Patterns of emotional and behavioural disturbance associated with autistic traits in young people with severe intellectual disabilities and challenging behaviours

Stereotyped behaviors predicting self-injurious behavior in individuals with intellectual disabilities

“…The data set did not provide this information as to the specific type of comorbid psychiatric diagnosis precluding statistical analysis. A review of the literature does appear to indicate the presence of mental health disorders as co-occurring with intellectual and developmental disorders at a higher rate than the general population (e.g., for intellectual disability and autism spectrum disorders, Bradley, Summers, Wood, & Bryson, 2004;Hill & Furniss, 2006). Thus, a comorbid mental health disorder may account for some proportion of the SIB not being predicted by stereotyped behavior among individuals with intellectual and developmental disabilities (see Matson & Turygin, 2012).…”

Temperament and its Relationship to Autistic Symptoms in a High-Risk Infant Sib Cohort

“…Paralleling findings with children, Bradley and Isaacs (2006) found higher levels of hyperactivity and impulsivity in cognitively-impaired adolescents with ASD, compared to controls with cognitive impairment alone. With regard to negative affect/neuroticism, adults and adolescents with ASD score higher on the harm avoidance scale of the TCI (Anckarsater et al 2006), the depression scale of the MMPI-2 , and the mood and anxiety scales of the DASH-II (Bradley et al 2004;Hill and Furniss 2006). Finally, adults and adolescents with ASD have self-reported lower levels of self-directiveness on the TCI (Anckarsater et al 2006;Soderstrom et al 2002), and more DSM symptoms of inattention (Bradley and Isaacs 2006), suggesting lower effortful control/constraint, and consistent with direct evidence of executive dysfunction on laboratory tasks (Hill 2004).…”

“…Relative to typical controls and individuals with other developmental disorders, adults with ASD have been found consistently to show differences on self-report scales that are conceptually related to Extraversion. For example, adults with ASD score lower on the novelty seeking and reward dependence scales of the Temperament and Character Inventory (TCI; Anckarsater et al 2006;Soderstrom et al 2002), score higher on the social introversion scale of the MMPI-2 , and show more social withdrawal on the Diagnostic Assessment for the Severely Handicapped-II (DASH-II; Hill and Furniss 2006). Paralleling findings with children, Bradley and Isaacs (2006) found higher levels of hyperactivity and impulsivity in cognitively-impaired adolescents with ASD, compared to controls with cognitive impairment alone.…”

Psychometric Analysis of the Social Communication Questionnaire Using an Item-Response Theory Framework: Implications for the Use of the Lifetime and Current Forms

“…Individuals with autism spectrum disorder (ASD) demonstrate many challenging behavioral patterns that can interrupt day-to-day functioning and classroom instruction (Dawson, Matson, and Cherry 1998;Hill and Furniss 2006;Matson and Shoemaker 2009). The difficulties that these individuals face communicating their thoughts (Aldred, Green, and Adams 2004), interpreting the expressions and communication of others (Howlin, Mawhood, and Rutter 2000), and understanding what is happening in their environment in lieu of sensory impairments or sensitivities (Rogers, Hepburn, and Wehner 2003;Tomchek and Dunn 2007) can have a negative effect on learning new skills and adaptive functioning in their environment.…”
