The Prevalence of Personality Disorder in a Psychiatric and Substance Abuse Population in Jamaica



Objective: To determine the prevalence of personality disorders in patients admitted to the psychiatric wards of the University Hospital of the West Indies (UHWI).

Method: Patients (n = 100) sequentially admitted to the psychiatric wards of the UHWI were assessed for personality disorder using the gold standard of a consultant assessment using the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision (DSM IV-TR) diagnostic criteria for personality disorder, the International Personality Disorder Examination Screening questionnaire (IPDE-S), and the Jamaica Personality Disorder Inventory (JPDI).

Results: The three assessment instruments identified a prevalence of personality disorder in the cohort of patients of 51% consultant DSM-IV-TR assessment, 57% JPDI and 86% IPDE-S. The prevalence rate identified by the IPDE-S was significantly higher that the local instruments used (p < 0.000).

Conclusions: The prevalence of personality disorder assessed by the JPDI and the consultant DSM IVTR instruments in Jamaica is comparable to the prevalence rate of studies in other countries in a similar population.
