Sudden gains in depression and anxiety during an online pain management programme for chronic pain.

BACKGROUND: Chronic pain is associated with depression and anxiety symptoms. Pain management programms, delivered face-to-face or via the internet, can effectively help adults manage the impacts of chronic pain. Sudden gains are defined as substantial, rapid, and lasting symptom reductions that occur between consecutive treatment sessions and have been associated with better treatment outcomes in non-pain samples. This study examined whether adults with chronic pain report sudden gains in depression or anxiety symptoms during an 8-week online pain management programme, and whether sudden gains were associated with better treatment outcomes for depression or anxiety. Dominant theories of sudden gains argue that therapists are required for sudden gains to be maintained and improve treatment outcomes. METHODS: Using data from a published randomized controlled trial (n = 338), sudden gains and treatment outcomes were compared across three levels of therapist guidance provided alongside the programme: weekly, optional, and self-guided. RESULTS: Similar rates of sudden gains were observed in depression (22%) and anxiety (24%) across the treatment period, and most sudden gains occurred between Weeks 1 and 2 of treatment. Therapist guidance was not associated with sudden gains; higher baseline symptom severity emerged as the only consistent predictor of sudden gain status. No significant differences in treatment outcomes for depression or anxiety symptoms between sudden gainers and non-gainers were observed across therapist guidance conditions. CONCLUSIONS: These results do not support an association between sudden gains in depression or anxiety symptoms and better post-treatment outcomes, at least for adults with chronic pain. SIGNIFICANCE STATEMENT: Sudden gains in depression and anxiety symptoms were not associated with improved treatment outcomes for adults with chronic pain who participated in an online pain management programme, regardless of the level of therapist guidance provided. These findings suggest possible differences in symptom change in chronic pain samples compared to general population samples.

Cognitive behavioral therapies for depression and anxiety in people with chronic disease: A systematic review and meta-analysis.

OBJECTIVE: Anxiety and depression in chronic disease are common and burdensome co-morbidities. There has been growing interest in cognitive and behavioral therapies (CBTs) for anxiety and depression in chronic disease, however their efficacy has not been well-established. This study examined the efficacy of CBTs for depression and/or anxiety symptoms within chronic disease and explored the moderating role of clinical and methodological characteristics. METHODS: Following prospective registration, electronic databases were searched up to 2023 for randomized controlled trials (RCTs) examining CBTs for depression and/or anxiety in any adult chronic disease population. RESULTS: We included 56 RCTs. The overall effect of CBTs was g = 0.61 (95% CI, 0.49, 0.72) for depression and g = 0.56 (95% CI, 0.42, 0.70) for anxiety. A range of methodological features significantly moderated the effect sizes obtained, including type of control group and the outcome measure used. Risk of Bias ratings indicated some concerns regarding RCT conduct and reporting. CONCLUSIONS: CBTs lead to moderate improvements in both depression and anxiety symptoms among people with chronic disease. However, the efficacy of CBT should be interpreted considering certain study and sample characteristics. It is recommended that future studies make improvements to study methodology and reporting.

Depression and Anxiety Trajectories in Chronic Disease: A Systematic Review and Meta-Analysis.

INTRODUCTION: People living with chronic diseases are at an increased risk of anxiety and depression, which are associated with poorer medical and psychosocial outcomes. Many studies have examined the trajectories of depression and anxiety in people with specific diseases, including the predictors of these trajectories. This is valuable for understanding the process of adjustment to diseases and informing treatment planning. However, no review has yet synthesised this information across chronic diseases. METHODS: Electronic databases were searched for studies reporting trajectories of depression or anxiety in chronic disease samples. Data extracted included sample characteristics, results from trajectory analyses, and predictors of trajectories. Meta-analysis of the overall pooled prevalence of depression and anxiety trajectories was conducted, and qualitative synthesis of disease severity predictors was undertaken. RESULTS: Following search and screening, 67 studies were included (N = 61,201 participants). Most participants followed a stable nonclinical trajectory for depression (69.0% [95% CI: 65.6, 72.2]) and anxiety (73.4% [95% CI: 66.3, 79.5]). Smaller but meaningful subsamples followed a trajectory of depression and anxiety symptoms consistently in the clinical range (11.8% [95% CI: 9.2, 14.8] and 13.7% [95% CI: 9.3, 19.7], respectively). Several clinical and methodological moderators emerged, and qualitative synthesis suggested that few aspects of disease severity were associated with participants' trajectories. CONCLUSION: Most people with chronic disease follow a trajectory of distress that is low and stable, suggesting that most people psychologically adjust to living with chronic disease. Evidence also suggests that the nature and severity of the disease are not meaningful predictors of psychological distress.
