Charity- and project-based service learning models increase public service motivation outcomes among dietetic students in a community nutrition course.

Abstract

To determine whether dietetic students would report a change in their public service motivation (PSM) following a community nutrition service learning (SL) course, and whether the SL model (charity v. project) influences this change differently. Using a pretest-posttest, nonequivalent groups quasi-experimental design, this study compared students' PSM at the beginning and end of a 15-week college-level course. PSM and four component dimensions (attraction to public policy, commitment to public interest, compassion and self-sacrifice) were measured via electronic survey using the PSM scale. Average PSM scores were compared between and within the charity and project groups using independent samples and paired sample t tests, respectively. ANCOVA assessed the effect of SL model on post-survey scores, controlling for pre-survey scores. Public university in northeastern United States. Dietetic students enrolled in six sections of the same undergraduate community nutrition SL course. Students were placed by section in either charity (n 59) or project (n 52) SL experiences and required to complete 14 h in this role. Mean PSM total scores increased between pre-survey and post-survey (3·50 v. 3·58; P = 0·001). Students reported small increases in three PSM dimensions: commitment to public interest, compassion and self-sacrifice (all P ≤ 0·01). Holding pre-scores constant, the charity group reported a higher attraction to public policy post-score, while the project group reported a higher self-sacrifice post-score (both P < 0·05). Educators should consider adopting SL methods into curricular offerings to enhance students' motivation for public service.
