Official title
A Randomized Controlled Trial (RCT) Comparing Acceptance and Commitment Therapy (ACT) and Cognitive Behavioral Therapy (CBT) Self-help Books for Depression
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to compare the efficacy of acceptance and commitment therapy (ACT) and cognitive behavioral therapy (CBT) for depression in a bibliotherapy format and assess hypothesized mechanisms of change in depression symptomatology, quality of life, and functioning. This study will test the following hypotheses: 1. CBT and ACT will both result in decreased depression, distress, and self-stigma associated with depression. Life satisfaction and values progress will increase in both conditions. 2. CBT will result in greater use of reappraisal than ACT. 3. ACT will results in greater use of defusion and decreased psychological inflexibility than CBT. 4. Changes in experiential avoidance and defusion will predict changes in depression in the ACT condition. 5. Changes in reappraisal will predict changes in depression in the CBT condition. 6. Participants who are given their choice of treatment will show better adherence and satisfaction in the intervention.
