A Web-Based Program Reduces Depressive Symptoms

Researchers from the University of Twente in The Netherlands compared the effectiveness of a guided web-based intervention for depression, based on Acceptance and Commitment Therapy (ACT), with an active control condition (expressive writing) and a waiting-list control condition,

Adults with depressive symptoms from the general population were randomized to the three conditions: ACT (n = 82), expressive writing (n = 67) or waiting-list control (n = 87). The main outcome assessed was reduction in depressive symptoms, as measured by the Center for Epidemiological Studies Depression Scale.

The investigators found significant reductions in depressive symptoms following the ACT intervention, as compared with the control group (Cohen's d = 0.56) and the expressive writing intervention (d = 0.36). The effect sizes were sustained at 6-month and 12-month follow-up.

The researchers conclude that Acceptance and Commitment Therapy, delivered as a web-based public mental health intervention for adults with depressive symptoms, can be effective.
