title: [Meta-analysis of psychosocial interventions to reduce pain in patients with cancer].
abstract: OBJECTIVE
  The purpose of this study was to investigate the effects of psychosocial interventions on pain in cancer patients.
  
  
  METHODS
  Eight studies published between 1980 and 2012 in Korean and ten studies published between 2002 and 2012 in English met the inclusion criteria with a total of 1539 participants. Methodological quality assessed by Cochrane's Risk of Bias for randomized studies and Risk of Bias Assessment tool for non randomized studies. The data were analyzed by the RevMan 5.2 program of Cochrane library.
  
  
  RESULTS
  Overall, study quality was moderate to high. Effect sizes were heterogeneous and subgroup analysis was done. Cognitive behavioral therapy (CBT) were effective for pain (ES= -0.35; 95% CI= -0.56, -0.13). Pain education studies measured with NRS and VAS were effective for pain (ES= -0.77; 95% CI= -1.01, -0.52). Publication bias was not detected.
  
  
  CONCLUSIONS
  This study support the use of psychosocial interventions administered to cancer patients for their pain management. However, more well-designed studies are needed.
