This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

The Nisonger Child Behavior Rating Form (NCBRF) was developed to specifically screen psychopathology and problem behavior in children and adolescents with IDD. This study aimed to update the NCBRF to the "Diagnostic and Statistical Manual of Mental Disorders, 5th Edition" (DSM-5) and screen for the most prevalent psychopathologies that…

This 10-year study followed 134 caregivers of young adults with autism and intellectual disability, examining the effects of caregivers' coping strategies, sociodemographic features, and young adult symptomatology on caregiver well-being and depression. Lower caregiver education and higher young adult externalizing behaviors predicted lower…

Interventions that promote parent and child well-being in families with children with intellectual and developmental disabilities (IDD) are important, given the caregiving burden often associated with supporting children with developmental and behavioral challenges. This article summarizes a presentation made at the 2019 AAIDD annual conference…

Two non-U.S. quasi-experimental studies reported Active Support training was associated with increased engagement in individuals with IDD, but no randomized controlled trials (RCTs) exist. We evaluated effects of Active Support training on staff assistance, and social and nonsocial engagement in 75 individuals with intellectual and developmental…

Children with fragile X syndrome (FXS) display wide-ranging intellectual and behavioral abilities that affect daily life. We describe the educational setting of students with FXS and assess the relationships between school setting, co-occurring conditions, and functional ability using a national survey sample (n = 982). The majority of students…

It is well documented that mothers of children with challenging behavior (CB) experience elevated levels of stress and that this persists over time, but less is known about the experience of mothers of children with rare genetic syndromes. This article describes 2 studies, 1 cross-sectional and 1 longitudinal, comparing well-being in mothers of…

This secondary analysis examined the impact of respondent-level factors on scores on the "Supports Intensity Scale--Children's Version" (SIS-C) for children and youth with intellectual disability to determine if there were any significant differences in the SIS-C scores by different respondent pairs when considering children's age,…

The Diagnostic Adaptive Behavior Scale (DABS) was developed using item response theory (IRT) methods and was constructed to provide the most precise and valid adaptive behavior information at or near the cutoff point of making a decision regarding a diagnosis of intellectual disability. The DABS initial item pool consisted of 260 items. Using IRT…

This study identified trajectories of depressive symptoms among mothers of children with or without intellectual disability longitudinally across eight time points. Results of fitting a linear growth model to the data from child ages 3-9 indicated that child behavior problems, negative financial impact, and low dispositional optimism all…

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…

Children with intellectual and developmental disabilities (IDD) experience significant difficulties in attention, learning, executive functions, and behavioral regulation. Emerging evidence suggests that computerized cognitive training may remediate these impairments. In a double blind controlled trial, 76 children with IDD (4-11 years) were…
