Youth volunteering for at-risk youth can have an impact on the clients' willingness to receive help as well as the youth who volunteer. The current study, undertaken in drop-in centers for youth at-risk in Israel, studied youth volunteers in comparison with adult volunteers as well as the clients of the service. It combined quantitative and qualitative data in order to understand the motivations, benefits and commitment of youth volunteers and to compare these aspects with those of adult volunteers in the same organization. Findings show that youth volunteers have different motivations, benefits and costs than adult volunteers. Youth volunteers are more relationship oriented; adult volunteers are more service oriented; and the volunteer group plays several important roles in youth volunteering. The clients (at-risk youth) perceived the youth volunteers as helpful and described how volunteers their age changed their world view and empowered them to volunteer themselves. In addition, there are blurred boundaries between youth clients and volunteers.
