Hahn, Laura J.; Fidler, Deborah J.; Hepburn, Susan L. – American Journal on Intellectual and Developmental Disabilities, 2014
The present study compares the adaptive behavior profile of 18 young children with Williams syndrome (WS) and a developmentally matched group of 19 children with developmental disabilities and examines the relationship between adaptive behavior and problem behaviors in WS. Parents completed the Vineland Adaptive Behavioral Scales--Interview…

Daunhauer, Lisa A.; Fidler, Deborah J.; Hahn, Laura; Will, Elizabeth; Lee, Nancy Raitano; Hepburn, Susan – American Journal on Intellectual and Developmental Disabilities, 2014
We investigated executive functioning (EF) in children with Down syndrome (DS; n = 25) and typically developing (TD) children matched for mental age (MA; n = 23) using the Behavior Rating Inventory of Executive Function-Preschool. We sought to (1) compare children with DS to a developmentally matched control group, and (2) to characterize the EF…

Bottema-Beutel, Kristen; Lloyd, Blair; Carter, Erik W.; Asmus, Jennifer M. – American Journal on Intellectual and Developmental Disabilities, 2014
Attaining reliable estimates of observational measures can be challenging in school and classroom settings, as behavior can be influenced by multiple contextual factors. Generalizability (G) studies can enable researchers to estimate the reliability of observational data, and decision (D) studies can inform how many observation sessions are…

Sterling, Audra M.; Warren, Steven F.; Brady, Nancy; Fleming, Kandace – American Journal on Intellectual and Developmental Disabilities, 2013
This study investigated the influence of maternal and child variables on the maternal responsivity of 55 mothers with young children with fragile X syndrome. Data included video observations of mother-child interactions in four different contexts, standardized assessments with the children, and standardized questionnaires for the mothers. The…

Esbensen, Anna J.; Mailick, Marsha R.; Silverman, Wayne – American Journal on Intellectual and Developmental Disabilities, 2013
Parental characteristics were significant predictors of health, functional abilities, and behavior problems in adults with Down syndrome ("n" ?=? 75) over a 22-year time span, controlling for initial levels and earlier changes in these outcomes. Lower levels of behavior problems were predicted by improvements in maternal depressive…

Ingersoll, Brooke; Walton, Katherine; Carlsen, Danielle; Hamlin, Theresa – American Journal on Intellectual and Developmental Disabilities, 2013
Individuals with autism have difficulty with social skills across the lifespan. Few social interventions have been examined for older individuals with autism who also have significant intellectual disabilities (ID). Previous research suggests that reciprocal imitation training (RIT) improves imitation and social engagement in young children with…

Son, Esther; Parish, Susan L.; Swaine, Jamie G.; Luken, Karen – American Journal on Intellectual and Developmental Disabilities, 2013
This study examines the accuracy of self-report of cervical and breast cancer screening by women with intellectual disability ("n" ?=? 155). Data from face-to-face interviews and medical records were analyzed. Total agreement, sensitivity, specificity, positive predictive value and negative predictive value were calculated. Total…

Moss, Joanna; Howlin, Patricia; Hastings, Richard Patrick; Beaumont, Sarah; Griffith, Gemma M.; Petty, Jane; Tunnicliffe, Penny; Yates, Rachel; Villa, Darrelle; Oliver, Chris – American Journal on Intellectual and Developmental Disabilities, 2013
We evaluated autism spectrum disorder (ASD) characteristics and social behavior in Angelman (AS; "n" ?=? 19; mean age ?=?10.35 years), Cornelia de Lange (CdLS; "n" ?=? 15; mean age ?=?12.40 years), and Cri du Chat (CdCS, also known as 5 p-syndrome; "n" ?=? 19; mean age ?=? 8.80 years) syndromes. The proportion of…

Lense, Miriam D.; Dykens, Elisabeth M. – American Journal on Intellectual and Developmental Disabilities, 2013
Williams syndrome (WS) is a neurodevelopmental disorder associated with hypersociability and anxiety. However, little is known about how these salient aspects of the phenotype are related or their underlying physiology. We examined cortisol reactivity in WS because cortisol is responsive to psychosocial stress. Compared to typically developing…

Tonnsen, Bridgette L.; Shinkareva, Svetlana V.; Deal, Sara C.; Hatton, Deborah D.; Roberts, Jane E. – American Journal on Intellectual and Developmental Disabilities, 2013
Anxiety is among the most impairing conditions associated with Fragile X syndrome (FXS) and is putatively linked to atypical physiological arousal. However, few studies have examined this association in young children with FXS. The authors examined whether patterns of arousal and behavior during an experimental stranger approach paradigm differ…

Wilkinson, Krista M.; McIlvane, William J. – American Journal on Intellectual and Developmental Disabilities, 2013
Augmentative and alternative communication (AAC) systems often supplement oral communication for individuals with intellectual and communication disabilities. Research with preschoolers without disabilities has demonstrated that two visual--perceptual factors influence speed and/or accuracy of finding a target: the internal color and spatial…

Smith, Ashlyn L.; Romski, MaryAnn; Sevcik, Rose A. – American Journal on Intellectual and Developmental Disabilities, 2013
This study examined communication interaction patterns when one sibling had a developmental disability as well as the role of communication skills in sibling relationship quality. Thirty sibling dyads were categorized into one of three communication status groups: emerging, context-dependent, and independent communicators. Independent…

Hoch, John; Symons, Frank; Sng, Sylvia – American Journal on Intellectual and Developmental Disabilities, 2013
There have been limited direct tests of the hypothesis that self-injurious behavior (SIB) regulates arousal. In this study, two autonomic biomarkers for physiological arousal (heart rate [HR] and the high-frequency [HF] component of heart rate variability [HRV]) were investigated in relation to SIB for 3 participants with intellectual…

Klusek, Jessica; Martin, Gary E.; Losh, Molly – American Journal on Intellectual and Developmental Disabilities, 2013
This study tested the hypothesis that pragmatic (i.e., social) language impairment is linked to arousal dysregulation in autism spectrum disorder (ASD) and fragile X syndrome (FXS). Forty boys with ASD, 39 with FXS, and 27 with typical development (TD), aged 4-15 years, participated. Boys with FXS were hyperaroused compared to boys with TD but did…

Moskowitz, Lauren J.; Mulder, Emile; Walsh, Caitlin E.; McLaughlin, Darlene Magito; Zarcone, Jennifer R.; Proudfit, Greg Hajcak; Carr, Edward G. – American Journal on Intellectual and Developmental Disabilities, 2013
Despite the increased risk for anxiety disorders in children with autism spectrum disorders (ASD), there is a lack of research on the assessment and treatment of anxiety in this population, particularly for those with an intellectual disability (ID). The present study evaluated a multimethod strategy for the assessment of anxiety and problem…
