The purpose of this study was to review the previous studies to examine the evidence for self-help groups for cancer survivors. The search strategy began with 5 electronic databases such as PsycARTICLES (2000-2011), CancerLit (2000-2011), PubMed (2000-2011), PsycINFO (2000-2011), and CiNii (Citation Information by NII, 2000-2011). A total of 27 scientific literatures were included with no psychological research, in which most were nursing researches. The authors discussed three issues: the method of the research, the difference between support group and self-help group, and the evidence of the self-help group, and then stressed the importance of researches using quantitative methods and researches conducted by the survivors themselves
