Purpose: The purpose of the present study was to determine the effectiveness of life skills training on coping strategies and psychological capital of adolescents. Methodology: The research design was quasi-experimental with pretest-posttest design with the control group. The statistical population of this study consisted of all female high school students in the 4th District of Tehran in the academic year of 1396-97. According to Cohen's table, the sample size was 30 people. The initial random sampling method was used, but the participants in the control and experimental groups were randomly assigned and 15 individuals in the experimental group and 15 in the control group were replaced. The measuring tools included Lazarus's Coping Strategies Scale (1985) and Lutz's Psychological Capital Scale (2007), which subjects completed before and after the life skills training program. Analysis of variance (ANOVA) was performed using Spss21 software at a significant level of 0.05. Findings: The results showed that life skills training (14.3%) played a role in explaining the problem-focused coping strategy, but it was not effective in the emotion-focused coping strategy (P = 0.824). Life was 19.7% in explaining self-efficacy, 23.2% in explaining hope, and 17.1% in explaining the resilience of the experimental group. But the experiment group was not optimistic (P = 0.904). Conclusion: Based on the findings, it can be concluded that life skills training has been effective in coping strategies and psychological capital of adolescents.
