People with Down syndrome (DS) commonly experience challenges with sleep, executive functioning, everyday memory, and symptoms of attention deficit hyperactivity disorder (ADHD). A path analysis was conducted to determine if executive function mediated the relationship between sleep problems and both everyday memory and ADHD symptoms. Parents of 96 children and youth with DS completed questionnaires related to sleep, executive functioning, everyday memory, and ADHD symptoms. Results showed that executive functioning fully mediated the relation between sleep and both everyday memory and ADHD symptoms. Implications for education and intervention for children and youth with DS are discussed.

Between 1% and 2% of the U.S. population has an intellectual disability (ID) and often experience disparities in health care. Communication patterns and sedation use for routine medical procedures are important aspects of care for this population. We explored physicians' communication patterns and sedation use in caring for patients with significant levels of ID through a mailed survey of 1,400 physicians among seven specialties in outpatient settings (response rate = 61.0%). Among physicians who saw at least one patient with significant levels of ID in an average month, 74.8% reported usually/always communicating primarily with someone other than the patient. Among specialists, 85.5% (95% CI: 80.5%-90.5%) reported doing so, compared to 69.9% (95% CI: 64.4%-75.4%) for primary care physicians (p < 0.001). Also, 11.4% reported sedating at least one patient with significant levels of ID for a routine procedure. Three quarters of physicians reported communicating primarily with persons other than the patient usually or always-an approach that, in some instances, may not align with best medical practice. The percentage of physicians who report sedating at least one individual is associated with significant ID and the physician's volume of patients with significant ID.

In this study, we focus on Rubinstein-Taybi syndrome (RTS) to explore the associations between executive function deficits and repetitive behaviors. Thirty individuals with RTS completed direct assessments of inhibition, working memory and set-shifting. Informants completed repetitive behavior and executive function questionnaires. Repetitive questions were associated with poorer inhibition and working memory. Stereotypy was associated with poorer inhibition. Adherence to routines was associated with poorer set-shifting, but only on the parental report measure. No other associations were evident. There is evidence of an association between specific repetitive behaviors and executive functioning in RTS, suggesting executive dysfunction may underpin behavioral difference in RTS. The findings point towards specific associations that are of interest for further research across populations in which repetitive behaviors are present.

Due to the unique social cognitive profiles of individuals with autism spectrum disorder (ASD) with and without intellectual disability (ID) sharing coherent and complex personal narratives can be challenging. To address these challenges research has focused on teaching macrostructure components using visual supports and repeated opportunities to practice. Despite success by young children with ASD and ID, the application of this instruction for adults with ASD with and without ID is still largely unknown. An ABAB single case withdrawal design was used to determine the effects of a personal narrative intervention to teach macrostructure within participant-generated personal narratives. Results indicate all participants demonstrated more coherent and complex personal narratives with the intervention. The results and implications for practice are discussed.

Variation in the FMR1 gene may affect aspects of cognition, such as executive function and memory. Environmental factors, such as stress, may also negatively impact cognitive functioning. Participants included 1,053 mothers of children with and without developmental disabilities. Participants completed self-report measures of executive function, memory, and stress (i.e., life events, parenting status), and provided DNA to determine CGG repeat length (ranging from 7 to 192 CGGs). Stress exposure significantly predicted greater self-reported difficulties in executive function and the likelihood of memory problems. Cubic CGG effects independently predicted executive function and memory difficulties, suggesting effects of both genetic variation and environmental stress exposure on cognitive functioning.

We examined potential phenotypic differences in eye gaze avoidance exhibited by boys with autism spectrum disorder (ASD) and boys with fragile X syndrome (FXS). In Study 1, the Eye Contact Avoidance Scale (ECAS) was administered to caregivers of boys aged 7-18 years with FXS (n = 148), ASD (n = 168), and mixed developmental disabilities (MDD; n = 128). In Study 2, subsets of boys with FXS (n = 31) and boys with ASD (n = 25) received a brief behavioral treatment probe to improve eye contact. Results showed that boys with FXS obtained significantly higher scores on the ECAS compared to boys with ASD and MDD. Exposure to the brief behavioral treatment probe resulted in significant decreases in scores for boys with FXS, but not for boys with ASD.

This study aimed to examine the level of discrimination against people with intellectual disability during COVID-19, and assessed stereotypes, levels of familiarity with people with intellectual disability, and personal experiences with COVID-19 as potential correlates. A cross-sectional study was conducted using a large sample from the Dutch population (n = 1,797). Salient stereotype factors of people with intellectual disability were "friendly" and "in need of help," but not "give nuisance." Those respondents who were unfamiliar with people with intellectual disability in real life demonstrated higher levels of discrimination, perceiving them as more of a nuisance and as being less in need of help, in comparison to those who were more familiar. People with intellectual disability were judged by an ambivalent set of stereotypes during the COVID-19 pandemic that were in line with pre-COVID-19 findings and as such seemed to be fairly persistent and robust. There is a pressing need to both raise awareness of stereotypes towards and discrimination against people with intellectual disability via advocacy and education, and to facilitate positive encounters.

This study compared mental state language (talk about emotions, thoughts, intentions, etc.) used by 6- to 11-year-old children with Down syndrome (DS) to a younger typically developing (TD) comparison group matched by nonverbal cognition. We aimed to determine (1) whether mental state language use is delayed in DS relative to developmental expectations, and (2) if there are differences between groups in the association between mental state language and developmental factors (emotion knowledge, expressive language). Rate of mental state language use was significantly lower in the group with DS, but the number of different mental state terms was not significantly different. Nuanced patterns of similarity and difference emerged between groups regarding the association between mental state language and other developmental factors.

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 affect children and adolescents with IDD. The authors re-aligned the existing items to fit within a DSM-5 framework, and then used the Delphi method with a panel of experts in IDD to evaluate the NCBRF items. The revision process included deleting and revising existing items and formulating new items. We obtained a final item pool after three iterations. The Delphi process and resulting item pool are described in this article.
