The factorial structure of the Arabic Obsessive-Compulsive Scale in Kuwaiti and American college students

Kuwaiti (n=204) and American (n=137) undergraduates responded to the Arabic Obsessive-Compulsive Scale in Arabic and English languages, respectively. Based on the scree test, a principal components (principal axis) factor analysis with an Oblimin rotation yielded three factors in both samples. The factors were labeled (1) obsessive thoughts, (2) orderliness, and (3) checking for the Kuwaiti sample, and (1) obsessive thoughts, (2) orderliness and checking, and (3) lack of obsession for the American sample. By and large, there was good similarity between the first two factors only.
