Le dégoût dans le trouble obsessionnel compulsif, mécanismes, évaluation, implications pour des pistes thérapeutiques

Abstract

IntroductionAlthough considered a basic emotion, disgust has received little attention from research from the psychology of emotions compared to other emotions such as fear or sadness. Literature findingsMany empirical and experimental data suggest, however, that disgust plays a determining role not only in our ability to adapt to our environment but also in the maintenance and development of certain psychopathological states such as obsessive-compulsive disorders. The purpose of this article is to review the literature on the construct of disgust, including its two basic dimensions of disgust and disgust. A first part will be dedicated to the acquisition of disgust in the framework of evaluative and Pavlovian learning, we will then describe in detail the assessment tools available in the literature allowing to evaluate the different dimensions, then we will address the continuum. Experience of disgust, from normal disgust to pathological disgust, and will particularly target its role in dysfunctional obsessions of contamination and emotional distress. DiscussionIf, from a theoretical point of view, the understanding of the underlying mechanisms of pathological disgust reactions improves, the proposals for treatment to mitigate these reactions are rare. New approaches to care will be described to allow the development of empirically based psychological interventions. ConclusionThe recognition of emotional influences beyond anxiety in obsessive-compulsive disorder (OCD) stems from the fundamental importance of a dimensional approach to psychopathology and support. The accumulated data suggest that the inclusion of disgust in the theoretical models of OCD, in particular those with contamination concern, will thus improve our understanding and treatment of this disorder.
