title: Complicated grief, depression, and anxiety as distinct postloss syndromes: a confirmatory factor analysis study.
abstract: OBJECTIVE
  The authors used confirmatory factor analysis to replicate earlier findings that complicated grief, depression, and anxiety are distinct syndromes.
  
  
  METHODS
  Data were derived from 1,321 bereaved individuals. Complicated grief was measured with the Inventory of Traumatic Grief. Depression and anxiety were measured with the SCL-90.
  
  
  RESULTS
  A model in which symptoms of complicated grief, depression, and anxiety loaded on separate factors was superior to a one-factor model, revealed good model fit, and was invariant across subgroups.
  
  
  CONCLUSIONS
  Previous findings of a distinction among complicated grief, depression, and anxiety were confirmed.
