Hypochondriacal fears and beliefs in obsessive-compulsive disorder.

ABSTRACT

The relationship of obsessions and compulsions with hypochondriasis is receiving increasing attention, but has not been substantiated by adequate research. The Illness Attitude Scales (IAS), which identify hypochondriacal patients, were administered to 30 patients with DSM-IV obsessive-compulsive disorder and 30 healthy control subjects matched for sociodemographic variables. All IAS scales were significantly higher in patients with obsessions and compulsions. However, there were no significant differences between patients and controls in the number of subjects whose symptom intensity exceeded a clinical threshold for hypochondriasis and disease phobia. Furthermore, hypochondriacal fears and beliefs were poorly correlated with obsessions and compulsions. The results suggest the presence of mild abnormal illness behaviour in patients with obsessive-compulsive disorder, unlike the situation in patients with panic disorder and depression.
