Factorial Validity of the Arabic Obsessive-Compulsive Scale in Two Cultures

The Arabic Obsessive-Compulsive Scale and the Maudsley Obsessional Compulsive Inventory were administered to 87 Kuwaiti (Arabic version) and 73 American college students (English form). Pearson correlations for the total score on the Arabic scale and the four subscores of the Maudsley scale: Checking, Cleaning, Slowness, and Doubting were .72, .48, .50, and .61 for the Kuwaitis and .52, .40, .51, and .52 for the Americans. The loadings of the total score of the Arabic scale onto a factor of obsession and compulsion were .83 and .79 for Kuwaiti and American students, respectively, denoting a good factorial validity of the Arabic scale.
