Saima, Sohei; Ihara, Hiroshi; Ogata, Hiroyuki; Gito, Masao; Murakami, Nobuyuki; Oto, Yuji; Ishii, Atsushi; Takahashi, Asami; Nagai, Toshiro – American Journal on Intellectual and Developmental Disabilities, 2022
The relationship between sensory processing and ASD-like and associated behaviors in patients with Prader-Willi Syndrome (PWS) remains relatively unexplored. Examining this relationship, 51 adults with PWS were administered the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), Short Sensory Profile (SSP-J), Food-Related…

Adlof, Suzanne M.; Klusek, Jessica; Hoffmann, Anne; Chitwood, Kerrie L.; Brazendale, Allison; Riley, Karen; Abbeduto, Leonard J.; Roberts, Jane E. – American Journal on Intellectual and Developmental Disabilities, 2018
Individuals with fragile X syndrome (FXS) present with significant deficits in reading skills, but scant research exists to understand the characteristics of the reading delays or best practices for reading instruction with this population. Study 1 examined the relationship between phonological awareness and reading skills in individuals with FXS.…

Chan, Wai; Smith, Leann E.; Greenberg, Jan S.; Hong, Jinkuk; Mailick, Marsha R. – American Journal on Intellectual and Developmental Disabilities, 2017
The present investigation explored long-term relationships of behavioral symptoms of adolescents and adults with developmental disabilities with the mental health of their mothers. Fragile X premutation carrier mothers of an adolescent or adult child with fragile X syndrome (n = 95), and mothers of a grown child with autism (n = 213) were…

Robinson, Ashley N.; Roberts, Jane E.; Brady, Nancy C.; McQuillin, Samuel D.; Warren, Steven F. – American Journal on Intellectual and Developmental Disabilities, 2016
The present study examined the relationship between salivary cortisol and maternal responsiveness in mothers of boys with fragile X syndrome (FXS). Maternal responsivity is strongly associated with child outcomes, and children with FXS are at risk for compromised development due to intellectual disability and problem behavior. Increased…

Pitts, C. Holley; Mervis, Carolyn B. – American Journal on Intellectual and Developmental Disabilities, 2016
We describe the performance of 292 4- to 17-year-olds with Williams syndrome (WS) on the Kaufman Brief Intelligence Test-2 (KBIT-2; Kaufman & Kaufman, 2004). Mean IQ Composite, Verbal standard score (SS), and Nonverbal SS were in the borderline range relative to the general population, with variability similar to the general population.…

Kover, Sara T.; McCary, Lindsay M.; Ingram, Alexandra M.; Hatton, Deborah D.; Roberts, Jane E. – American Journal on Intellectual and Developmental Disabilities, 2015
Fragile X syndrome (FXS) is associated with significant language and communication delays, as well as problems with attention. This study investigated early language abilities in infants and toddlers with FXS (n = 13) and considered visual attention as a predictor of those skills. We found that language abilities increased over the study period of…

Shashi, Vandana; Wray, Emily; Schoch, Kelly; Curtiss, Kathleen; Hooper, Stephen R. – American Journal on Intellectual and Developmental Disabilities, 2013
Children with 22q11.2 deletion syndrome exhibit high rates of social-behavioral problems, particularly in the internalizing domain, indicating an area in need of intervention. The current investigation was designed to obtain information regarding parent and teacher ratings of the social-emotional behavior of children with 22q11DS. Using the Child…

Greenberg, Jan S.; Seltzer, Marsha Mailick; Baker, Jason K.; Smith, Leann E.; Warren, Steven F.; Brady, Nancy; Hong, Jinkuk – American Journal on Intellectual and Developmental Disabilities, 2012
We examine how the family environment is associated with aspects of the Fragile X syndrome phenotype during childhood, adolescence, and adulthood. Mothers of children (n = 48), adolescents (n = 85), and adults (n = 34) with Fragile X syndrome participated in a multisite study. For children and adults with Fragile X syndrome, the presence of warmth…

Hatton, Deborah D.; Wheeler, Anne; Sideris, John; Sullivan, Kelly; Reichardt, Alison; Roberts, Jane; Clark, Renee; Bailey, Donald B., Jr. – American Journal on Intellectual and Developmental Disabilities, 2009
To describe the early phenotype of girls with full mutation fragile X, we used 54 observations of 15 girls between the ages of 6 months and 9 years to examine developmental trajectories as measured by the Battelle Development Inventory. In this sample, autistic behavior was associated with poorer developmental outcomes, primarily due to…

May, Michael E.; Srour, Ali; Hedges, Lora K.; Lightfoot, David A.; Phillips, John A., III; Blakely, Randy D.; Kennedy, Craig H. – American Journal on Intellectual and Developmental Disabilities, 2009
A functional polymorphism in the promoter of the gene encoding monoamine oxidase A has been associated with problem behavior in various populations. We examined the association of MAOA alleles in adult males with intellectual/developmental disabilities with and without established histories of problem behavior. These data were compared with a…
