Boelen, P. A., & Bout, J. van den (2005). Complicated grief, depression, and anxiety as distinct post-loss syndromes: A confirmatory factor analysis study . American Journal of Psychiatry, 162, 2175-2177.
OBJECTIVE: The authors used confirmatory factor analysis to replicate earlier findings that complicated grief, depression, and anxiety are distinct syndromes. METHOD: 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.
