Little research has examined the effects of service participation and the level of integration of service into courses on alumni service-related attitudes and behaviors. In the present study, 481 alumni of a religious-affiliated liberal arts college participated in a phone survey that examined their present and past behaviors related to service and their current service-related attitudes. Results showed that participation in both general community service and service-learning as undergraduates was positively associated with alumni attitudes toward social and personal responsibility as well as alumni involvement in post-college community service and service-related careers. Service-learning participation exerted an effect over and above that accounted for by community service participation. Positive relationships of service-learning with outcomes generally were limited to courses that provided high-quality experiences (more hours of service, more reflection activity, and more integration of service into the course).
