The prevalence of personality disorder assessed by the Jamaica Personality Disorder Inventory (JPDI) and the consultant Diagnostic and Statistical Manual of Mental Disorders fourth edition-text revision (DSM IV-TR) instruments in Jamaica is comparable to the prevalence rate of studies in other countries in a similar population.

The correlates of psychosexual phenomenology in the Jamaican population using the seven questions of the Jamaica Personality Disorder Inventory (JPDI) are presented. More than one-fifth of the sample reported some degree of heterosexual and homosexual dysfunction. Significant levels of multiple sexual partnerships and feelings of infidelity in a swathe of Jamaican people reveal underlying psychosexual anxiety and guilt, poor impulse control and difficulties with partner intimacy.

The creation and validation of the 38-question Jamaica Personality Disorder Inventory (JPDI) screening questionnaire for the diagnosis of personality disorder piloted on patients from psychiatric and medical wards at the University Hospital of the West Indies is described.
