Speyer, Lydia Gabriela; Brown, Ruth Harriet; Ribeaud, Denis; Eisner, Manuel; Murray, Aja Louise – Journal of Autism and Developmental Disorders, 2023
A maladaptive response to stress in individuals with high ADHD traits may be a key factor explaining co-occurring ADHD symptoms and internalising problems. The current study investigates whether between-person differences in ADHD traits are associated with differences in the within-person moment-to-moment coupling of stress and negative affect;…

Cohen, Ira L.; Flory, Michael J. – Journal of Autism and Developmental Disorders, 2019
A recent cross-sectional analysis of PDD Behavior Inventory (PDDBI) data, analyzed with a classification and regression tree algorithm, yielded a decision tree (the Autism Spectrum Disorder-Decision Tree or ASD-DT) that detected three behaviorally distinct ASD subgroups: minimally verbal, verbal, and atypical. These subgroups differed in PDDBI…

There is growing evidence of a camouflaging effect among females with autism spectrum disorder (ASD), particularly among those without intellectual disability, which may affect performance on gold-standard diagnostic measures. This study utilized an age- and IQ-matched sample of school-aged youth (n = 228) diagnosed with ASD to assess sex…

Smith, Leann E.; Hong, Jinkuk; Greenberg, Jan S.; Mailick, Marsha R. – Journal of Autism and Developmental Disorders, 2016
The present study examined trajectories of adaptive behavior, behavior problems, psychological symptoms, and autism symptoms in adolescents and adults with fragile X syndrome (n = 147) over a three-year period. Adaptive behavior significantly increased over time, particularly for adolescents, and the severity of behavior problems decreased over…

Moulton, Emily; Barton, Marianne; Robins, Diana L.; Abrams, Danielle N.; Fein, Deborah – Journal of Autism and Developmental Disorders, 2016
Although for many children, Autism Spectrum Disorder (ASD) is a lifelong disability, a subset of children with ASD lose their diagnosis and show typical cognitive and adaptive abilities. The ages at which this transition can occur is not known, but it sometimes occurs quite early. Participants in the current study were 207 children with an ASD at…
