The Effectiveness of Strengths-Based Treatments for Impulsivity and Self-control in Adolescents with Binge-Eating Disorders

Abstract

Background: There are various educational programs based on theoretical frameworks for binge-eating disorders. However, there is no evidence for Strengths-Based approach targeting low inhibitory control and impulsivity of the patients. Objectives: This experimental study explored the effect of a Strengths-Based clinical teaching course on impulsivity and self-control of adolescents with binge-eating disorder. Materials & Methods: The study was a quasi-experimental design with pre-test and posttest evaluations on adolescents with binge-eating disorders in clinical psychology in Kermanshah. A total of 26 adolescents with binge-eating disorders were randomly assigned to the experimental (n=13) and control (n=13) groups. Then, they were asked to fill out a questionnaire about Barrat’s impulsivity scale and Tangney’s Self-Control Scale. The experimental group was taught methods and techniques of strengths-based strategies for eight 90-minute sessions followed by training sessions of strengths-based skills once a week for 2 months, whereas the control group received no psychological training during this time. After these sessions, both groups were given post-test evaluations. Data were compared using multivariate and univariate analysis of variance. Results: The age range of participants was 14-18 years. The mean post-test score showed that impulsivity was significantly decreased and self-control was significantly increased in the experimental group. The result of univariate analysis of variance indicate that the two groups differed significantly on impulsivity (F=15.91, P=0.001,ηp2=0.59) and self-control (F=17.25, P=0.001, ηp2=0.62). Conclusion: Using a strength approach offers effective self-control and impulsivity to adolescents with binge-eating disorders.
