Abstract Background and Aim: The purpose of the present study was to obtain validity and reliability of the form B of Multidimensional Health Locus of Control scales in Iran. Health locus of control is one of the most widely measured parameters of health belief for the planning of health education programs. Materials and Methods: 496 university students participate in this study. The reliability coefficients were calculated in two different methods: test- retest, parallel tests and Cronbach alpha. In order to survey validity of the scale we used three methods including content validity, concurrent validity and construct validity. Results: The concurrent validity of the questionnaire, as measured by Levenson’s IPC scale was.57 (P<.001), 0.51 (P<0.01) and 0.53 (P<0.01) for IPC, respectively. Confirmatory factor analysis confirmed a three-factor structure (internal, chance and powerful others). Subsequent exploratory principal components analysis supported a three-factor structure that items loading adequately on each factor. Also, supporting the construct validity claim that these dimensions were more-or-less orthogonal to one another. In addition, the reliability of this scale was estimated through test-retest, parallel forms, and Cronbach's coefficient methods. Conclusion: The results showed that reliability and validity of Persian Form B of MHLC was acceptable and respectable.
