Purpose

The treatment of generalized anxiety disorder (GAD) in an accessible manner represents an unmet need for those with cardiovascular disease (CVD), given that patients with CVD experience numerous barriers for in-person treatment engagement. The research plan for the proposed pilot project will entail: (1) open study of the acceptability of the digital intervention (N=5), followed by (2) recruitment and randomization of 90 individuals with a history of acute CVD events and clinical levels of GAD symptoms to dCBT or a waitlist (Control) condition, using a 1.5:1 allocation (dCBT:Control).

Detailed Description

The treatment of generalized anxiety disorder (GAD) in an accessible manner represents an unmet need for those with cardiovascular disease (CVD), given that patients with CVD experience numerous barriers for in-person treatment engagement. A recent large-scale efficacy trial of digital cognitive behavior therapy (dCBT) for GAD demonstrated significant benefit relative to waitlist control with a large effect size. The research plan for the proposed pilot project will entail: (1) open study of the acceptability of the digital intervention, followed by (2) recruitment and randomization of 90 individuals with a history of acute CVD events and clinical levels of GAD symptoms to dCBT or a waitlist (Control) condition, using a 1.5:1 allocation (dCBT:Control). Assessments will occur at Week 0 (baseline), Week 3, Week 6, and Week 10 (post-treatment).
