Denial as a defense against depression in end-stage renal disease: an empirical test

End-stage renal disease (ESRD) is recognized as imposing severe psychosocial stresses upon patients with the result that depression is believed to be highly prevalent. A number of studies have reported low levels of depression, however, and this contradictory finding has been explained via the construct of defensive denial-i.e., patients may minimize the impact of illness-related experiences upon their overall experiences of life. The present study tested this hypothesis in a sample of seventy ESRD patients. Participants rated a series of twelve life dimensions (e.g., work, family and martial relations, recreation) in terms of perceived intrusiveness and control as well as indicating their perceived similarity using a card sort task. Standard measures of depression, positive and negative moods, somatic symptoms of distress, self-esteem, and life happiness were also obtained via structured interviews. A multidimensional scaling analysis applied to the card sort data indicated that ESRD patients do, indeed, perceive illness-related and nonillness aspects of life as independent. However, an analysis of partial variance-controlling for age and nonrenal health-failed to provide evidence of defensive denial. The suggestion is forwarded that previous findings of a high prevalence of depression in ESRD may be in error due to the misidentification of uremic symptoms as symptoms of depression.
