Identification and explanation of racial differences on contamination measures.
Compared with published norms, African Americans endorse significantly more items intended to assess pathological anxiety about contamination on self-report instruments for obsessive-compulsive disorder. The current study suggests that this is not due to greater psychopathology in African Americans, but rather to differences in normal attitudes about cleanliness that also influence responses to items intended to assess anxiety pathology. Contamination items from obsessive-compulsive disorder (OCD) scales including the Padua Inventory [Sanavio E. (1988). Obsessions and compulsions: The Padua Inventory. Behaviour Research and Therapy, 26(2), 169-177] were supplemented with cleanliness attitude items and administered to Black and White participants (N=1483). An exploratory factor analysis suggested a three-factor solution: one factor that encompassed pathological anxiety, and two that expressed attitudes about cleanliness, grooming, and domestic animals. African Americans scored significantly higher on all three factors. A confirmatory factor analysis demonstrated that the difference between Black and White participants on the pathological anxiety factor was eliminated when differences on the attitude factors were controlled statistically.
