A retrospective data analysis using 2000-2008 three state Medicaid Analytic eXtract was conducted to examine the prevalence and association of comorbidities (psychiatric and non-psychiatric) with healthcare utilization and expenditures of fee-for-service enrolled adults (22-64 years) with and without autism spectrum disorders (International…

Butwicka, Agnieszka; Långström, Niklas; Larsson, Henrik; Lundström, Sebastian; Serlachius, Eva; Almqvist, Catarina; Frisén, Louise; Lichtenstein, Paul – Journal of Autism and Developmental Disorders, 2017
Despite limited and ambiguous empirical data, substance use-related problems have been assumed to be rare among patients with autism spectrum disorders (ASD). Using Swedish population-based registers we identified 26,986 individuals diagnosed with ASD during 1973-2009, and their 96,557 non-ASD relatives. ASD, without diagnosed comorbidity of…

Planning Skills in Autism Spectrum Disorder across the Lifespan: A Meta-Analysis and Meta-Regression
Olde Dubbelink, Linda M. E.; Geurts, Hilde M. – Journal of Autism and Developmental Disorders, 2017
Individuals with an autism spectrum disorder (ASD) are thought to encounter planning difficulties, but experimental research regarding the mastery of planning in ASD is inconsistent. By means of a meta-analysis of 50 planning studies with a combined sample size of 1755 individuals with and 1642 without ASD, we aim to determine whether planning…

Tonnsen, Bridgette L.; Boan, Andrea D.; Bradley, Catherine C.; Charlest, Jane; Cohen, Amy; Carpenter, Laura A. – American Journal on Intellectual and Developmental Disabilities, 2016
Autism spectrum disorders (ASD) often co-occur with intellectual disability (ID) and are associated with poorer psychosocial and family-related outcomes than ID alone. The present study examined the prevalence, stability, and characteristics of ASD estimates in 2,208 children with ASD and ID identified through the South Carolina Autism and…

M. – Autism: The International Journal of Research and Practice, 2016
It is unknown whether sex influences the diagnostic evaluation of autism spectrum disorder, or whether male and female adults within the spectrum have different symptom profiles. This study reports sex differences in clinical outcomes for 1,244 adults (935 males and 309 females) referred for autism spectrum disorder assessment. Significantly, more…

Alexeeff, Stacey E.; Yau, Vincent; Qian, Yinge; Davignon, Meghan; Lynch, Frances; Crawford, Phillip; Davis, Robert; Croen, Lisa A. – Journal of Autism and Developmental Disorders, 2017
This study examines medical conditions diagnosed prior to the diagnosis of autism spectrum disorder (ASD). Using a matched case control design with 3911 ASD cases and 38,609 controls, we found that 38 out of 79 medical conditions were associated with increased ASD risk. Developmental delay, mental health, and neurology conditions had the strongest…

Saqr, Youssra; Braun, Erika; Porter, Kyle; Barnette, Debra; Hanks, Christopher – Autism: The International Journal of Research and Practice, 2018
Little has been reported about how to improve health care access and delivery for adolescents and adults with autism spectrum disorder. To understand the contributions to the health disparities in the autism spectrum disorder population, we conducted two independent research approaches to learn about current medical needs. A retrospective chart…

Gardner, Lauren M.; Campbell, Jonathan M.; Bush, Andrew J.; Murphy, Laura – Journal of Psychoeducational Assessment, 2018
We contrasted Behavior Assessment System for Children, Second Edition--Parent Rating Scales--Preschool Form (BASC-2 PRS-P) parent ratings for 242 (52% African American; 39% White) preschool-aged children from three diagnostic groups: autism spectrum disorder (ASD), intellectual disability (ID), and ASD and ID (ASD/ID). Across diagnostic groups,…

Bowers, Katherine; Wink, Logan K.; Pottenger, Amy; McDougle, Christopher J.; Erickson, Craig – Autism: The International Journal of Research and Practice, 2015
The objective of the study was to characterize the phenotype of males and females with autism spectrum disorder born preterm versus those born at term. Descriptive statistical analyses identified differences between male and female autism spectrum disorder subjects born preterm compared to term for several phenotypic characteristics and…

High-functioning children with autism spectrum disorders often find writing challenging. These writing difficulties may be specific to autism spectrum disorder or to a more general clinical effect of attention disturbance, as these children are often comorbid for attention-deficit/hyperactivity disorder (ADHD) symptomatology (and children with…

Van Den Heuvel, Ellen; Botting, Nicola; Boudewijns, Inge; Manders, Eric; Swillen, Ann; Zink, Inge – First Language, 2017
This study investigated three conversational subskills in children with 22q11.2 deletion syndrome (22q11.2DS, n = 8, ages 7-13) and Williams syndrome (WS, n = 8, ages 6-12). The researchers re-evaluated these subskills after 18 to 24 months and compared them to those of peers with idiopathic intellectual disability (IID) and IID and comorbid…

Groom, Madeleine J.; Kochhar, Puja; Hamilton, Antonia; Liddle, Elizabeth B.; Simeou, Marina; Hollis, Chris – Journal of Autism and Developmental Disorders, 2017
This study investigated the neurobiological basis of comorbidity between autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). We compared children with ASD, ADHD or ADHD+ASD and typically developing controls (CTRL) on behavioural and electrophysiological correlates of gaze cue and face processing. We measured effects…

The prevalence, severity and symptom profiles for major depressive disorder (MDD) were compared in samples of boys and adolescents with and without an autism spectrum disorder (ASD). Self-reports were obtained on the Depression subscale of the Child and Adolescent Symptoms Inventory (CASI-D) with 70 ASD and 50 non-ASD male participants between the…

Rosa, Mireia; Puig, Olga; Lázaro, Luisa; Calvo, Rosa – Autism: The International Journal of Research and Practice, 2016
Previous studies have shown high rates of comorbid disorders in children and adolescents with autism spectrum disorder, but failed to compare them with general population and few of them have identified predictors of comorbidity. This study compared the rates of psychiatric disorders in 50 children and adolescents with autism spectrum disorder, 24…
