Obsessive-Compulsive Symptomatology, Religiosity Levels and the Illusion-of-Control Paradigm in a Non-Clinical Undergraduate Sample.

The present research employed the illusion-of-control paradigm to investigate the relationships between Obsessive-Compulsive disorder (OCD) symptoms, religiosity levels, and illusory sense of control (SC). An opportunistic sample of 60 undergraduate students was presented with a pre-programmed series of neutral visual stimuli (i.e. lines) and was expected to try to control the sequence through the use of keyboard presses. Participants assessed their perceived level of control twice throughout the computerised task. In addition, the study was interested at examining the relationship between religiosity and OC behaviour and the Santa Clara Strength of Religious Faith Questionnaire (SCSRF) was employed. In proportion to predictions, OCD symptoms were correlated with higher illusory SC; furthermore, religiosity levels were related to some degree to OCD symptoms. The essential role of mental control in OCD is discussed, particularly the significant clinical implications of such an association. Furthermore, the possible contribution of religious affiliations to the maintenance of OC behaviour is further discussed.
