The present study aimed to evaluate the feasibility of moral neuroscience training based on Dweck's growth mindset on the social skills of adolescents externalizing behavioral problems. The research method was quasi-experimental with a pre-test-post-test design, a control group, and a one-month follow-up stage. The statistical population included all male high school students in Urmia in the academic year 2023-2024. After selecting an available school and completing the youth self-report scale (YSR) and the moral growth mindset scale (MGM), 30 students classified with the symptoms of externalizing behavioral problems and fixed moral mindset were randomly assigned to two groups of 15 subjects. For 12 sessions of 90 minutes, the experimental group underwent moral neuroscience package training based on Dweck's growth mindset approach. Social Skills Rating Scale (Gresham & Elliott, 1990) was used to collect data. Data analysis was done using the statistical variance analysis method with repeated measures. The results showed that moral neuroscience training based on Dweck's growth mindset in the post-test and follow-up stages significantly affected the experimental group's self-control, empathy, and cooperation (p<0.05). However, no significant difference was observed in the component of assertion between the two groups (p>0.05). Based on the findings, the moral neuroscience training package based on Dweck's growth mindset can effectively improve the social skills of adolescent students with externalized behavioral problems.
