Group-Based Acceptance and Commitment Therapy Versus Active Control in University Students With Emotional Symptoms
Sponsor: Mónica Larrosa Signorelli
Summary
This study evaluates the efficacy of a group-based Acceptance and Commitment Therapy (ACT) protocol compared to a non-directive group therapy used as an active control condition in university students presenting moderate to moderate/high levels of emotional symptomatology. Emotional difficulties such as depressive and anxiety symptoms are highly prevalent among university students and may negatively affect academic performance, well-being, and long-term functioning. 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. Participants 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. Outcomes will include depressive and anxiety symptoms, psychological flexibility, repetitive negative thinking, and meaning in life. The study uses a multimethod assessment strategy combining traditional self-report questionnaires administered at baseline, post-intervention, and follow-up; Ecological Momentary Assessment (EMA) with daily and weekly measures during the intervention period; and qualitative interviews to explore participants' experiences.
