Introduction Psychological tests are necessary to assess the mental state of individuals. Mental health is one of the important psychological indicators and is increasingly considered as having various aspects of well-being. The Mental Health Continuum-Short Form (MHC-SF) is a 14-item instrument that assesses mental health, focusing on emotional, psychological, and social well-being. The present study, the psychometric properties of the Persian version of the MHC-SF were examined in relation to its factor structure, internal consistency, construct validity, and gender measurement invariance among adolescents. Methods The population of this study was Iranian adolescents between 11-and 18-year-old who were enrolled in the seventh to twelfth grades. A convenience sample of 822 Adolescents from four large cities in the Iran (Tehran, Zanjan, Hamedan and Ghazvin) participated in the present study. Questionnaires were completed online. Statistical analyses to evaluate the factor structure, internal consistency, construct validity, gender and age factorial invariance were performed in SPSS and LISREL. Results According to the results of confirmatory factor analysis, the MHC-SF is composed of three factors: emotional, psychological, and social well-being. Reliability was confirmed by Cronbach’s alpha method and composite reliability (>0.7). Measurement invariance were confirmed among girls and boys. Convergent and divergent validity were also evaluated and confirmed by correlating the test score with similar and different tests. Conclusion This study confirmed the psychometric properties of MHC-SF in the Iranian adolescent community. This instrument can be used in psychological research and diagnostic evaluations.
