The teaching personal-social responsibility (TPSR) model is a well-established approach for developing positive social behaviors. However, today's research community has diagnosed the need to gather greater empirical evidence regarding the consistency of the evaluation tool in measuring personal-social responsibility levels. Thus, this study was geared towards testing the validity and reliability of a two factor model of the Personal and Social Responsibility Questionnaire (PSRQ) among athletes. A questionnaire was administered to 517 athletes, distributed into two representative samples of different competitive levels, sports and regions. Exploratory and confirmatory factor analyses were used to examine the PSRQ's factor structure. The scale showed good psychometric properties and the factor structure was stable in the two samples, providing evidence of cross validity. Implications and research directions of these results are discussed.
