Abstract
Background: The undesirable conditions resulting from addiction can be mitigated with timely diagnosis and effective interventions. Distress tolerance can be promoted in adolescents with a drug-dependent parent. Objectives: The present study aimed to investigate the effectiveness of mindfulness-based stress reduction (MBSR) therapy and emotion regulation training (ERT) on the distress tolerance of adolescent girls with a drug-dependent parent in Ahvaz, Iran. Methods: This clinical trial was performed on the experimental and control groups as the pretest-posttest design with follow-up. The statistical population included all the adolescent girl students with a drug-dependent parent in Ahvaz. The sample consisted of 45 adolescents with a drug-dependent parent selected by cluster sampling. The participants were randomly divided into two experimental groups of MBSR (eight 60-min sessions) and ERT (eight 45-min sessions) and a control group (n = 15 per group). All three groups were followed up after 45 days. The research instrument was the Distress Tolerance Scale (DTS), and data were analyzed using the analysis of covariance. Results: MBSR and ERT enhanced distress tolerance in adolescent girls with a drug-dependent parent (P < 0.001). The effects of the two interventions were not significantly different, and this result persisted in the follow-up stage. Conclusions: MBSR and ERT increased distress tolerance in adolescent girls with a drug-dependent parent. Therefore, these two interventions can be administered to enhance the mental health of adolescents.
