Facon, Bruno; Magis, David; Courbois, Yannick – American Journal on Intellectual and Developmental Disabilities, 2021
The aim of this study was to examine the developmental trajectories of comprehension of relational concepts among 557 participants with intellectual disability (ID) of undifferentiated etiology (M age = 12.20 years, SD = 3.18) and 557 typically developing (TD) participants (M age = 4.57 years, SD = 0.80). Logistic regression analyses, with…

Cook, Alexandria; Quinn, Emily D.; Rowland, Charity – American Journal on Intellectual and Developmental Disabilities, 2021
Individuals with a comorbid diagnosis of Down syndrome (DS) and autism spectrum disorder (ASD) have been found to exhibit greater deficits in expressive communication than individuals with DS only. We hypothesized that individuals with a comorbid diagnosis (n = 430) would have significantly lower Communication Matrix scores and specifically social…

Elevated salivary cortisol levels have been documented in individuals who engage in self-injurious behavior (SIB), indicating acute physiological stress. Less is known about the chronicity of stress and SIB. We analyzed the relationship between parent ratings of problem behavior and hair cortisol concentrations (an index of chronic adrenocortical…

The Early Communication Indicator (ECI) was designed to measure expressive communication progress in young children. We evaluated using the 6-min ECI procedure for a new purpose--a sampling context for stable measures of vocal development of young children with autism spectrum disorder (ASD). We evaluated how many ECI sessions were required to…

Fielding-Gebhardt, Heather; Bredin-Oja, Shelley L.; Warren, Steven F. – American Journal on Intellectual and Developmental Disabilities, 2021
The development of an expressive language score for people with autism based on the ADOS-2 was recently reported by Mazurek et al. (2019). The current study examined the construct validity of the ADOS-2 expressive language score (ELS) in a sample of adolescents with fragile X syndrome (n = 45, 10 girls), a neurodevelopmental disorder with high…

Langley, Emma; Totsika, Vasiliki; Hastings, Richard P.; Bailey, Tom – American Journal on Intellectual and Developmental Disabilities, 2021
We explored whether reports of three dyadic relationships (marital/partner, parent-child, sibling) were related to perceptions of family functioning in 467 mothers of children with intellectual disability aged 4-15 years. Structural equation models were fitted to examine associations between relationship indicators and family functioning. The…

We estimated the effects of information avoidance and information seeking among parents of children diagnosed with autism spectrum disorder (ASD) on age of diagnosis. An online survey was completed by 1,815 parents of children with ASD. Children of parents who self-reported that they had preferred "not to know," reported diagnoses around…
