For the purposes of study, the questionnaire was translated. At first stage of the psychometric evaluation, content validity of the questionnaire was measured by Waltz and Bussel content validity index. In order to the evaluating reliability, for determining the external stability of this instrument, test-retest and inter class correlation coefficient were used and for determining the internal consistency, Cronbach's alpha coefficient was used. Construct validity indexes were calculated using confirmatory factor analysis.Results: Findings showed that internal correlation coefficient (Alpha Cronbach) was 0.95 for 'health promotion lifestyle profile 2’. Inter class correlation coefficient for the instrument subscales were between 0.67-0.87. Confirmatory factor analysis to assess the validity of the index, fitted χ2 was equal to 2.58, the RMSEA index was equal to 0.05, GFI index equal to 0.83, and CFI index was equal to 0.95, respectively.Conclusion: There is high correlation between the total score of "Health promotion lifestyle profile 2" and its subscale scores.
