“…The lack of awareness of personality disorders in people treated by unskilled caregivers, not prepared to meet the challenges resulting from a personality disorder, may lead to negative consequences. Evidence-based treatments such as dialectical behavioural therapy and mentalisation-based therapy show little evidence of utility for people with ID diagnosed with a personality disorder [20] [21].…”

Personality disorder characteristics can be a complicating factor among people with intellectual disabilities (ID). Persons exhibiting such features are associated with risk for violence and service instability. The purpose of this paper was to study an evaluative tool for personality disorders in people with ID and mental health disorders in community-based services. A new staff-rated instrument, the Personality Disorder Characteristics Checklist (PDCC; Taylor & Novaco, 2013) [1], was used. This tool is designed to screen for ICD-10 dissocial and emotionally unstable personality traits. In the study, the instrument was assessed for both its reliability and validity. Fifty-two randomly selected patients with ID in the specialist habilitation services in Norway were scored on the PDSS. The male/female proportion was 30/22 and the mean age was 36.8 (SD = 13.4). The internal consistency of the PDCC was found to be very good. Supportive evidence for concurrent and discriminant validity was obtained in conjunction with other relevant staff-rated instruments. There were twenty-three patients who screened above cut-off for the diagnostic criteria of a personality disorder and two patients previously diagnosed with personality disorder. This demonstrates that such disorders are present in people with ID. It also suggests that such characteristics may have been neglected in the past in providing services to this population.

Purpose – The range of prevalence of personality disorder (PD) found in people with intellectual disability (ID) has been reported as vast, and has included data from dissimilar settings. The purpose of this paper is to review the reported prevalence of PD in the general population of people with ID, and to consider how different and changing ideas about PD have affected these rates. Design/methodology/approach – Cross-sectional studies of the prevalence of PD in people with ID were identified. The quality of the studies was considered, along with how cases of PD were identified. Findings – Six studies were included. The reported prevalence of PD in people known to have ID ranged from 0.7 to 35 per cent. Possible reasons for this wide range included different views of PD and methods of assessment. Research limitations/implications – The wide range of findings suggests that methodological differences are significant. Consideration to how clinicians should respond to the overlap of impairment between ID and PD may improve the conceptual clarity of PD, informing future epidemiological research. Originality/value – This review was limited to studies of samples likely to be representative of the general ID population. The range of prevalence estimates was narrower than previously reported, and more likely to reflect the true prevalence rate of PD amongst people who have ID. Consideration was also given to how different ideas of PD led to different methods and may have contributed to variance in the results.
