The present study aimed to analyze and compare the psychological profiles of two groups of traditional and industrial drug users, examining the differences in brain-behavioral systems, personality dimensions, and prosocial behavior tendencies. This causal-comparative study was conducted on 200 drug-dependent men (100 traditional drug users and 100 industrial drug users) who had referred to rehabilitation centers in Qom in 1404. The measurement tools included the Gray-Wilson Brain-Behavioral Systems Questionnaire, Cloninger Personality and Character Test, and the Revised Prosocial Behavior Scale. The findings from multivariate analysis of variance showed that industrial drug users scored significantly higher in the behavioral activation system and the approach and active avoidance subscales, while no significant differences were observed in the behavioral inhibition and conflict-avoidance systems. In terms of personality dimensions, the industrial group had higher scores in novelty seeking, harm avoidance, perseverance, self-direction, and self-transcendence, but traditional users showed superiority in the reward dependence dimension and indicators of social behavior (altruism and compliance). The results indicate that the industrial substance use pattern is associated with a more impulsive personality profile and a deeper breakdown in social functioning, while traditional users maintained social bonds and responsiveness to environmental rewards. These findings emphasize the need to review treatment protocols and design differentiated interventions based on the type of substance used and the neuro-personality underpinnings in the field of addiction psychology.

The present study aimed to determine the effectiveness of Acceptance and Commitment Therapy (ACT) on the emotional schema of shame and emotional expressivity in adolescent boys with high social anxiety in District 13 of Tehran. This study employed a quasi-experimental design with a pretest–posttest and follow-up design with a control group. The statistical population consisted of all male students in the first and second levels of secondary school with high social anxiety in the 2025–2026 academic year. Using a multistage cluster sampling method, 30 students whose scores on the Social Anxiety Questionnaire were above the cutoff point were selected and randomly assigned to an experimental group (n = 15) and a control group (n = 15). The research instruments included the Leahy Emotional Schema Scale (2002), the Emotional Expressivity Scale (King & Emmons, 1990), and the Social Anxiety Questionnaire (Connor et al., 2000). The experimental group received Acceptance and Commitment Therapy in eight 120-minute sessions, whereas the control group received no intervention. Data were analyzed using repeated-measures analysis of variance in SPSS version 26. The results indicated that the effects of time, group, and the interaction between time and group on the dependent variables were statistically significant . Furthermore, Acceptance and Commitment Therapy led to a significant and sustained reduction in the emotional schema of shame and a significant increase in emotional expressivity in the experimental group compared with the control group at the posttest and follow-up stages. Based on the findings, Acceptance and Commitment Therapy can be considered an effective intervention for reducing the emotional schema of shame and improving emotional expressivity in adolescents with social anxiety.
