Acceptance and Commitment Therapy on Psychological Flexibility, Values, and Well-Being: A Single-Case Experimental Study

The goal of this clinical trial is to evaluate the effects of a brief Acceptance and Commitment Therapy (ACT)-based group intervention on psychological flexibility, values-based functioning, and psychological well-being in university students aged 18 to 28 years presenting elevated levels of emotional distress and psychological risk indicators. The main questions it aims to answer are: Does a brief ACT-based intervention reduce experiential avoidance and cognitive fusion in university students? Does the intervention improve present-moment awareness, values-based functioning, life satisfaction, and psychological flourishing? Participants will: Complete repeated self-report assessments across 13 measurement points distributed throughout baseline, intervention, and follow-up phases. Participate in five weekly ACT-based group intervention sessions delivered by trained clinical psychologists. Engage in experiential ACT exercises focused on acceptance, mindfulness, cognitive defusion, values clarification, and committed action. Complete between-session activities and behavioral practices related to the ACT processes addressed during the intervention. Participate in follow-up assessments to evaluate maintenance of treatment effects over time.
