Disgust-Related Personality Traits in Men with Olfactory Dysfunction

Area of Science:

• Psychology
• Neuroscience
• Olfactory Research

Background:

• Disgust is a fundamental emotion with individual differences in proneness, sensitivity, and self-disgust.
• Olfaction plays a critical role in triggering disgust responses.
• Persistent olfactory dysfunction, such as anosmia and hyposmia, may impact disgust-related personality traits.

Purpose of the Study:

• To investigate disgust dispositions in individuals with olfactory dysfunction.
• To compare disgust proneness, disgust sensitivity, and self-disgust between patients with anosmia, hyposmia, and normosmic controls.

Main Methods:

• A comparative study involving male patients with anosmia (n=16), hyposmia (n=20), and normosmic men (n=20).
• Assessment of disgust proneness (DP), disgust sensitivity (DS), and self-disgust (SD) using validated questionnaires.
• Statistical comparison of DP, DS, and SD scores across the three groups.

Main Results:

• Dysosmic patients (anosmia and hyposmia) exhibited lowered disgust proneness towards spoilage.
• Elevated disgust proneness towards poor hygiene and increased self-disgust were reported by dysosmic patients.
• No significant group differences were found in disgust sensitivity.

Conclusions:

• Olfactory dysfunction is associated with domain-specific alterations in disgust dispositions, particularly concerning hygiene and self-perception.
• Elevated personal disgust in olfactory dysfunction may stem from challenges related to body odor perception and hygiene maintenance.
• These changes might contribute to social insecurity in individuals with olfactory impairments, warranting further investigation with neuroimaging techniques.
