Findings of a confirmatory factor analysis (Study 1), and tests of internal consistency and test-retest reliability (Study 2), concurrent validity (Study 3), convergent, and discriminant validity (Study 4), have been presented in this article. The confirmatory factor analysis conducted in Study 1 indicated that the unidimensional-factor structure had the best fit to the data. Study 2 found that the internal consistency value was acceptable and test-retest reliability over a 4-week period was adequate. Study 3 supported the concurrent validity of the Turkish PBIS with reference to altruism and empathy. In Study 4, convergent validity was established based on the correlation between the Adult Prosocialness Scale (APS) and Turkish PBIS. Factor loadings and t-values of the items, composite reliability (CR), and the Average Variance Extracted (AVE) value of the Turkish PBIS were optimal. Discriminant validity was confirmed based on the correlation between the Turkish PBIS and Social Appearance Anxiety Scale (SAAS), with adequate cross-loadings of the PBIS and the Fornell and Larcker criterion. Thus, the Turkish PBIS was found to be a brief, valid, and reliable measure of prosocial behaviors.eninfo:eu-repo/semantics/closedAccessProsocial behavioral intentionsAdaptationValidationTurkish cultureArticle10.1007/s12144-019-00277-y384950958WOS:000481760100007Q2Q2
