ABSTRACT
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 â =â 6.52, P â =â .003), PDAS ( F â =â 5.68, P â =â .01), European quality of life 5-dimensions 5-level ( F â =â 3.82, P â =â .03), and BDI ( F â =â 4.61, P â =â .01) exhibited significant changes ( P â <â .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 â >â .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.

BACKGROUND: Cognitive behavioral therapy is known to improve the management of chronic pain. However, the components of this therapy are still being investigated and debated. OBJECTIVE: This study aimed to examine the effectiveness of an integrated cognitive behavioral therapy program with new components (attention-shift, memory work, video feedback, and image training) delivered via videoconferencing. METHODS: This study was unblinded and participants were recruited and assessed face-to-face in the outpatient department. We conducted a randomized controlled trial for chronic pain to compare 16 weekly videoconference-based cognitive behavioral therapy (vCBT) sessions provided by a therapist with treatment as usual (TAU). Thirty patients (age range, 22-75 years) with chronic pain were randomly assigned to either vCBT (n=15) or TAU (n=15). Patients were evaluated at week 1 (baseline), week 8 (midintervention), and week 16 (postintervention). The primary outcome was the change in pain intensity, which was recorded using the numerical rating scale at 16 weeks from the baseline. Secondary outcomes were pain severity and pain interference, which were assessed using the Brief Pain Inventory. Additionally, we evaluated disability, pain catastrophizing cognition, depression, anxiety, quality of life, and cost utility. RESULTS: In the eligibility assessment, 30 patients were eventually randomized and enrolled; finally, 15 patients in the vCBT and 14 patients in the TAU group were analyzed. Although no significant difference was found between the 2 groups in terms of changes in pain intensity by the numerical rating scale scores at week 16 from baseline (P=.36), there was a significant improvement in the comprehensive evaluation of pain by total score of Brief Pain Inventory (-1.43, 95% CI -2.49 to -0.37, df=24; P=.01). Further, significant improvement was seen in pain interference by using the Brief Pain Inventory (-9.42, 95% CI -14.47 to -4.36, df=25; P=.001) and in disability by using the Pain Disability Assessment Scale (-1.95, 95% CI -3.33 to -0.56, df=24; P=.008) compared with TAU. As for the Medical Economic Evaluation, the incremental cost-effectiveness ratio for 1 year was estimated at 2.9 million yen (about US $25,000) per quality-adjusted life year gained. CONCLUSIONS: The findings of our study suggest that integrated cognitive behavioral therapy delivered by videoconferencing in regular medical care may reduce pain interference but not pain intensity. Further, this treatment method may be cost-effective, although this needs to be further verified using a larger sample size.

BACKGROUND: We aimed to examine the feasibility of our newly-developed, integrated, and high-intensity individual cognitive behavioral therapy (CBT) protocol for treatment-resistant chronic pain. METHODS: We conducted an open-labeled prospective single-arm trial for patients aged 18 years and above, suffering from chronic pain, and diagnosed with somatic symptom disorder with predominant pain. We provided 16 weekly sessions of CBT, each lasting for 50 minutes, which included 4 new strategies: attention shift, memory work, mental practice, and video feedback. For comparison, the study had a pre-test post-test design. The primary outcome was the change from baseline (week 1) to 16, as indicated by the Numerical Rating Scale and Pain Catastrophizing Scale. In addition, we evaluated depression, anxiety, disability, and quality of life as secondary outcomes. RESULTS: Sixteen patients with chronic pain underwent our CBT program. Though there was no reduction in pain intensity, catastrophic cognition showed statistically significant improvement with a large effect size. Depression, anxiety, and disability demonstrated statistically significant improvements, with small to moderate effect sizes. No adverse events were reported. CONCLUSION: Our newly integrated CBT program for chronic pain may improve catastrophic cognition, depression, anxiety, and disability. Large-scale randomized controlled studies are necessary to investigate the program's effectiveness in the future.

BACKGROUND: Mental imagery has a more powerful impact on our emotions than thinking in words about the same material. Treating intrusive images with imagery rescripting (IR) has been reported for various disorders, including post-traumatic stress disorder, social anxiety disorder, and bipolar disorder. There has been less research about IR as a major depressive disorder (MDD). AIMS: We examined whether IR without focusing on early traumatic memories is effective in MDD. METHODS: We enrolled 19 participants with MDD, who received 15 weekly sessions of full CBT, including two sessions for IR of intrusive images and, separately, for memory rescripting. Before and after the IR intervention, participants were asked to rate the intrusive images they experienced against, an intrusion index that included difficulty (interference with daily life), uncontrollability, distress caused by the negative image, and vividness. We recorded the contents of each participant's negative and positive imagery to classify these. RESULTS: The intrusion index scores decreased after the IR sessions. Negative images experienced by the participants while in a depressive mood were categorized into three different types: blame, social exclusion, and loneliness. The rescripted positive images were categorized into good relations and worthy self (competent self). CONCLUSIONS: These results suggest that IR of intrusive images without focusing on early traumatic memories may usefully be incorporated into routine CBT sessions for MDD.
