Prevalence of aggressive challenging behaviours in intellectual disability and its relationship to personality status: Jamaican study

Abstract

Despite previous difficulties in assessing personality disorder in intellectual difficulties the ICD-11 classification was easy to administer in practice in this population, and the higher problem behaviour scores in those with greater severity of personality disturbance support its construct validity.

The Problem Behaviour Checklist: short scale to assess challenging behaviours

“…In the first, a field study was carried out for the World Health Organization on personality status and aggressive challenging behaviour in patients with intellectual disability in Jamaica. 11 The participant population was selected from a specialist intellectual disability high school (School of Hope), a supported care home and an adult day centre for people with intellectual disabilities, all operated by the Jamaican Association on Intellectual Disabilities (JAID) in Kingston, Jamaica.…”

Nidotherapy compared with enhanced care programme approach training for adults with aggressive challenging behaviour and intellectual disability (NIDABID): cluster‐randomised controlled trial

“…The research assistants visited the care homes at monthly intervals over a 15‐month period (with some initial ones being before trial allocation) and recorded episodes of challenging behaviour using the following instruments after meeting staff and checking records: The MOAS (Sorgi et al ) with at least one resident having a score of 4 at baseline to enter the study; The Problem Behaviour Check List (PBCL). A new scale developed initially in a previous study (Tyrer et al ), consisting of seven items of behaviour covering all aggressive behaviour, self‐harm, inappropriate sexual behaviour, demanding and oppositional behaviour, and wandering (Tyrer et al ), The Quantification of Aggression Scale (Tyrer et al ) developed in the course of assessing patients in the Dangerous and Serious Personality Disorder Programme, and only intended for the assessment of serious violent episodes, using a score of 9 as the threshold for severe violence. …”

“…As aggressive challenging behaviour in people with ID is often associated with personality disorder (Tyrer et al ) and has a limited overlap with antisocial behaviour, nidotherapy was considered to be an appropriate intervention and, after being tested briefly in care homes, was considered to be desirable in this setting.…”

Nidotherapy: a cost‐effective systematic environmental intervention

“…Many disorders can be treated by nidotherapy, and it can be described as a transdiagnostic treatment. In general, it is reasonable to consider nidotherapy when a problem is either not amenable to known evidence‐based therapies (e.g., intellectual disability, most personality disorders) or has failed to respond to such treatments, for which the most evidence is in schizophrenia.…”
