Comparing the Effectiveness of Parent-child Interaction Therapy, Cognitive-behavioural Therapy, and Their Combination in Adolescents With Problematic Sexual Behaviours

Objective: Sexual behaviour is one of the most important developmental experiences in adolescence and may lead to longterm consequences. This study aimed to compare the effectiveness of cognitive-behavioural therapy (CBT), parent-child interaction therapy (PCIT), and their combination on depression, family functioning, and parenting stress in adolescents with problematic sexual behaviours (PSBs). Methods: The sample consisted of ۳۵ female students (۱۰-۱۳ years old) with PSBs from schools in Guilan Province, Iran, during the ۲۰۲۳-۲۰۲۴ academic year. They were identified by purposive sampling and based on the Sexual Behaviour Checklist and a clinical interview and were randomly assigned (using a table of random numbers) to three experimental groups (two groups with ۱۲ participants and one group with ۱۱ participants). To measure the variables, Maria Kovacs children’s depression questionnaire, family functioning questionnaire, and parenting stress scale were used. after completing the questionnaires, the treatment sessions began. The pre-test, post-test design with three test groups was used, and data analysis was conducted using analysis of covariance (ANCOVA) with SPSS software, version ۲۷. Results: A statistically significant difference was observed among the experimental groups for depression (F=۴.۸۳, df=۲, P=۰.۰۱, observed power [OP]=۰.۷۸) and family functioning (F=۱۸.۱۴, df=۲, P=۰.۰۰۱, OP=۱.۰۰). However, no significant difference was observed among experimental groups for parenting stress (F=۲.۷۶, df=۲, P=۰.۰۸). Conclusion: According to the results, CBT-PCIT is more effective than CBT in reducing depression, and PCIT and CBT-PCIT are more effective than CBT for improving family functioning.
