A German Adaptation of the Prosociality Scale

Abstract

Abstract. Introduction: This paper presents a German translation of the 16-item Prosociality Scale. We analyzed its factor structure based on theoretical assumptions regarding the inclusion of empathy as one element of prosociality or as its underlying construct. Methods and Results: We translated the items into German taking into account both the English and the Italian item wordings. The scale's factor structure was analyzed with three models testing (1) unidimensionality, (2) a four-factor structure with four items on each factor, and (3) a variant of a bifactor model with a general factor including all items and three residual factors with four items each. We analyzed construct validity using the Interpersonal Reactivity Index. Finally, we identified two 13-item versions with good model fit. Conclusion: The German Prosociality Scale is not unidimensional. Empathy seems to be the underlying construct of prosociality, but it can also be considered an element of prosociality.
