This pilot study investigates the effectiveness of Motivational Psychotherapy in reducing symptoms of depression and improving academic self-concept among adolescent girls in Iran. A total of 30 participants aged 13 to 17 were randomly assigned to an experimental group receiving Motivational Psychotherapy and a control group receiving no treatment. The intervention consisted of 8 weekly sessions based on the principles of motivational interviewing and was tailored to adolescent needs. Outcomes were measured using the Beck Depression Inventory-II (BDI-II) and the Academic Self-Concept Questionnaire (ASCQ). Results suggest the potential benefit of this culturally sensitive approach in non-Western adolescent populations.
This randomized controlled pilot trial evaluated the effectiveness of Motivational Psychotherapy in reducing depressive symptoms and improving academic self-concept among adolescent girls in Iran. A total of 30 participants aged 13-17 years were randomly assigned to either the Motivational Psychotherapy group or a no-intervention control group.
The intervention consisted of 8 weekly individual sessions (60 minutes each) based on a manualized Motivational Psychotherapy protocol, adapted for adolescents in a non-Western context. The sessions focused on resolving ambivalence, enhancing intrinsic motivation, and strengthening environmental support.
Outcome measures included the Beck Depression Inventory-II (BDI-II) for depressive symptoms and the Academic Self-Concept Questionnaire (ASCQ) for academic self-concept. Data were analyzed using ANCOVA to control for baseline differences between groups. The results showed significant improvement in depression scores and academic self-concept in the intervention group compared to the control group, supporting the feasibility and cultural relevance of Motivational Psychotherapy for adolescent mental health.
