Clinical study results from a randomized controlled trial of cognitive behavioural guided self-help in patients with partially remitted depressive disorder.

Objectives Cognitive behavioural guided self-help has been shown to be effective in mild and moderate depressive disorder. It is not known, however, if it is effective in individuals with partially remitted depressive disorder, which is a serious clinical problem in up to 50-60% of treated patients. This study is the first one to examine the clinical benefit of this intervention in this patient population. Design For the purpose of this study, a single-blind, randomized controlled design was used. Method We randomized 90 individuals with partially remitted depressive disorder either to cognitive behavioural guided self-help plus psychopharmacotherapy ( n = 49) or psychopharmacotherapy alone ( n = 41). They were clinically assessed at regular intervals with ratings of depressive symptoms and stress-coping strategies over a 3-week run-in period and a 6-week treatment period. Results After 6 weeks, intention-to-treat analysis ( n = 90) showed that patients treated with cognitive behavioural guided self-help plus psychopharmacotherapy did not have significantly lower scores on the Hamilton Rating Scale of Depression (17-item version; HRSD-17) and on the Beck Depression Inventory ( BDI) compared to patients treated with psychopharmacotherapy alone. When negative stress-coping strategies were considered, there was a significant difference between the two groups at the end of treatment with respect to the BDI but not to the HRSD-17. Conclusions Guided self-help did not lead to a significant reduction in symptom severity in patients with partially remitted depressive disorder after a 6-week intervention. However, the intervention leads to a reduction of negative stress-coping strategies. Practitioner points Cognitive behavioural guided self-help did not significantly improve depressive symptoms measured with the Hamilton Rating Scale of Depression (17-item version; HRSD-17) in patients with partially remitted depressive disorder., Improvements were found in reducing negative stress-coping strategies for those allocated to the cognitive behavioural guided self-help, which significantly improved Beck Depression Inventory but not HRSD-17., These findings suggest that cognitive behavioural guided self-help may offer some assistance in managing negative stress-coping strategies.
