Psychological capital approaches and the mindfulness approach provide a practical and positive framework that helps to prevent and improve mental health. Objectives: The present study was conducted to compare the effectiveness of psychological capital and mindfulness training in improving the mental health of medical students at a military university in Tehran, Iran. Materials and Methods: The current experimental research was conducted based on a pretest-posttest design with a control group and follow-up in 2021. The research sample consisted of 75 medical faculty students who were randomly selected on the basis of their years of study and were then randomly divided into two experimental groups and one control group (n=25 each). Mental health questionnaire was used to collect data, and the variance method (with repeated measurements) was used for data analysis to test the hypotheses at a significance level of P≤0.05. Results: The means of mental health of experimental and control groups were not significantly different in the pre-test; however, under the influence of psychological capital and mindfulness training in the post-test and follow-up were significantly different between the two mentioned groups (F=52.132, Eta=0.592, P<0.001). These results showed the effectiveness of the mentioned methods to improve mental health. Conclusion: The findings of the present research indicated the effectiveness of group training in psychological capital and mindfulness on the improvement of mental health dimensions. Moreover, comparing the effectiveness of these two approaches on mental health dimensions showed the superiority of the mindfulness approach over psychological capital. Therefore, it is suggested that psychological capital and mindfulness group training programs be performed in educational centers, counseling and psychology centers, and medical and health centers to improve mental health.
