Emotional responsiveness and obsessive-compulsive behaviour

Abstract

Several clinicians have proposed that patients with obsessive-compulsive disorder (OCD) are unusually sensitive to unpleasant events. We tested a non-clinical sample of obsessive-compulsive (O-C) subjects who reported in diagnostic interviews that they experienced significant problems with obsessions and/or compulsions. Excerpts from three emotion-eliciting films were shown to 10 O-C males, 12 O-C females, 12 normal males, and 12 normal females. Emotional response was measured by using a self-report instrument and by recording facial expressions, which were coded for both appropriate emotional reactions as well as reactions that may represent efforts to mask or control the display of negative emotion. The groups did not differ with regard to subjective response to the film clips, but facial responses indicated that O-C subjects made more efforts to suppress the expression of fear (inappropriate smiles/laughs) during the frightening film clip. In spite of these responses, male O-C subjects also tended to reveal more frightened facial expressions than male control subjects. This finding is believed to illustrate one component of a model in which exaggerated emotional response is a precursor to the development of OCD.
