Abstract
The present study examined the internal and external validity of the French version of the 12-item Disgust Propensity and Sensitivity Scale-Revised (DPSS-12) in a nonclinical sample from the general population. Two hundred and eighty-two participants completed the DPSSf-12 questionnaire as well as the Anxiety Sensitivity Index (ASI), Anxiety Trait (STAI B), Obsessional Belief Questionnaire 44 items (OBQ 44), Obsessive Compulsive Inventory-Revised (OCI-R) and Positive and Negative Affect Schedule (PANAS). Confirmatory Factor Analysis supported a 2-factor structure after two sensitivity items were removed. The 10-item scale showed good internal consistency, construct validity and test-retest reliability. These adequate psychometric properties make the DPSSf-10 appropriate for use by researchers and practitioners.
Highlights
Disgust is recognized as a universal emotion [1, 2], with distinct developmental features, behavioral, physiological dimensions and cognitive biases [3,4,5,6,7,8]
We evaluated external validity and more precisely we hypothesized that disgust propensity (DP) would be more strongly associated with behavioral dimensions of OCD symptomatology as measured by Obsessive Compulsive Inventory-Revised (OCI-R) than disgust sensitivity (DS), and that DS would be more strongly associated with cognitive dimensions of OCD symptomatology as assessed by Obsessional Belief Questionnaire 44 (OBQ-44) and cognitive sensitivity related to anxiety (ASI) than DP
IRB’s number which was assigned is: COS-RGDS2018-10-002-Avis IRB-NOVARA-C. We relied both on a secured online research platform set up by the Epsylon laboratory and paper questionnaires filled in small groups to recruit participants from the general population (187 females, 72 males, 25 did not provide gender, Mage = 31.39; SDage = 13.38 ranging from 19 to 77; 23,1% of whom had a level of education lower than bachelor’s degree and 62% of whom were undergraduate students)
Summary
Disgust is recognized as a universal emotion [1, 2], with distinct developmental features, behavioral, physiological dimensions and cognitive biases [3,4,5,6,7,8]. There is a broad consensus that disgust plays a key role in motivating behavior that reduces exposure to pathogens, and this concept has developed as a mediator of a dynamic adaptive system, a “behavioral immune system”, motivating disease avoidance [10, 11, 12, 13]. Disgust has been shown to be involved in the development and maintenance of several mental disorders including spider phobia [14, 15], contaminationbased Obsessive–Compulsive Disorder (OCD; [16, 17], Blood-Injury-Injection (BII) phobia [18], hypochondriasis [19], Post Traumatic Stress Disorder [20], sexual dysfunctions disorders [21] and eating disorders [22].
