The study tools used in this research was Ryff’s Psychological Well-being Scale (RPWS). A pretest was administered to both the experimental and control groups. Then, the positive psychology intervention was administered to the experimental group, and the control group did not receive any intervention. At the end of the training, the post-test was taken for both groups. The results of the Multivariate Analysis of Variance (MANOVA) indicate that positive psychology significantly increased psychological well-being among the experimental group compared to the control group. The results also showed a significant difference between the mean scores of RPWS of psychological well-being in the experimental and the control group in the post-test (P<0.001). The positive psychology intervention method had a significant effect on autonomy, environmental mastery, personal growth, positive relation with others, purpose in life, and self-acceptance (P<0.001). The interventional method of positive psychology can increase the psychological well-being of adolescents.
