To estimate the correlation between scores on obsession-compulsion and both age and sex, two studies were carried out with Kuwaiti (n1 = 87, n2 = 460), and American (n1 = 73, n2 = 273) undergraduates. The Arabic Obsessive-Compulsive Scale was used in both studies. Significant correlations were found for the Kuwaiti sample; however, these correlations were of low magnitude and have no practical value.
