The Affective Core of Delusional Disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Affective Science

Background:

• Investigating the interplay between personality traits, affectivity, and delusion severity in delusional disorder (DD).
• Assessing personality disorders, narcissistic traits, and emotional states in 32 DD outpatients.
• Utilizing Structured Interview for DSM-IV-TR Personality Disorders (SIDP-IV), Pathological Narcissism Inventory (PNI), Positive and Negative Affect Schedule (PANAS), and Psychotic Symptom Rating Scale (PSYRATS).

Discussion:

• Examining the prevalence of personality disorders within the DD patient sample.
• Analyzing correlations between delusion severity and various affective variables.
• Developing a multivariate model to explain delusion severity.

Key Insights:

• Delusion severity in DD is directly linked to narcissistic traits, specifically 'grandiose fantasy'.
• Feelings of shame, fear, and guilt are inversely associated with delusion severity.
• Shame emerged as the sole independent variable predicting delusion severity in the multivariate model.

Outlook:

• Suggests an affective core of shame underlying delusion severity in delusional disorder.
• Highlights the potential therapeutic target of addressing shame in DD treatment.
• Emphasizes the need for further research into the affective underpinnings of psychotic disorders.
