title: Systematic review of peer-support programs for people with cancer.
abstract: OBJECTIVE
  To identify models of peer support for cancer patients and systematically review evidence of their effectiveness in improving psychosocial adjustment.
  
  
  METHODS
  CINAHL (Cumulative Index to Nursing and Allied Health Literature), MEDLINE and PsychINFO databases were used to identify relevant literature published from 1980 to April 2007. Data on characteristics of the peer-support program, sample size, design, measures, and findings were extracted and papers were also rated with respect to research quality (categories 'poor', 'fair' or 'good').
  
  
  RESULTS
  Forty-three research papers that included data from at least 1 group were reviewed in detail, including 26 descriptive papers, 8 non-randomized comparative papers, and 10 papers reporting eight randomized controlled trials (RCTs). Five models of peer support were identified: one-on-one face-to-face, one-on-one telephone, group face-to-face, group telephone, and group Internet.
  
  
  CONCLUSIONS
  Papers indicated a high level of satisfaction with peer-support programs; however, evidence for psychosocial benefit was mixed.
  
  
  CONCLUSIONS
  One-on-one face-to-face and group Internet peer-support programs should be given priority when considering ways to offer peer support. Nevertheless, the other models discussed in this review should not be dismissed until further research is conducted with a wide range of cancer populations.
