title: Depression and abnormal illness behavior in cancer patients.
abstract: Evaluation of the incidence of depression among cancer patients has been the object of a number of studies. Recent reports of medically ill patients have indicated that depression is related to several dimensions of abnormal illness behavior (e.g., hypochondriasis, irritability, denial, disease conviction). To investigate the relationship between depression and abnormal illness behavior in cancer patients, a study was conducted of 196 patients with a recent diagnosis of cancer and with a good performance status (Karnofsky score greater than 80). The Hamilton Depression Rating Scale (HDRS) and the Illness Behavior Questionnaire (IBQ) were administered in their validated Italian forms. A cutoff point of 17 on the HDRS revealed 38.26% of the patients as having symptoms of depression, whereas a more conservative cutoff point of 21 indicated a depressive state in 23.97% of the patients. Depressed patients had higher scores on all the IBQ dimensions except that of psychologic versus somatic perception of illness. The results were confirmed by the correlation between the parameters. Higher levels of denial were reported by females and by patients receiving adjuvant or palliative chemotherapy, who had, however, lower levels of dysphoria than patients not receiving treatment. Higher levels of irritability were shown in hospitalized patients. No relationship was found between medical status variables (Karnofsky score, tumor status, and disease extent) and psychologic measures, except for denial. The findings seem to confirm the importance of assessment of depression and illness behavior in cancer patients and suggest the need for more thorough investigation of the psychosocial variables associated with them.
