Deontological Guilt Mediates the Effects of Personality on the Symptoms of Romantic Relationship Obsessive Compulsive Disorder (ROCD).

Objective: Relationship obsessive-compulsive disorder (ROCD), a clinical variant of OCD, is associated with personality traits and guilt sensitivity. Previous studies have not investigated whether the guilt associated with ROCD stems from deontological or altruistic morality. The main aim of the present study was to explore the differentiated impact of deontological and altruistic guilt on ROCD symptoms in romantic relationships. The study also aimed to test the mediating role of guilt in the relationships between personality traits and ROCD symptoms.

Method: Through linear regressions and path analysis, we examined the results of an online survey administered to 659 emerging adults, assessing the Big-5 personality traits, ROCD symptoms, and the moral orientation of guilt feelings (deontological/altruistic).

Results: Results revealed the negative influence of agreeableness and emotionality on ROCD symptoms. Moral dirtiness, as a facet of deontological moral orientation, was found to mediate the effects of personality predictors on relationship-centred but not on partner-focused ROCD symptoms, providing support for differential diagnosis.

Conclusions: These findings provide a clearer understanding of the cognitive determinants that sustain ROCD symptoms and offer evidence on associated personality traits. These results may represent a valuable source of knowledge for researchers as well as clinical therapists dealing with ROCD symptoms, couple disorders, and sexual dysfunction.
