Abstract

The objective of the current research was to validate the Brief Strength Test within Iranian society. This research was descriptive and correlational in nature. The statistical population consisted of the parents of primary school pupils in Yazd City during the 2021-2022 academic year. The sample size was determined to be 300 individuals selected through cluster sampling; ultimately, 286 participants (224 mothers and 62 fathers) completed the questionnaires. Research assessments comprised the Brief Strength Test (BST), the Coping with Children’s Negative Emotions Scale (CCNES), and the Difficulties in Emotion Regulation Scale (DERS). Internal consistency coefficient, convergent validity, divergent validity, and confirmatory factor analysis were employed. SPSS Version 26 and AMOS were employed to conduct the data analysis. The results of the exploratory factor analysis indicated that the BST possesses a unidimensional structure. Additionally, the findings of the confirmatory factor analysis demonstrated that the six-component model provided an acceptable fit (RMSE = 0.061; GFI = 0.99; AGFI = 0.95; NFI = 0.99; IFI = 0.99; CFI = 0.99). The Cronbach’s alpha coefficient for the overall BST score was 0.93, while the subscales ranged from 0.60 to 0.78. The results of the study validated the convergent and divergent validity of the BST. In general, it can be asserted that BST possesses adequate validity and reliability for assessing character abilities within Iranian society.
