A randomized controlled pilot study evaluating Worry Less, Live More: The Mindful Way Through Anxiety Workbook

Effective interventions for generalized anxiety exist, but barriers to treatment prevent their broad dissemination. Commercially available self-help materials may help bridge this gap, but few have been empirically evaluated. This study compared self-reported change in generalized anxiety symptomology and associated problems between community members with excessive worry who were randomly assigned to receive the Worry Less, Live More: The Mindful Way through Anxiety Workbook (n = 35) and those in a delayed condition (n = 29). Participants in the workbook condition reported significantly greater reductions between baseline and 11-week follow-up in self-reported worry (η² =.15), general anxiety/tension (η² =.13), and anxiety (η² =.24) than those in the delayed condition, although no statistically significant differences across condition on changes in depression, functional impairment or acceptance were detected. This pilot study provides support for continued research examining the efficacy of acceptance-based behavioral therapy delivered in a self-help format.
