Abstract

Background: Recent surveys estimated that prevalence rates of obsessive-compulsive disorder were (OCD) more than those estimated by earlier surveys. Moreover, in the general non-clinical population, many studies found high incidence of obsessions and compulsions (OC).

Objective: To develop and validate a revised version of the Arabic Scale of Obsession-Compulsion (ASOC) as a trait scale, suitable for research studies.

Methods: A Sample of 150 non-clinical undergraduates was recruited. The latest version of the revised ASOC is comprised of 20 short statements, plus five filler items. Three subscales of OC were used as criteria from the MMPI, and the Symptom Checklist, (SCL), as well as the Obsessive-Compulsive Inventory (OCI).

Results: Cronbach alpha reliabilities reached .882 (men), .910 (women), and .897 (total group). The correlation coefficients of the ASOC with the MMPI, SCL, and OCI scales were .759, .783, and .885, respectively. A principal component analysis retained one high–loaded factor labeled “Obsession-compulsion:. The loading of the ASOC onto this factor was .948, indicating very high factorial validity.

Conclusion: The ASOC has good psychometric characteristics, i.e., high internal consistency and concurrent and factorial validities.
