The present research aimed to investigate the effectiveness of short-term and long-term life skills training in decreasing the aggression among the adolescents. The sample comprised 400 male and female students studying in the high schools of Karaj, who responded to two questionnaires of Life Skills and Aggression Questionnaire and based on their mean score were randomly assigned to the experimental and control groups (100 male and 100 female). Subsequent to ten life skills training sessions for the experimental group, both groups were reassessed by both of the questionnaires. Covariance analysis indicated that increase of life skills decreased the level of aggression among the individuals. In order to test out the stability of the training effects, two 30-individual groups with low and high scores were selected and were tested in terms of the research variables. Results demonstrated that in the first six month, the mean of groups decreased. However, this was desirable according to the psychological statistics. It's worth mentioning that, the weak group demonstrated a greater decrease. Furthermore, in the second six month, the weak group attended five training sessions which increased their level of life skills and decreased the level of aggression to a more considerable level as compared to the strong group which resulted in lower mean by the end of the training. It can be concluded that the repetition of the training with time interval increases the level of awareness and mastery of life skills and we can evidence higher decrease of aggression and more stability of the results

The present study aimed to examine the effectiveness of life skills training on internalized shame and perceived stress among university students. This research was conducted using a quasi-experimental design with a pretest–posttest control group and a two-month follow-up. The study population consisted of students at the Islamic Azad University, Shiraz Branch, in 2024, from whom 72 participants were selected through convenience sampling and randomly assigned to experimental and control groups (36 in each group). The research instruments included the Internalized Shame Scale (Cook) and the Perceived Stress Scale (Cohen). The experimental group received life skills training based on Kleinke’s protocol in 10 weekly sessions of 45 minutes, while the control group received no intervention. Data were analyzed using repeated measures analysis of variance. The results indicated that life skills training led to a significant reduction in internalized shame and perceived stress in the experimental group compared to the control group (p < 0.05), and these effects were maintained at follow-up. The findings suggest that life skills training is an effective educational and preventive intervention for improving mental health indicators among university students and can be incorporated into student mental health promotion programs.
