Sexual hallucinations and delusions in borderline personality disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Trauma Studies

Background:

• Sexual hallucinations are well-documented in schizophrenia spectrum disorders but understudied in borderline personality disorder (BPD).
• Prevalence rates and phenomenological characteristics of sexual hallucinations and delusions in BPD remain largely unknown.
• Understanding these phenomena is crucial for comprehensive BPD assessment and treatment.

Purpose of the Study:

• To determine the prevalence of sexual hallucinations and delusions in individuals with BPD.
• To explore the phenomenological characteristics of these experiences.
• To investigate the association between childhood trauma and sexual hallucinations/delusions in BPD.

Main Methods:

• A cross-sectional study was conducted with 81 outpatients diagnosed with BPD.
• Participants completed the Sexual Hallucinations and Delusions Questionnaire (SHDQ), PSYRATS-AVH, and Childhood Trauma Questionnaire (CTQ).

Main Results:

• Lifetime prevalence rates were 59.3% for sexual hallucinations and 49.4% for sexual delusions.
• Somatic, visual, tactile, and auditory hallucinations were more common than olfactory/gustatory.
• All participants reported childhood trauma, with emotional and sexual abuse strongly linked to sexual hallucinations and delusions.

Conclusions:

• Sexual hallucinations and delusions are highly prevalent in BPD and may contribute to characteristic emotional and behavioral symptoms.
• The universal reporting of childhood trauma underscores its significant impact and warrants further investigation in this population.
• Clinical practice should consider these findings, including potential treatment implications for trauma survivors with BPD.
