Obsession-compulsion, locus of control, depression, and hopelessness: a construct validity of the Arabic Obsessive-Compulsive Scale in American and Kuwaiti students.
In samples of 144 American and 209 Kuwaiti college students, the correlations among scores on the Arabic Obsessive-Compulsive Scale and external locus of control (.26, .25), depression (.31, .55) and hopelessness (.27, .43) were significant and positive in both samples, denoting the construct validity of the Obsessive-Compulsive Scale. Thus, it can be recommended for use in both countries.
