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

Abstract

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

Risk of Suicide and Dysfunctional Patterns of Personality among Bereaved Substance Users

“…The presence of PD is a greatly prevalent comorbid disorder among substance users [22,23,24,25]. In fact, different studies have demonstrated a high level of comorbidity between PD and SUD [26,27,28,29,30,31]. As Krueger and Eaton [32] stated, comorbidity is the rule not the exception.…”

A View of Personality Disorder from the Colonial Periphery

“…Epidemiological studies and national population surveys done in the USA, Canada, New Zealand and Europe have indicated prevalence rates of personality disorder between 13−15% (39−41). The Jamaican population prevalence rate compares with a rate of 28% for the diagnosis of personality disorder in non-psychiatric patients of medical wards of the UHWI (35) and 57% in patients in the psychiatric wards of that hospital (36). The differences between the international rates and the Jamaican rate may be explained by at least one of two factors.…”

“…The JPDI was successfully validated on a cohort of 200 patients at the University Hospital of the West Indies (UHWI), using the validating comparisons of the semistructured interviews of the DSM-IV-TR personality disorder classification and the International Personality Disorder Inventory (IPDE) as the gold standard inventory (34). Using this methodology, the prevalence rates of personality disorder in medical wards, psychiatric ward patients and substance abuse ward patients at UHWI were also established (35,36). A four-stage stratified random sampling method was used to obtain a representative population sample consisting of 1506 Jamaicans to establish the prevalence of personality disorder in the Jamaican population using the JPDI as the diagnostic screening instrument, conducted by Market Research Services Limited (38), a reputable Jamaican market research organization.…”

The Prevalence of Personality Disorder in a General Medical Hospital Population in Jamaica

“…Currently, there are no prevalence rates of personality disorder in Jamaica. This series of studies attempts to identify the prevalence of personality disorder in a cohort of psychiatric in-patients (6) and the population prevalence of personality disorder (7). The present study attempts to determine the prevalence rate of personality disorder in an inpatient medical population without a concomitant psychiatric disorder.…”
