The Development and Validation of the Motives to Donate Scale

In this article, we develop and validate a comprehensive self-report scale of why people make charitable donations, relying on a theoretical model of private versus public benefits to donors. In Study 1, we administered an initial pool of 54 items to a general adult sample online. An exploratory factor analysis supported six final factors in the Motives to Donate scale: Trust, Altruism, Social, Tax benefits, Egoism, and Constraints. We then verified this factor structure in a confirmatory factor analysis. Study 1 also examined the final 18-item scale's demographic correlates and construct validity using the same sample. We found that the scale correlated in predictable ways with personality traits and motives to volunteer. In Study 2, we also found test-retest correlations between .67 and .80 after 2 weeks. Taken together, we provide initial evidence for the scale's internal reliability, test-retest reliability, and validity, and we suggest future directions for research.
