Volunteer Behavior: A Hierarchical Model Approach for Investigating Its Trait and Functional Motive Antecedents

We investigated the antecedents of volunteer behavior within a hierarchical model of motivation and personality. In Study 1, we developed measures of altruism and volunteer orientation and combined them with three additional traits to predict a set of volunteer behaviors. In Studies 2 and 3, we added six functional motives for volunteering identified by Clary et al. (1998) to the model. Across the 3 studies, the traits of altruism, the need for activity, and the need for learning were consistent predictors of volunteer orientation. In Studies 2 and 3, the measure of volunteer orientation was a significant predictor of the functional motives and of volunteer behaviors. Furthermore, the motive to help others was positively related to volunteering behaviors, and the motive of self-enhancement was negatively related to them. Overall, the results support the proposal that functional motives act like motivated reasons for acting and reside at the surface level in a hierarchical model of personality.
