title: Quality assessment of randomized control trials applied psychotherapy for chronic pains in iran: a systematic review of domestic trials.
abstract: BACKGROUND
  Keeping in mind the burden of psychotherapy can play a crucial role concerning chronic pain (CP). Psychotherapy techniques are widely used to relief Chronic Pain (CP) worldwide. Appling psychotherapy needs to consider both individual and popular cultures. In addition to international requirements; nation-wide legitimacy should be regarded too. Psychological methods have provided a lot of articles in Iran, but they were neglected by the reviewers because the documents only have abstracts in English. The current study aimed to assess all Farsi Randomized Control Trials (RCTs) addressing psychotherapy to relieve chronic pains.
  
  
  METHODS
  Six nation-wide medical databases were investigated in 2012 using the keyword chronic pain in the Abstracts, systematically. Appling PICO question format (patient problem or population, intervention, comparison, and outcomes) all the interventional studies were reviewed for eligibility. Retrieving full text (in Farsi) and making the articles indistinguishable, two native reviewers assessed the quality of the articles independently using Jadad scale.
  
  
  RESULTS
  Inclusion criteria met 1542 abstracts. After refining and excluding, seventeen experimental studies were retrieved and evaluated. Mean quality score of Jadad was 1.53 ± 1.37 (median = 1.0). Cognitive Behavior Therapy (CBT) was the dominant approach (11 out of 17) and the majority (6 out of 17 studies) of the treated cases was Low Back Pain (LBP). Patient-therapist gender adjustment has clearly reported in most of the studies, based on the requirements.
  
  
  CONCLUSIONS
  Cognitive Behavior Therapy was more effective than the other psychotherapy approaches relieving chronic pain in the studies. Well-designed studies and comprehensive clarification of the studies demonstrating groups, intervention, follow-up and drop outs can improve the quality of the RCTs.
