The Inventory of Complicated Grief Revised (ICG-R) assesses symptoms of complicated grief in bereaved individuals. The aim of this study was to assess the factorial structure of Complicated Grief (CG) and investigate the relationship between CG and Posttraumatic Stress Disorder through the assessment of models which combine both constructs. A secondary aim was to test the construct validity of the Danish version of ICG-R. The questionnaire was completed by respondents who were elderly and married with a history of at least one significant, interpersonal loss (145 males and 147 females, 60-81 years). Confirmatory factor analysis (CFA) supported a two-factor model (separation distress and traumatic distress) of CG. To investigate the relationship between CG and PTSD three combined models were specified and estimated using CFA. A model where all five factors, the two factors of CG and the three factors of PTSD, as defined by the DSM-IV (American Psychiatric Association, 1994), were allowed to correlate provided the best fit. The results therefore indicate high levels of conceptual overlap among the dimensions of CG and PTSD.
