Religiosity and obsessive-compulsive behavior in Israeli Jews

Individual differences in obsessive-compulsive (OC) behavior in various cultures correlate with religiosity. The current paper explored the so far unstudied relationship between religiosity and OC behavior in Israeli Jews. Two studies were conducted. Study 1 focused on the relationship between religiosity and OC behavior in a representative sample of Israeli students. Study 2 focused on religious change and OC behavior in a non-random sample of 31 individuals who had become more religious (the MR group), and 30 individuals who were less religious (the LR group) than their parents. Instruments used were the Maudsley obsessive-compulsive inventory (MOCI), the student religiosity questionnaire, and questions about parental home observance, upbringing, and changes in religiosity. In the first study, no association was found between religiosity and OC behavior. Religiosity was related to some degree to perfectionism and to the parental attitude to upbringing. In the second study, a significant difference was observed between the MR and the LR groups on OC behavior as measured by the MOCI. Conclusion, among Israeli Jews a lot of religious observance is non-reflective, and is not associated with individual differences in personality or OC symptoms. Those who undergo religious change may do so in response to their behavioral propensities. One such path is that the more OC become MR, and the less OC less religiously observant.
