Group Therapy Based on ACT for Anxiety Management among University Students: Randomized Clinical Trial

Abstract

One in every five university students around the world is estimated to have some type of psychological disorder, considering anxiety disorders as the most prevalent. This study consists in a randomized clinical trial aimed to evaluate efficacy and effectiveness of a semi-structured group psychotherapy protocol based on the principles of Acceptance and Commitment Therapy (ACT) for the treatment of anxiety among university students. Participants were randomly allocated in the intervention and control groups. Pre- and post-intervention anxiety levels were measured using the General Anxiety Disorders-7 (GAD-7) questionnaire. The study sample was composed of 15 people, 10 of whom were allocated to the intervention group and 5 to the control group. Results were analyzed in two ways: 1) Per protocol analysis; and 2) Intention-to-treat analysis. This treatment reduced anxiety symptoms by 39.7% among patients who completed treatment (Per protocol, p=0.003) and by 30.8% among all those allocated to the intervention group (i.e., by Intention-to-treat, including dropouts, p=0.035), whereas controls showed no significant reduction in same period. Therefore, we recommend the use of this protocol within the university context as a viable alternative to individual counselling in situations of anxiety disorders. Future research with larger samples may contribute to consolidate this protocol.
