In two samples of 87 Kuwaiti and 73 American undergraduates, scores on the Arabic Obsessive-Compulsive Scale correlated .71 and .63 with those on another obsession scale, respectively, while they correlated .49 and .19 with scores on a depression scale. The differences between these correlations in the two samples indicated good convergent and discriminant validity of the Arabic Obsessive-Compulsive Scale in both cultures.
