A brief screening instrument for emotionally unstable and dissocial personality disorder in male offenders with intellectual disabilities

The impact of transforming care on the care and safety of patients with intellectual disabilities and forensic needs

NHS England recently published a national plan to develop community services for people with intellectual disabilities and autism who display challenging behaviour by using resources from the closure of a large number of hospital beds. An ambitious timescale has been set to implement this plan. The bed closure programme is moving ahead rapidly, but there has been little progress in developing community services to support it. This paper discusses the impact of the gap between policy and practice on the care and safety of patients with intellectual disabilities and forensic needs who form a distinct subgroup of the target population and are being disproportionately affected by this government policy.

Examining the psychometrics of the Psychopathology Inventory for Mentally Retarded Adults-II for individuals with mild and moderate intellectual disabilities

With growing recognition of the occurrence of psychological disorders in individuals with intellectual disability (ID), researchers and clinicians alike have placed emphasis on developing measures to assess for psychopathologies in this population. Despite an increased interest in the topic, there is still a dearth of psychometrically robust measures available to assess for psychopathology in adults with mild and moderate ID. The purpose of this study was to examine the psychometric properties of a revised measure for psychopathology in individuals with mild and moderate ID, the Psychopathology Inventory for Mentally Retarded Adults - second edition (PIMRA-II). Internal consistency, inter-rater reliability, and test-retest reliability were investigated. Validity was studied via convergent validity by comparing the PIMRA-II to the Assessment of Dual Diagnosis (ADD) and via discriminate validity by comparing the PIMRA-II to the Social Performance Survey Schedule (SPSS) prosocial scores. Lastly, an exploratory factor analysis was conducted to determine the factor structure of the scale.

Measuring preparedness for mammography in women with intellectual disabilities: a validation study of the Mammography Preparedness Measure

BACKGROUND

Women with intellectual disabilities have similar breast cancer rates as the general population, but lower rates of regular mammography and higher breast cancer mortality rates. Although prior qualitative work demonstrates that women with intellectual disabilities face unique, disability-specific barriers to mammography, the present authors lack standardized, validated instruments for measuring knowledge of breast cancer screening in this population. In addition, much research related to adults with intellectual disabilities focuses on family or carer perspectives, rather than involving women with intellectual disabilities, themselves.

METHODS

The present authors first pilot tested a general population instrument measuring breast cancer knowledge, and found that it did not perform adequately in women with intellectual disabilities. In response, the present authors developed the Mammography Preparedness Measure (MPM), a direct short interview tool to measure knowledge and preparedness in women with intellectual disabilities, themselves, rather than relying on caregiver or other reports, and using inclusive methodology. The present authors validated the MPM by assessing test-retest reliability.

RESULTS

Average test-retest per cent agreement of 84%, ranging from 74 to 91% agreement per item, with an overall kappa of 0.59.

CONCLUSION

The MPM appears to be a valid instrument appropriate for measuring mammography preparedness in women with intellectual disabilities. The success of this innovative tool suggests that direct, rather than informant-directed tools can be developed to measure health knowledge and cancer screening readiness in adults with intellectual disabilities, an important measure in studying and reducing disparities.

Psychiatric disorders in people with intellectual disability (intellectual developmental disorder): forensic aspects

PURPOSE OF THE REVIEW

Persons with intellectual disability come into frequent and underreported contact with the legal system. Advances in forensic psychiatry help better identify persons with intellectual disability in forensic contexts, inform evaluation and treatment, and elucidate unique characteristics of this population. With the release of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), forensic psychiatrists must adjust to changes in the diagnostic process.

RECENT FINDINGS

This review examines the past year's contributions to the literature, including predictors among offenders with intellectual disability, concurrent diagnoses, efficacy of competence restoration, means of studying individuals with intellectual disability, and impact of DSM-5.

SUMMARY

Impoverished personal relationships are found to be an important predictor of offense among persons with intellectual disability. A Personality Disorder Characteristics Checklist allows screening for personality disorders (indicative of increased risk of violence) among intellectual disability offenders. Referrals to specialists for treatment more often occur for violent and sexual offenses than for other offenses. Competence restoration is historically low among those with intellectual disability, specially compared with those referred for substance abuse and personality disorders. However, the Slater Method results in higher rates of restoration than traditional training methods. DSM-5 alters the definition of intellectual disability, moving from an IQ-oriented diagnosis system to a multifaceted approach, introducing more flexibility and nuance.
