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.

Cognitive-behavioral therapy (CBT) has been shown to have a small to medium effect on chronic pain, necessitating further research to identify which components of CBT work for which type of patient. Previously, we developed a high-intensity individual CBT protocol and conducted a single-arm, uncontrolled feasibility study for chronic pain. In the current study, we explored patients' experiences in CBT sessions, including tactile attention-shift training; memory work using the peak-end rule; mental practice of action using motor imagery rescripting; and video feedback, including mirror therapy. Fourteen patients with chronic pain completed 16 CBT sessions. The tactile attention-shift training was very helpful for two patients and somewhat helpful for five, memory work was helpful for nine, mental practice was very helpful for four and somewhat helpful for three, and visual feedback was very helpful for six patients. Effective methodologies for new chronic pain CBT components should be developed. [Journal of Psychosocial Nursing and Mental Health Services, 60(5), 45-54.].
