title: Enhancing informed choice to undergo health screening: a systematic review.
abstract: OBJECTIVE
  To assess the effectiveness of health screening interventions aimed at enhancing informed choice.
  
  
  METHODS
  Studies were selected if (1) they were randomized controlled trials conducted between January 1, 2000, and March 30, 2010, (2) participants in one arm underwent a prescreening intervention aimed at improving informed choice, and (3) informed choice was the primary outcome.
  
  
  RESULTS
  Eight studies that met the inclusion criteria involved screening for prostate, colorectal and breast cancer, and diabetes. Five of the 8 prescreening interventions led to greater informed choice.
  
  
  CONCLUSIONS
  With researchers mindful of the limited number of studies, findings were encouraging, but conclusions regarding the most effective ways of facilitating informed choice for screening are at best tentative.
