Introduction: in recent years, physical attractiveness among male athletes received new standards and led to changes in attitudes related to muscle mass in them, which requires a comprehensive assessment. therefore, the aim of this study was to determine the psychometric properties of the drive for muscularity attitudes questionnaire among iranian athlete.   materials and methods: the present study was a correlational and validation study. the statistical population of this research included all in the team and individualized athletes in tehran, in 2016, that 300 athletes were selected through multistage cluster sampling, moreover, they responded to the research instrument including the drive for muscularity, drive for muscularity attitudes, exercise dependency (eds) and mindfulness inventory for sport (mis). data were analyzed using exploratory factor analysis, cronbach's alpha and pearson correlation by spss and lisrel software.results: exploratory factor analysis supports the original singlefactor pattern of the model that explains 32.27% of the variance. confirmatory factor analysis results also indicate the optimal fitness of the items. moreover, the model of criterion validity indicating a good correlation between dmaq with dmq, eds, mis and its subscales. furthermore, investigating the internal consistency through cronbach's alpha showed the satisfactory internal stability of the questionnaire. conclusion: based on the results of the study, the persian version of drive for muscularity attitudes questionnaire has appropriate reliability and validity in iranian athletes' population and it is an appropriate instrument for screening, and research opportunities in the field of sport psychology.

The statistical population of this research included all in the team and individualized athletes in Tehran, in 2016, that 300 athletes were selected through multistage cluster sampling, moreover, they responded to the research instrument including the drive for muscularity, drive for muscularity attitudes, exercise dependency (EDS) and mindfulness inventory for sport (MIS). Data were analyzed using exploratory factor analysis, Cronbach's alpha and Pearson correlation by SPSS and LISREL software.Results: Exploratory factor analysis supports the original singlefactor pattern of the model that explains 32.27% of the variance. Confirmatory factor analysis results also indicate the optimal fitness of the items. Moreover, the model of criterion validity indicating a good correlation between DMAQ with DMQ, EDS, MIS and its subscales. Furthermore, investigating the internal consistency through Cronbach's alpha showed the satisfactory internal stability of the questionnaire. Conclusion: Based on the results of the study, the Persian version of Drive for Muscularity Attitudes Questionnaire has appropriate reliability and validity in Iranian athletes' population and it is an appropriate instrument for screening, and research opportunities in the field of sport psychology.
