The results were analyzed by principal component analysis with varimax rotation and confirmatory factor analysis and the final form of 60 questions was developed. In the second stage, this form was implemented in a sample of 1651 people (791 males and 860 females) and its validity was calculated by validity coefficients of the criterion (convergent and divergent validity). through correlation with Ryff Psychological Well-Being Scale (RSPWB) and Goldberg General Health Questionnaire (GHQ), respectively, and its reliability was calculated by Cronbach's alpha internal consistency and split-half methods.
