This study explored the role of volunteers' psychological capital and family concern in the effect of the authentic leadership and organization's climate on volunteering behavior in volunteer organizations. A questionnaire survey was used to investigate 945 college student volunteers from volunteer organizations in Chinese colleges at three time points. The results found that authentic leadership and the climate in the volunteer organization were significantly and positively related to volunteers' psychological capital and volunteering behavior, and family concern was significantly and positively related to authentic leadership in volunteer organizations and volunteers' psychological capital. Authentic leadership and climate in volunteer organizations positively affected volunteering behavior, not only directly but also indirectly, through the mediating role of volunteers' psychological capital. Moreover, family concern played a moderating role in the indirect effect of authentic leadership and the climate in volunteer organizations on volunteering behavior through volunteers' psychological capital. Specifically, when the college students' family concern increased, the positive indirect effect of the authentic leadership and climate in volunteer organizations on volunteering behavior through volunteers' psychological capital increased.
