Mutual aid as group work technology can be understood as an exchange of help wherein the group member is both the provider as well as the recipient of help in service of achieving common group and individual goals (Borkman, 1999; Gitterman, 2006; Lieberman, 1983; &amp; Kurland, 2001; Schwartz, 1961; Shulman, 2006, Steinberg, 2004; Toseland &amp; Siporin, 1986). The rationale for cultivating mutual aid in the group encounter is premised on mutual aid's resonance with humanistic values and the following propositions: 1) members have strengths, opinions, perspectives, information, and experiences that can be drawn upon to help others in the group; 2) helping others helps the helper, a concept known as the helper-therapy principle (Reissman, 1965) which has been empirically validated (Roberts et al., 1999); and 3) some types of help, such as confrontation, are better received when emanating from a peer rather than the worker (Shulman, 2006).
