Abstract

Contamination aversion is implicated in a range of psychological disorders, such as obsessive-compulsive disorder and health anxiety. Despite broad implications, the core mechanisms mediating contamination aversion are mixed and have not clearly been elucidated. The present studies are psychometric investigations of the components of contamination aversion and tests of the different mechanisms that mediate the severity of these components. In Study 1, items from existing measures of contamination aversion were compiled into one measure and administered to a large sample of nonclinical participants (N = 1,286). Exploratory factor analyses demonstrated a two-factor structure, with one factor comprised of items related to intrinsically (direct) contaminated objects and the other factor comprised of items related to extrinsically (indirect) contaminated objects. In Study 2, items were added and confirmatory factor analyses supported a two-factor model in another large nonclinical sample (N = 612). In Study 3 (N = 471), structural modeling demonstrated distinct relations between the two factors and affective and cognitive constructs. Affective constructs related more to aversions toward more directly contaminated objects and situations while cognitive constructs related more to aversions toward more indirectly contaminated objects and situations. The present studies help clarify and articulate the unique roles of cognition and affect in specific contamination aversions, and, as such, have important implications for conceptual modeling of contamination-related psychopathology.
