Background: Behavioural problems in individuals with intellectual disabilities have a negative impact on them. Limited assessment measures exist in Spain. This study aimed to validate the Behavior Problems Inventory--Short Form (BPI-S) in the Spanish population by examining its psychometric properties and factorial structures. Method: This study…

Background: Children with severe developmental disabilities are frequently excluded from research, and little is known about their quality of life (QoL). Using a mixed-methods approach, this study examined relationships between school factors and QoL for these children and their families. Method: 171 parents of children with severe developmental…

Background: This study explored understandings that service-users with intellectual disabilities and challenging behaviour held around their behaviour, what shaped these understandings, and the relationship between how behaviours are managed and well-being. Methods: Eight participants (three female, five male) partook in individual semi-structured…

Background: This study aimed to examine the associations between individual staff and staff team characteristics and quality of life of individuals with intellectual disabilities and challenging behaviours. Method: With multilevel analyses, we examined educational level, experience, attitudes and behaviours of 240 staff members, in relation to…

Background: Perception of exertion is essential for self-regulation in sports. The ability to rate perceived exertion (RPE) is regarded as psychophysiological competence, although cognitive components of RPE are largely unknown. The present study tested the hypothesis that cognitive processing speed, perseveration and figural fluency correlate…

Background: As individuals with intellectual and developmental disabilities (IDD) grow older, siblings are likely to become caregivers for their brothers and sisters with IDD. Thus, it is important to identify the correlates of sibling caregiving to facilitate transitions to caregiving roles. Method: This study involved the secondary analysis of a…

Background: Behaviour problems are most common in people with intellectual disabilities. Nature of behaviour problems can vary depending upon the age, sex and intellectual level (IQ). Objectives: This study examined the distribution of behaviour problems across intellectual disability categories and their association with IQ age and sex in…

Background: Parents often play a lifelong role in supporting their sons and daughters with intellectual and/or developmental disabilities (IDD). There is a need to better understand parent resources, particularly when the individual with IDD has behaviour problems, as the latter has consistently been linked to parental burden. Methods: The current…

Background: In the UK, people with intellectual disabilities who exhibit aggressive behaviour often receive community-based specialist health services from a community learning disability team (CLDT). Our aim was to estimate costs associated with this provision and to identify predictors of higher costs. Method: Costs were estimated for 60 adults…

Background: The Manchester Attachment Scale-Third party observational measure (MAST) was developed to assess secure attachment style for adults with intellectual disabilities. The psychometric properties of the MAST were examined. Materials and Methods: Professional carers (N = 40) completed the MAST and measures related to the construct of…

Background: Psychometric properties of three functional assessment rating scales were compared for three types of target behaviours [self-injurious behaviour (SIB), stereotypic behaviour and aggressive/destructive behaviour]. Materials and method: The "Questions about Behavioural Function" (QABF), the "Functional Assessment for…

Background: Previous research has suggested that severity of intellectual disability (ID) and topography of behaviour may influence staff causal attributions regarding challenging behaviour. Subsequently, these causal attributions may influence helping behaviours. This study investigated the relationship between attributions of control over…

Background: Childhood sexual and physical abuse has been related to subsequent offending behaviour in non-disabled individuals as well as people with intellectual disabilities, but there is a dearth of research examining the link between these two characteristics and psychological, behavioural and psychiatric symptoms amongst sex offenders with…

Background: Reliable measures of aggressive challenging behaviour are required if interventions aimed at reducing this behaviour among people with intellectual disability (ID) are to be formally evaluated. The present authors examined the reliability of the Modified Overt Aggression Scale (MOAS), an instrument not yet formally tested in those with…

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…
