Background: The Nisonger Child Behavior Rating Form (NCBRF) allows for the assessment of frequency and severity of challenging behaviours of individuals with ID with one combined rating. However, frequency and severity rating of challenging behaviours may be in disagreement. Therefore, the efficacy of frequency and severity independent ratings for…

Background: Epilepsy and challenging behaviour are both highly prevalent in the intellectual disability (ID) population and it is thus crucial to understand any possible associations between the two. Method: PsycINFO, MEDLINE, Embase, CINAHL and Web of Science were searched for quantitative data about epilepsy and any forms of challenging…

Background: Although there has been interest in the influence of cognitions on the relationship between challenging behaviour and maternal wellbeing, there is an absence of measures to specifically examine parents' perceptions of challenging behaviour. The psychometric properties of the Challenging Behaviour Perception Questionnaire (CBPQ;…

Positive behaviour support (PBS) has become well established as an intervention approach for individuals with intellectual disability and challenging behaviour. However, what remains unexplored is the relationship between PBS and the medical and social models of disability, which historically are the dominant conceptual frameworks put forward in…

Background: There is limited research documenting the health and/or psychological services accessed by adults with rare genetic syndromes who engage in challenging behaviour. The study documented service receipt and associations with person characteristics. Method: Thirty-two parents of adults with rare genetic syndromes completed an adapted…

Background: Mothers of children with autism experience high levels of stress. However, little is known about whether maternal stressors differ across children of different ages. Method: This study investigated stressors in mothers of 29 pre-school-aged and 27 school-aged children with autism. Correlation and regression analyses were used to…

Background: Understanding adaptive behaviour variability in children with autism spectrum disorder (ASD) may have important implications for early intervention. The purpose of this study was to explore whether autism symptom severity and caregiver depression affected adaptive behaviour in young children with ASD. Method: Data were collected from…

Background: Challenging behaviours are frequently shown by children with an intellectual disability. This study documents service use within this population and explores its relationship with challenging behaviours and child and parent characteristics.Method Forty-nine mothers of young children with an intellectual disability or global…

Background: There is a need for a more accurate characterisation of higher level restricted and repetitive behaviour (RRB) in autism spectrum disorder (ASD), including why it might be considered problematic and events associated with its occurrence. Method: We selected one form of higher level RRB--arranging and ordering--that was rated as severe…

Background: Positive behaviour support (PBS) emphasises multi-component interventions by natural intervention agents to help people overcome challenging behaviours. This paper investigates which components are most effective and which factors might mediate effectiveness. Method: Sixty-one staff working with individuals with intellectual disability…

Background: Individuals with intellectual disability (ID) and legal involvement are a unique population with complex needs. To date, there has been limited research exploring the demographic and clinical profiles of individuals with ID and legal involvement that are in crisis and how they differ to individuals with ID without legal involvement.…

Background: Parenting stress was investigated in mothers with a child with Angelman syndrome (AS) or Prader-Willi syndrome (PWS), which are genetically related. Method: Mothers of 24 children with AS and 23 children with PWS (2-12 years) completed the Nijmegen Parenting Stress Index-Short, Developmental Behaviour Checklist, and Vineland Screener…

Background: Past research has determined that fear of violence is often "irrational" in relation to the actual level of risk presented. This has been found to exacerbate the negative effects of exposure to work-related violence. Aims: This study investigates fear of assault in relation to exposure to challenging behaviour. The extent to which a…
