Developing an implicit measure of disgust propensity and disgust sensitivity: Examining the role of implicit disgust propensity and sensitivity in obsessive-compulsive tendencies

Background and objectives: There is increasing evidence that disgust responding occurs at both a primary and secondary level in the form of disgust propensity and disgust sensitivity. The unique contributions of anxiety and disgust need to be established if disgust is to be implicated in the etiology of anxiety disorders such as obsessive-compulsive disorder (OCD). The primary objective of the current study was to develop two separate implicit measures of disgust propensity and sensitivity and to explicate the role of implicit disgust propensity and sensitivity in avoidance behavior and OC tendencies. Methods: The current study (N = 33 undergraduate students) utilized a measure of implicit cognition, the Implicit Relational Assessment Procedure (IRAP), to independently analyze disgust propensity and disgust sensitivity. In addition, a series of behavioral approach tasks (BAT) and questionnaires measuring general disgust, obsessive-compulsive (OC) tendencies and general psychopathology were implemented to validate the implicit measures. Results: Disgust sensitivity predicted avoidance behavior on the BATs independent of disgust propensity and anxiety: while disgust propensity did not. Both disgust propensity and sensitivity predicted self-reported OC tendencies and individually predicted obsessing and washing concerns, respectively. Limitations: Our findings are based on a non-clinical student sample and further research is required for generalization to OCD. Conclusions: The implicit measures appeared to be measuring two separate constructs and had differential relationships with behavior and OC tendencies. Overall, the results support current theories relating to pathological disgust and OCD. (c) 2012 Elsevier Ltd. All rights reserved.
