Abstract
In a classic study, Rushton and colleagues presented a 20-item scale to assess the altruistic behavior of people: the Self-Report Altruism (SRA) scale. This article focuses on the development of a simplified 9-item scale—the 9-SRA scale—describing the entire refinement and validation procedure using exploratory and confirmatory factor analysis. The 9-SRA shows adequate reliability and validity and represents a more parsimonious instrument to assess altruism and for use in empirical studies focused on human and prosocial behavior. The article discusses the advantages and potential applications of the new scale.
Highlights
Decision sciences, management, consumer behavior, public policy, economics and other disciplines can benefit from its use in a wide variety of areas: organizational citizenship behavior, the production and consumption of public goods, free-riding behavior, vaccination proneness, donations, smoking, drinking, obesity, bullying, and antisocial behaviors
The results presented in this study provide evidence regarding the reliability and validity of the shorter 9-Self-Report Altruism (SRA) scale
Altruism is considered a human characteristic that differentiates us from other species [34]
