Therefore, this study was conducted with the aim of Psychometric properties of mHealth Technology Engagement Index.
Materials and Methods: The present study is psychometric research that was conducted in Tehran University of Medical Sciences in 1401. The participants of this study were 450 students of medical sciences in Tehran in undergraduate, master’s and doctorate levels who were included in the study through convenience sampling. The psychometric characteristics of the questionnaire were examined through face, content and construct validity respectively. Principal component analysis was performed using varimax rotation in order to check the factorial structure of the questionnaire.

The results of exploratory and confirmatory factor analysis extracted five factors, autonomy, competence, relatedness, goal setting and goal attainment, and their cumulative variance was %71.48.  The fit of the five-factor model was optimal based on standard goodness of fit indices such as CFI=0.978, GFI=0.930, RMSEA=0.040, CMIN/DF=1.307. Convergent and divergent validity was accepted for all factors. The reliability of the questionnaire was obtained using Cronbach’s alpha test of 0.71.
