This study evaluated two psychological interventions for adults with mild to moderate subthreshold anxious-depressive symptoms in primary care in Spain. Participants referred by general practitioners were randomly assigned to either (1) PADAP, a manualized transdiagnostic group program delivered in 10 weekly 90-minute sessions, or (2) a structured active single-session depathologizing intervention (SSDI), delivered individually in one 50-60-minute session.
The primary aim was to compare changes in depressive and anxiety symptoms from baseline to 12 months. Secondary aims included comparing primary care mental health-related consultations, psychotropic medication use, new contacts with mental health services, and perceived need for further mental health care during follow-up.
