Although natural supports benefit individuals with intellectual and developmental disabilities (IDD), little is known about natural support provided within specific life domains or how race/ethnicity or support from professionals impacts the extent of natural support one receives. In this study, 518 parents of adults with IDD responded to a national survey about natural supports, including who provides support, the number of supporters, and variables that predict natural supports. Family most often provided support, although professionals and family friends were frequent supporters in several domains. Natural support was most extensive in health, least extensive in employment and housing. Individuals with IDD who regularly participated in daytime activities and/or identified as Black had more extensive natural support. Implications are discussed.

Hyperphagia is highly penetrant in Prader-Willi syndrome (PWS) and has increasingly been reported in other neurogenetic conditions (NGC). The Hyperphagia Questionnaire (HQ) was completed by caregivers of 4-8-year-olds with PWS (n = 17), Angelman syndrome (AS; n = 22), Williams syndrome (WS; n = 25), or low-risk controls (LRC; n = 35). All NGC groups were significantly elevated in HQ Total and Behavior scores compared to LRC. Only AS and WS were significantly elevated in the Drive domain, and only PWS in the Severity domain. After controlling for externalizing behavior, HQ Total scores were higher for PWS relative to other groups. Hyperphagic symptoms may not differentiate PWS from other NGCs in early childhood. However, hyperphagic phenotypes may be most severe in PWS. Further investigation of these profiles may inform etiology and syndrome-specific treatments.

Measurement invariance (MI) is a psychometric property of an instrument indicating the degree to which scores from an instrument are comparable across groups. In recent years, there has been a marked uptick in publications using MI in intellectual and developmental disability (IDD) samples. Our goal here is to provide an overview of why MI is important to IDD researchers and to describe some challenges to evaluating it, with an eye towards nudging our subfield into a more thoughtful and measured interpretation of studies using MI.

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 behaviors and higher levels of internalizing and externalizing behaviors across almost all domains compared to typically developing controls. There was some evidence that these differences were greatest in older children, and more apparent in those with co-occuring epilepsy. This characterization of the phenotype of SYNGAP1-ID significantly aids our understanding of the behavioral profile of this population and is a step towards the development of tailored interventions.

Individuals with intellectual and developmental disabilities (IDD) continue to experience disparities in health and well-being despite improved provisions of person-centered care. Patient-centered outcomes research (PCOR) translates evidence into practice for meaningful outcomes. This piece describes findings from an environmental scan and stakeholder outreach to identify and prioritize opportunities to enhance IDD PCOR data infrastructure. These opportunities include developing a standardized research definition; advancing data standards for service systems; improving capture of IDD at point of care; developing standardized outcome measures; and encouraging Medicaid data use for IDD research. Within this piece, we discuss the implications of addressing data gaps for enhanced research. While the identified activities provide a path towards advancing IDD PCOR data infrastructure, collaborative efforts between government, researchers, and others are paramount.

The present study aims to understand and describe family caregivers' perceptions and experiences regarding contact and relationships with their adult relatives with intellectual and developmental disabilities (IDD) living in supported accommodation during the COVID-19 lockdown. A qualitative phenomenological approach was applied in which 19 Israeli family caregivers (parents and siblings) were interviewed. Inductive thematic analysis revealed themes at the microsystem level (the resident, the caregiver, and their relationship), and at the mesosystem level (the caregivers' interactions with service providers and other residents' families). The findings highlight the pivotal role of family caregivers in times of uncertainty and the need to develop explicit policies and mechanisms to facilitate family engagement in the residents' lives.

Loss of function variants in the Cyclin-dependent kinase-like 5 gene (CDKL5) causes CDKL5 deficiency disorder (CDD). Most cases of CDD are due to a de novo missense or truncating variants. The CDKL5 gene was discovered in 1998 as part of the genomic mapping of the chromosome Xp22 region that led to the discovery of the serine-threonine kinases STK9. Since then, there have been significant advancements in the description of the disease in humans, the understanding of the pathophysiology, and the management of the disease. There have been many lessons learned since the initial description of the condition in humans in 2003. In this article, we will focus on pathophysiology, clinical manifestations, with particular focus on seizures because of its relevance to the medical practitioners and researchers and guidelines for management. We finalize the manuscript with the voice of the parents and caregivers, as discussed with the 2019 meeting with the Food and Drug Administration.

Diagnostic overshadowing is a bias in which symptoms of a psychological disorder are falsely attributed to a known diagnosis of intellectual disability. This systematic review evaluated all research on diagnostic overshadowing conducted to date, including dissertations and peer-reviewed journal articles. In total, 25 studies were included in this review. Findings suggest diagnostic overshadowing may not be as ubiquitous as originally believed, with one third of included studies finding no overshadowing. The quality of the evidence was graded as "Low" using the LEGEND tool, with common issues including outdated studies, analogue methodologies, small sample sizes and convenience samples, and inappropriate conducting or reporting of statistical analyses. Implications for the field and recommendations for future research are discussed.
