Mothers of children with an intellectual disability often experience challenges that affect their mental health and the relationship with their children. The present study assesses the correlation between the mental health and relationship patterns of mothers of children with an intellectual disability. In this descriptive-correlational study, the…

We aimed to identify unique constellations of sensory phenotypes for genetic etiologies associated with diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Caregivers reported on sensory behaviors via the Sensory Profile for 290 participants (younger than 25 years of age) with ASD and/or ID diagnoses, of which…

Background: The present study aimed at investigating mother-child dyadic co-regulation patterns in dyads with children with intellectual disability (ID). Method: 24 children paired for developmental age and vocabulary size (8 with chromosome 14 aberrations, 8 with Down syndrome, and 8 with typical development) and their mothers participated in the…

Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

The purpose of the study was to analyze the historical patterns in the relationship between specific types of disabilities and frequency of drug abuse or weapon offenses in public schools in the United States using the U.S. Department of Education Open Data Platform's (n.d.) data sets from 2011-2012 through 2020-2021.

While assessment of a psychiatric disorder in ASD and ID generally is challenging, identification of post-traumatic stress disorder (PTSD) seems particularly so, and knowledge does…

Background: The risks and opportunities associated with the use of technologies are of growing research interest. Patterns of technology usage illuminate these opportunities and risks. However, no studies have assessed the usage patterns (frequency, duration, and intensity) and related factors in young people with intellectual disabilities.…

The predictive ability of early consonant inventory and intentional communication on later expressive language was examined in 36 boys with fragile X syndrome (FXS). Autism symptom severity was included as a potential moderator. Participants were visited in their homes twice over a 6-year period, and mother-child interactions were videotaped,…
