Iranian Adolescents Well-Being Scale (IWBS-A): Development and Technical Evaluation

Abstract

The aim of this study was to develop an indigenous instrument to measure the well-being of Iranian adolescents based on the five-factor model of EPOCH (2016). Method: this study is a basic research in terms of descriptive survey method. The population consisted of high school students in Tehran who were selected in two phases, a total of 579 subjects (249 girls and 330 boys) who were randomly selected. In the first phase, after a literature review and selection of the theoretical model, 121 items were selected by experts from the original pool of 576 items. Then, Face validity was performed. In the second phase, item analysis and exploratory factor analysis were performed for a 99-item scale. The results of the item analysis led to the deletion of 10 items. The exploratory factor analysis yielded five components that were consistent with the theoretical model. The results of the parallel analysis also indicated that the items were not randomly ordered and confirmed the results of the exploratory factor analysis. The correlation coefficient of the perseveration components with Procrastination Assessment Scale (PASS) was -0.52, Inventory of School Motivational (ISM) 0.52, and with the Peer Rejection Scale (PRS) -0.26. The internal consistency of the total score and subscales ranged from 0.79 to 0.94. Analyzes were performed with SPSS 20 software. The Adolescent Well-Being Scale has good psychometric properties, so it can be used for research purposes.
