Background: The diagnosis of depression in severe and profound intellectual disability is challenging. Without adequate skills in verbal self-expression, standardized diagnostic criteria cannot be used with confidence. The purpose of this systematic review was to investigate the assessment and diagnosis of unipolar depression in severe and…

Background: Obsessive-compulsive (O-C) traits, and excessive food intake are well known behavioural manifestations among individuals with Prader-Willi Syndrome (PWS). Other unwanted behaviours are also frequently observed, but they need a more specific investigation, especially in the adult population. Methods: The behaviour of 31 PWS adults was…

Background: Little is known about client characteristics that are related to outcome during inpatient treatment of adults with mild intellectual disability (ID) and severe behavioural problems. Method: We explored variables that were related to a change in behavioural problems in 87 individuals with mild ID during inpatient treatment in facilities…

Background: Many people with intellectual disabilities display high levels of anger, and cognitive-behavioural anger management interventions are used routinely. However, for these methods to be used optimally, a better understanding is needed of different forms of anger assessment. The aim of this study was to investigate the relationship of a…

Background: The triad of impairments characteristic of autistic spectrum disorders and severe challenging behaviours are reasonably common among adults with intellectual disabilities. The aim was to investigate whether they had an impact on lifestyle among such adults living in staff-supported community housing. Methods: Data were collected on the…

Background: Achenbach & Rescorla (2003) recently developed the Adult Behavior Checklist (ABCL) to assess psychopathology in the general population. The ABCL should be completed by a proxy informant. The use of proxy informants, instead of self-reporting, makes the ABCL potentially suitable for the assessment of psychopathology in adults with…

Background: Effectively supporting individuals with intellectual disabilities who display challenging behaviours continues to be a priority for service providers. Person-focused training (PFT) is a model of service delivery which provides staff with skills in functional assessment and intervention development. Existing longitudinal data from a…

Background: There is a general agreement in the literature that no systematic correlation exists between parental intellectual disability "per se" and parenting performance. Yet, a few studies in the field of parents and parenting with intellectual disability have explored other potential determinants of parenting and child outcomes. In…

Background: We examined the benefits of risperidone, including quality of life (QoL), in the treatment of violent and self-injurious behaviour in adults with moderate, severe or profound intellectual disability. Methods: Twenty-four participants received open-label, oral, flexible-dose risperidone of 0.5-6 mg/day for 12 weeks. Efficacy was…

Background: This study aimed to evaluate the effectiveness of the Parents Plus programme with families of pre-school children with developmental disabilities and significant behavioural problems in the Irish health service.
