Disgust sensitivity and obsessive-compulsive symptoms in a non-clinical sample

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• Obsessive-compulsive disorder (OCD) is a mental health condition characterized by obsessions and compulsions.
• Disgust sensitivity has been theorized to contribute to OCD, but empirical evidence remains inconsistent.
• Understanding the specific links between disgust and OCD symptoms is crucial for targeted interventions.

Purpose of the Study:

• To investigate the relationship between distinct disgust sensitivity domains and specific OCD symptom clusters.
• To determine if disgust sensitivity predicts OCD symptoms independently of depression and anxiety.

Main Methods:

• A large sample of 1,005 undergraduate students completed online questionnaires.
• Measures included validated scales for OCD symptoms, depression, anxiety, and disgust sensitivity.
• Statistical analyses examined associations between OCD symptom groups and disgust sensitivity domains, controlling for covariates.

Main Results:

• Several OCD symptom groups, including checking, ordering, and washing, were significantly associated with disgust sensitivity, even after accounting for depression and anxiety.
• The strongest association emerged between washing symptoms and sensitivity to hygiene-related disgust stimuli.
• Further analysis suggested potential overlap between disgust and other aversive responses in disgust sensitivity measures.

Conclusions:

• Disgust sensitivity, particularly towards hygiene-related stimuli, is associated with washing symptoms in obsessive-compulsive disorder.
• The findings highlight the need to differentiate disgust from other aversions in OCD research and clinical assessment.
• Future research should aim to clarify the distinct roles of fear and disgust in the manifestation of OCD symptoms.
