title: An empirical examination of the stage theory of grief.
abstract: BACKGROUND
  The stage theory of grief remains a widely accepted model of bereavement adjustment still taught in medical schools, espoused by physicians, and applied in diverse contexts. Nevertheless, the stage theory of grief has previously not been tested empirically.
  
  
  OBJECTIVE
  To examine the relative magnitudes and patterns of change over time postloss of 5 grief indicators for consistency with the stage theory of grief.
  
  
  METHODS
  Longitudinal cohort study (Yale Bereavement Study) of 233 bereaved individuals living in Connecticut, with data collected between January 2000 and January 2003.
  
  
  METHODS
  Five rater-administered items assessing disbelief, yearning, anger, depression, and acceptance of the death from 1 to 24 months postloss.
  
  
  RESULTS
  Counter to stage theory, disbelief was not the initial, dominant grief indicator. Acceptance was the most frequently endorsed item and yearning was the dominant negative grief indicator from 1 to 24 months postloss. In models that take into account the rise and fall of psychological responses, once rescaled, disbelief decreased from an initial high at 1 month postloss, yearning peaked at 4 months postloss, anger peaked at 5 months postloss, and depression peaked at 6 months postloss. Acceptance increased throughout the study observation period. The 5 grief indicators achieved their respective maximum values in the sequence (disbelief, yearning, anger, depression, and acceptance) predicted by the stage theory of grief.
  
  
  CONCLUSIONS
  Identification of the normal stages of grief following a death from natural causes enhances understanding of how the average person cognitively and emotionally processes the loss of a family member. Given that the negative grief indicators all peak within approximately 6 months postloss, those who score high on these indicators beyond 6 months postloss might benefit from further evaluation.
