Background: Existing research has predominately focused on dyadic relationships in families of children with intellectual disabilities. The aim of this study was to build on emerging literature exploring triadic relationships between a mother, sibling, and child with intellectual disability, investigating how they influence each other's…

Background: Based on self-reported social capital, different typologies of family networks of people with intellectual disabilities were examined. Associations between behavioural and emotional problems or well-being and typologies were investigated. Method: 137 participants with mild intellectual disability were interviewed using the Family…

Background: The Family Network Method -- Intellectual Disability (FNM-ID) was used to compare perspectives of people with mild intellectual disability and their support workers on family networks of people with intellectual disability. Method: 138 participants with mild intellectual disability and support workers were interviewed, using the…

Emotional and behavioural problems occur more commonly in children with Autism Spectrum Disorder (ASD) compared to other children. Few studies have focused on these problems in children with ASD attending mainstream schools. We assessed via parent report the emotional and behavioural problems in 160 children aged 4-17 years with ASD attending…

Background: Longitudinal research is needed to strengthen evidence for risk factors for challenging behaviour in children with intellectual disabilities and to understand patterns of change over time. Methods: Data on challenging behaviour were collected for 225 students in one school over four annual time points and a range of potential risk…

Background: The Who's Challenging Who? (WCW) training is coproduced and delivered by people with intellectual disabilities (IDs), and it aims to improve staff empathy for people with challenging behaviour (CB). This study qualitatively describes trainees' and trainers' experiences of the WCW. Methods: Semi-structured interviews were undertaken…

We tested a novel methodological approach to examine associations between characteristics of autistic children and outcomes for siblings. Cluster analysis was used to define five groups of children with autism (n = 168) based on autism symptoms, adaptive behavior, pro-social behavior, and behavior problems. Primary and secondary parent carers, and…

Objectives: Behavioral and emotional problems exhibited by children with intellectual and developmental disabilities (IDD) have been identified as significant stressors for family members in both cross-sectional and longitudinal research. However, there is variability in the extent to which family members are affected by behavioral and emotional…

Background: Previous evaluations of community PBS teams have not investigated whether behaviour change is both statistically reliable and clinically significant. Few previous studies have reported quality of life (QoL) and social validity outcomes. Method: The present authors collected data on 85 people referred to a specialist PBS team. The…

Very little qualitative research has been carried out about the experiences of educators who deliver mathematics evidence-based teaching programmes to autistic students. Using a semi-structured format, we interviewed ten educators who had been delivering the Teaching Early Numeracy to Children with Developmental Disabilities (TEN-DD) programme for…

There is variability in the extent to which mothers are affected by the behavior problems of their children with developmental disabilities (DD). We explore whether maternal resilience functions as a protective or compensatory factor. In Studies 1 and 2, using moderated multiple regression models, we found evidence that maternal resilience…

School non-attendance in autism spectrum disorders has received very little attention to date. The study aimed to provide a comprehensive description of school non-attendance in students with autism spectrum disorders. Through an online survey, parents of 486 children (mean age: 11 years) reported on school attendance over 1 month and reasons for…

Previous research is not conclusive in detailing the prevalence of challenging behaviour and its correlates in children with intellectual disabilities in school settings in particular. In the current study, an amended version of the Behaviour Problems Inventory -- Short Form was used to collect data from a sample of 321 students in a special…

Background: Behaviour support plans (BSPs) are at the core of positive behavioural support for challenging behaviour, but nonadherence to BSPs is common. Generally, nonfluent component knowledge prevents learners achieving fluent application and retention of information, and we hypothesised that this may apply to staff learning BSPs. Method: We…

Parents of children with intellectual disabilities and/or autism have been shown to experience higher levels of distress than other parents. Despite such data having been available for several decades, the evidence base for psychological interventions to support parental well-being is small. Recent data suggest that both mindfulness and acceptance…
