With the significant increase in the computer and internet usage, the new concept of addiction to internet games is now considered as a new psychiatric disorder. The evidences have demonstrated that the internet gaming disorder is similar to drug addiction in terms of neurology, but just a few researches has been done in terms of brain functions. The aim of this project is to compare Inhibitory control and risky decision making among heroin and methamphetamine users, internet gaming disorders and normal people. To do so 180 men participants (45 persons in each group) were selected via simple nonrandom or convenience sampling. Subjects of the study were evaluated using go/no go and Balloon Risk Taking Task (BART) test. For analyzing the results multivariable analyze of variance was used. Results showed that inhibitory control in both substance abuse disorder and internet gaming disorder was significantly lower than normal group (P<0.001). Although internet gaming disorder group showed better performance in comparison with substance abuse disorder group. (P<0.001) Moreover, risky decision-making in internet gaming disorder group was similar to substance abuse disorder group and was significantly higher than normal group (P<0.001). Generally, there are relative similarity in impulsivity parameters particularly in risky decision-making and inhibitory control between internet gaming group and substance abuse group. This can lead to continue taking drugs or online gaming despite of their annoying consequences.

The present study aimed to compare the effectiveness of Schema Therapy and Transdiagnostic Treatment on cognitive emotion regulation among adolescent boys with Obsessive-Compulsive Disorder (OCD). This study employed a quasi-experimental design with a pretest–posttest, control group, and three-month follow-up. The statistical population consisted of 14- to 16-year-old adolescent boys diagnosed with OCD who were referred to psychological counseling centers and clinics (Rasta and Bavar) in Sari, Iran, during 2024–2025. From this population, 45 participants were selected using purposive sampling and were randomly assigned to three groups of 15 participants each. Data were collected using the Cognitive Emotion Regulation Questionnaire (CERQ) developed by Garnefski et al. (2006) and the Yale–Brown Obsessive-Compulsive Scale (Y-BOCS) developed by Goodman et al. (1989). The first experimental group received Young’s Schema Therapy protocol (2006), whereas the second experimental group underwent Barlow et al.’s Unified Transdiagnostic Treatment protocol (2011). Data were analyzed using repeated-measures analysis of variance (RM-ANOVA). The findings indicated a significant difference between the Schema Therapy and Transdiagnostic Treatment groups in cognitive emotion regulation scores (p < .05), with Schema Therapy producing greater improvements in cognitive emotion regulation. Furthermore, the absence of significant differences between the posttest and follow-up assessments demonstrated the stability and maintenance of the treatment effects over time. Overall, the findings suggest that although both therapeutic approaches are effective in improving the psychological functioning of adolescent boys with OCD, Schema Therapy yields substantially greater improvements in cognitive emotion regulation than Transdiagnostic Treatment.
