Acceptance and Commitment Therapy (ACT) is an evidence-based psychological intervention that aims to improve mental health by increasing psychological flexibility, the ability to act in accordance with personal values while remaining open to difficult internal experiences.\n\nParticipants will be randomly assigned to either (1) a structured ACT group intervention or (2) a non-directive supportive group intervention that controls for therapeutic attention and group support factors. The primary hypothesis is that participants receiving ACT will show greater reductions in emotional symptoms and greater improvements in psychological flexibility compared to the active control group.\n\nOutcomes will include depressive and anxiety symptoms, psychological flexibility, repetitive negative thinking, and meaning in life.
