ideation items. Retrospective, multisite collaborations including distinct instruments should be feasible provided they harmonize across instruments or focus on specific constructs of suicidality.

Behavioural and cognitive psychotherapy 51(3) 1-6 2023年2月3日BACKGROUND: Guided parent-delivered cognitive behavioural therapy (GPD-CBT) is an effective low-intensity treatment for childhood anxiety disorder in Western countries and can increase access to evidence-based psychological therapies. AIM: This study aimed to examine its feasibility in a Japanese sample. METHOD: Twelve children with anxiety disorders and their parents participated in the study, and ten children and parents completed the program. Participants were assessed at pre-, post- and one-month follow-up using a diagnostic interview for anxiety disorders, self- and parent-report measures for anxiety, depression, parental behaviour, and parental anxiety. RESULTS: Four children (40% of completers) were free from their primary diagnoses immediately following the brief treatment, and seven children (70%) at the one-month follow-up. Changes in disorder severity, child and parent reported anxiety symptoms, and child reported depression symptoms were consistent with those found in Western trials of GPD-CBT and of Japanese trials of more intensive CBT for child anxiety disorders that involves both the child and the parent. Moderate increases were also found in child reported parental autonomy behaviours; however, there were only small changes in parent self-reported anxiety. CONCLUSION: These results support the potential of GPD-CBT to increase access to evidence-based treatments for anxiety disorders in Japanese children.

Frontiers in psychiatry 14 1233564-1233564 2023年INTRODUCTION: Previous neuroimaging studies in social anxiety disorders (SAD) have reported potential neural predictors of cognitive behavioral therapy (CBT)-related brain changes. However, several meta-analyses have demonstrated that cognitive therapy (CT) was superior to traditional exposure-based CBT for SAD. OBJECTIVE: To explore resting-state functional connectivity (rsFC) to evaluate the response to individual CT for SAD patients. METHODS: Twenty SAD patients who attended 16-week individual CT were scanned pre- and post-therapy along with twenty healthy controls (HCs). The severity of social anxiety was assessed with the Liebowitz Social Anxiety Scale (LSAS). Multi-voxel pattern analysis (MVPA) was performed on the pre-CT data to extract regions associated with a change in LSAS (∆LSAS). Group comparisons of the seed-based rsFC analysis were performed between the HCs and pre-CT patients and between the pre-and post-CT patients. RESULTS: MVPA-based regression analysis revealed that rsFC between the left thalamus and the frontal pole/inferior frontal gyrus was significantly correlated with ∆LSAS (adjusted R2 = 0.65; p = 0.00002). Compared with HCs, the pre-CT patients had higher rsFCs between the thalamus and temporal pole and between the thalamus and superior/middle temporal gyrus/planum temporale (p < 0.05). The rsFC between the thalamus and the frontal pole decreased post-CT (p < 0.05). CONCLUSION: SAD patients had significant rsFC between the thalamus and temporal pole, superior/middle temporal gyrus, and planum temporale, which may be indicators of extreme anxiety in social situations. In addition, rsFC between the thalamus and the frontal pole may be a neuromarker for the effectiveness of individual CT.

BMC Psychiatry 22(1) 2022年12月Abstract Background Due to the coronavirus disease 2019 (COVID-19) pandemic, people have undermined their mental health. It has been reported that post-COVID conditions at a certain rate. However, information on the mental health of people with post-COVID conditions is limited. Thus, this study investigated the relationship between post-COVID conditions and mental health. Methods Design of the present study was an International and collaborative cross-sectional study in Japan and Sweden from March 18 to June 15, 2021. The analyzed data included 763 adults who participated in online surveys in Japan and Sweden and submitted complete data. In addition to demographic data including terms related to COVID-19, psychiatric symptoms such as depression, anxiety, and post-traumatic stress were measured by using the fear of COVID-19 scale (FCV-19S), Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 item (GAD-7), and Impact of Event Scale-Revised (IES-R). Results Of the 135 COVID-19 survivors among the 763 total participants, 37.0% (n = 50/135) had COVID-19-related sequelae. First, the results of the Bonferroni-corrected Mann Whitney U test showed that the group infected SARS-CoV-2 with post-COVID conditions scored significantly higher than those without one and the non-infected group on all clinical symptom scales (P ≤ .05). Next, there was a significant difference that incidence rates of clinical-significant psychiatric symptoms among each group from the results of the Chi-squared test (P ≤ .001). Finally, the results of the multivariate logistic model revealed that the risk of having more severe clinical symptoms were 2.44–3.48 times higher among participants with post-COVID conditions. Conclusion The results showed that approximately half had some physical symptoms after COVID-19 and that post-COVID conditions may lead to the onset of mental disorders. Trial registration The ethics committee of Chiba University approved this cross-sectional study (approval number: 4129). However, as no medical intervention was conducted, a clinical trial registration was not necessary.

BMC psychiatry 22(1) 658-658 2022年10月25日BACKGROUND: Although several school-based cognitive behavioural intervention programmes have been developed in Japan to prevent and improve children's anxiety disorders, the substantial time required for their completion remains a problem. METHODS: A brief version of the cognitive behavioural programme called 'Journey of the Brave', developed for Japanese children was conducted among 90 children aged 10‒11 years using 20-min short classroom activities, and its effectiveness was examined. The children were divided into two groups: the intervention (n = 31) and control groups (n = 59). The control group did not attend any programme sessions and followed regular school curriculum. We conducted 14 weekly programme sessions and assessed children at pre-intervention, post-intervention, and 2-month follow-up (6 months after the beginning). The primary and secondary outcome measures were the Spence Children's Anxiety Scale (SCAS) to assess children's anxiety symptoms and the Strengths and Difficulties Questionnaire (SDQ) to measure behaviour problems, respectively. RESULTS: A statistically significant reduction in the SCAS score in the intervention group was found at 2-month follow-up compared with the control group. A significant reduction was also observed in the SDQ score. CONCLUSIONS: Our findings suggested that the 'Journey of the Brave' programme, which requires only 5 h of short classroom activities, demonstrates promising results compared with previous programmes. A larger randomised control trial would be desirable. TRIAL REGISTRATION: UMIN, UMIN000009021, Registered 10 March 2012.

JMIR Pediatrics and Parenting 5(4) e35466-e35466 2022年10月5日Background Parents of adolescents with internet addiction are confronted with their children’s internet problems on a daily basis. Parents may notice that adolescents with addiction may also have emotional and behavioral problems, including impulsivity and violence. Parenting styles have been found to be related to internet addiction. Objective The purpose of this study is to investigate parents’ perspectives on their parenting style, relationship with their child, and the degree of internet addiction and emotional and behavioral problems of their child. Methods A web survey was conducted with 600 parents of children between the ages of 12 and 17 years, from October 14 to 18, 2021, across Japan. Respondents were recruited by an internet research company and were asked to complete an anonymous online questionnaire. The survey was divided into two groups: 300 parents who answered “yes” to the question “Do you think your child is dependent on the internet?” and 300 parents who answered “no” to that question. Questionnaires were collected until each group had 300 participants. The questionnaire included (1) the Parent-Child Internet Addiction Test (PCIAT), (2) the daily time spent using the internet, (3) the Strengths and Difficulties Questionnaire (SDQ), (4) the Parenting Style and Dimensions Questionnaire (PSDQ), and (5) the Relationship Questionnaire (RQ) measuring self-report attachment style prototypes. Results Mean scores of the PCIAT and the daily time spent using the internet for the groupwith probable internet addiction were significantly higher than those of the group without probable internet addiction (50%; P<.001). The total difficulties score from the SDQ for the group with probable internet addiction (mean 10.87, SD 5.9) was significantly higher than that for the group without probable internet addiction (mean 8.23, SD 5.64; P<.001). The mean score for authoritarian parenting from the PSDQ for the group with probable internet addiction (mean 2.1, SD 0.58) was significantly higher than that for the group without probable internet addiction (mean 2.1, SD 0.58; P<.001). Regarding the RQ, there were no significant differences between the two groups. Conclusions Our findings suggest that parents who think their child is addicted to the internet may recognize emotional and behavioral problems of the child and have an authoritarian parenting style.

2022年9月29日<p>Purpose: To examine the reliability and validity of the Camouflaging Autistic Traits Questionnaire–Japanese version (CAT-Q-J). Methods: Self-report questionnaires were administered to 204 adults with and 410 adults without autism. Test–retest reliability was confirmed via another survey administered after two weeks.Results: The overall CAT-Q-J showed good reliability, correlating approximately with other scales, supporting its convergent validity. However, a few subscales had insufficient reliability and validity. Exploratory factor analyses showed three factors similar to the original in non-autistic sample (plus a factor comprising reversed items). For the autistic sample, three factors partially differed from the original. Conclusion: Despite acceptable consistency, reliability, and validity at an overall level, the CAT-Q-J should be used with caution.</p>

Journal of Rehabilitation Medicine jrm00336-jrm00336 2022年9月29日Objective: To examine whether alternating training with both the non-paretic and paretic sides (alternating bilateral training), expecting trial-to-trial inter-limb transfer of training effects from the nonparetic to the paretic side, improves upper-limb motor performance in post-stroke patients, compared with unilateral training involving only the paretic side.Design: An assessor-blinded pilot randomized controlled trial.Subjects: Twenty-four right-handed post-stroke patients with hemiparesis.Methods: Participants were randomly allocated to either an alternating bilateral training group or a unilateral training group (n = 12/group). Participants underwent dexterity training of the paretic arm using the Nine-Hole Peg Test, completing 10 trials/day for 7 consecutive days. The alternating bilateral training group additionally performed alternating trials with the non-paretic limb. Performance change, assessed 1 day and 1 week after the 7-day training period, was compared between groups.Results: Although the improvement was comparable in both groups at both post-training time-points, a sub-analysis in which those with left hemiparesis and those with right hemiparesis were analysed separately revealed potential benefits of the alternating bilateral training, specifically for those with left hemiparesis.Conclusion: Alternating bilateral training may augment training effects and improve upper-limb motor function in patients with left hemiparesis.
