This research examines the patterns of the life course of middle-aged and aged women after they have participated in volunteer activities. In addition, it also analyzes the functions of helper networks and helper-helped relationships in situations requiring the resolution of negative events. The following findings were drawn based on interviews with 21 volunteers and participant observations: 1) As with occupational activities, volunteering provides the opportunities for the target partic-ipants to participate in various social roles outside of their home environments. 2) The helper networks and helper-helped relationships could complement each other in such ways that the helper networks were found instrumental in resolving the negative events that had stemmed from helper-helped relationships, and vice versa.
