title: Validation of a decision regret scale.
abstract: BACKGROUND
  As patients become more involved in health care decisions, there may be greater opportunity for decision regret. The authors could not find a validated, reliable tool for measuring regret after health care decisions.
  
  
  METHODS
  A 5-item scale was administered to 4 patient groups making different health care decisions. Convergent validity was determined by examining the scale's correlation with satisfaction measures, decisional conflict, and health outcome measures.
  
  
  RESULTS
  The scale showed good internal consistency (Cronbach's alpha = 0.81 to 0.92). It correlated strongly with decision satisfaction (r = -0.40 to -0.60), decisional conflict (r = 0.31 to 0.52), and overall rated quality of life (r = -0.25 to -0.27). Groups differing on feelings about a decision also differed on rated regret: F(2, 190) = 31.1, P < 0.001. Regret was greater among those who changed their decisions than those who did not, t(175) = 16.11, P < 0.001.
  
  
  CONCLUSIONS
  The scale is a useful indicator of health care decision regret at a given point in time.
