In this article we test whether reasons to quit volunteering can be structured as the commonly used six functional motives to volunteer of Clary et al. (1998). We conjecture that owing to volunteer involvement in an organization, additional contextual factors influence the choice to stop volunteering for that organization. Based on a literature review and a qualitative exploratory analysis, we present items respectively measuring motives to volunteer among active volunteers and reasons to quit among former volunteers in the context of the Scouts and Guides Organization in Flanders (Belgium). We test content-wise symmetry based on expert-rater agreement, while structural symmetry is tested based on factor analyses. Results show that no symmetry can be found. However, additional contextual factors clearly determine the decision to leave an organization. We theorize on how these individual, interpersonal and organizational factors are continuously traded off by volunteers during their involvement in a particular organization.
