Pro-Social Behavior Scale (PSBS) Development Study

In this study, it was aimed to develop a measurement tool to measure the prosocial behaviors of adolescents. The research was carried out on 540 students studying at secondary and high school levels in Istanbul and Küçükçekmece districts. After the exploratory factor analysis, it was observed that the scale consisted of 4 sub-dimensions: empathy, altruism, sympathy and self-worth. The theoretical structure of these four dimensions of the scale was supported by confirmatory factor analysis. The variance explained by all items of the scale was measured as 66.75. In order to support the validity level of the scale, it was observed that the correlations between the item discrimination values of the items calculated with the t-test and the subscale scores were significant. The external validity of the scale was compared with the previously developed prosocial behavior scale and significant relationships were found between them. Cronbach Alpha values were calculated for the reliability study of the scale, and it was observed that the reliability values of the scale, including the total scale scores, ranged between .74 and .91. In the light of the psychometric data obtained as a result, a measurement tool with high reliability and validity values was developed for adolescents.
