New spirituality has often been accused of being egocentric and thus lacking incentives for social engagement. The discussion on this subject is tangled because authors differ in specifying who they are writing about and what the criticism is. After seeking an adequate demarcation of the target group (people involved in new spirituality), we established a concept of social engagement that distinguishes between behavior that is and that is not driven by egocentric motivation. Using measures based on this conceptual model, we surveyed a representative sample of the Dutch population. We found that on most measures people involved in new spirituality are less socially engaged than affiliated or traditionally religious people but more engaged than “secular” people. However, they are more committed to organizations for environmental protection, peace, or animal rights than others. Overall, demographic factors—especially education, age, and gender—are stronger predictors for social engagement than religious and spiritual beliefs, experiences, or practices. The most important spirituality variable that predicts some social engagement measures is connectedness with self, others, and nature.
