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

26. maj 2026 opdateret af: Universidad del Valle, Colombia

Acceptance and Commitment Therapy on Psychological Flexibility, Values, and Well-Being

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.

Detaljeret beskrivelse

University students frequently experience elevated levels of emotional distress, including symptoms of anxiety, depression, stress, worry, and psychological maladjustment. Brief interventions based on Acceptance and Commitment Therapy (ACT) have shown promising results in reducing experiential avoidance and cognitive fusion while promoting psychological flexibility and well-being.

The present study evaluates the effects of a brief ACT-based intervention protocol delivered in a group format using a Single-Case Experimental Design (SCED) with repeated measurements across baseline, intervention, and follow-up phases. The intervention focuses on core ACT processes, including acceptance, cognitive defusion, present-moment awareness, values clarification, and committed action.

Participants completed repeated assessments of psychological flexibility processes and well-being indicators across thirteen measurement points distributed throughout the study phases. The investigators hypothesize that the ACT-based intervention will produce reductions in experiential avoidance and cognitive fusion, together with improvements in present-moment awareness, values-based functioning, life satisfaction, and flourishing.
