Measuring Prosocial Behaviors: Psychometric Properties and Cross-National Validation of the Prosociality Scale in Five Countries.

This research investigated the psychometric properties of the Prosociality Scale and its cross-cultural validation and generalizability across five different western and non-western countries (China, Chile, Italy, Spain, and the United States). The scale was designed to measure individual differences in a global tendency to behave in prosocial ways during late adolescence and adulthood. Study 1 was designed to identify the best factorial structure of the Prosociality Scale and Study 2 tested the model's equivalence across five countries (N = 1,630 young adults coming from China, Chile, Italy, Spain and the United States; general Mage = 21.34; SD = 3.34). Findings supported a bifactor model in which prosocial responding was characterized by a general latent factor (i.e., prosociality) and two other specific factors (prosocial actions and prosocial feelings). New evidence of construct validity of the Prosociality Scale was provided.
