Registry record from ClinicalTrials.gov (NCT05540067). This is a study registration, not published results. Lead sponsor: Brown University. Recruitment status: ACTIVE_NOT_RECRUITING. Phase: PHASE2. Study type: INTERVENTIONAL. Enrollment: 240 participants (ESTIMATED). Conditions: Anxiety, Depression. Interventions: BEHAVIORAL: Acceptance-Based Behavior Therapy (ABBT); OTHER: Treatment-as-Usual (TAU). Primary outcome measures: Hamilton Anxiety Rating Scale (HAM-A) , 39 weeks; Quick Inventory of Depressive Symptomatology - Clinician Rating (QIDS-C) , 39 weeks. Brief summary: The overall aim of this program of research is to improve the mental health of people who identify as LGBTQ+ by increasing their social support through a brief intervention. The purpose of the proposed project is to establish the effectiveness of our empirically-supported, brief acceptance-based behavioral therapy (ABBT). To achieve the specific aims, the investigators will conduct a fully-powered, randomized clinical trial (n=240) with two treatment arms: treatment-as-usual (TAU) vs. ABBT.
