Some of indices which are provided for measurement of life quality in general population are not applicable for all groups such as children and individuals with cognition disorders. In order to cope with this limita-tion, after some researches, personal welfare (life quality) index (PWI) was developed in Australia. Subsequently, its similar version was de-signed for student population of 12-year to 18 year old and its psycho-metric features was evaluated. So, the purpose of this study is examina-tion of the mentioned scale psychometric features among Iranian student population. Statistical population was all of high school students in Boj-nourd. A sample of 563 students was selected by cluster sampling. In this study, Personal Welfare Index Student Copy (PWI-SC), General health Questionnaire (GHQ-28), and Generalized Anxiety Disorder 7-item (GAD-7) were used. Also, Pearson correlation, confirmative heuris-tic factor analysis, regression and t-test for independent groups were ap-plied. Findings showed that PWI-SC based on Cronbach Alpha (0.81), two-item scale Cronbach Alpha (0.69 and 0.62), and correlation coeffi-cient related to its retest (0.87) have appropriate reliability. Also, relia-bility of scale was evaluated by correlation to other questionnaires: GHQ and GAD-7. Factor analysis of the scale in Iranian student sample indi-cates its saturation by one factor. Generally, personal welfare index stu-dent copy (PWI-SC) has appropriate psychometric features considering the methodology limitations of this study.
