Peer volunteers provide valuable support to foster parents. However, there has been limited research on what they consider to be valuable preparation for the role. In the present study, they were asked: "What is essential training for peer support volunteers to receive before starting?". Fifteen participants grouped 41 different responses that were analyzed using multidimensional scaling and cluster analyses. The resulting concepts included: (a) self-care, (b) effective use of self, (c) policies and procedures, (d) finding information and (e) how to address common challenges.
