Doing What Matters in Times of Stress (DWM) is a transdiagnostic five-module guided self-help (GSH) intervention developed by the World Health Organization. %The original DWM included group guidance in-person. %It appeared efficacious in pilot trials and a cluster randomized-controlled trial. In a sample of individuals recruited from across the United States, we studied the feasibility and acceptability of an adaptation of DWM in which guidance was provided individually and remotely. We assessed internalizing symptoms, psychological well-being, work and social functioning, usability of the intervention, and emotion regulation over the course of six weeks. A total of 344 individuals started our baseline screening, and 215 completed it. Of those screened, 74% (n=159) qualified for the intervention. We reached most participants who qualified (67%, n=107) via phone to schedule a GSH session. Most of those scheduled attended a study session (84%, n=90), and most of those who attended a session completed more than half the treatment (83%, n = 75). Retention rates were comparable to meta-analytic estimates of dropout rates in GSH-CBT. Participants showed improvement on the K6, WHO5, WSAS, and ERQ subscales. Baseline acceptability on the SUS was high but did not improve over time. DWM is a freely available, seemingly efficacious transdiagnostic intervention for internalizing disorder symptoms.
