Autism spectrum disorder (ASD) affects individuals across all racial and ethnic groups, yet rates of diagnosis are disproportionately higher for Black and Hispanic children. Caregivers of children with ASD experience significant stressors, which have been associated with parental strain, inadequate utilization of mental health services and lower quality of life. The family peer advocate (FPA) model has been utilized across service delivery systems to provide family-to-family support, facilitate engagement, and increase access to care. This study used a randomized controlled design to examine the efficacy of FPAs in a racially and ethnically diverse sample. Results demonstrate significantly increased knowledge of ASD and reduced levels of stress for caregivers who received the FPA intervention as compared to treatment as usual.

Integrated behavioral health services have positive outcomes for patients and providers, but little is known about providers' perspectives on implementing these services. This community-based participatory research collaboration with a Federally Qualified Health Center examined provider perspectives on implementing a collaborative psychiatry consultation program in pediatric primary care. We interviewed providers (N = 14) from psychiatry, social work, primary care, and psychology regarding their experiences implementing the program, and their recommendations for its sustainability. Providers described interdisciplinary integration arising from the program, with accompanying benefits (e.g., increased access to care for patients with complex diagnostic profiles, increased learning and role satisfaction among providers), and challenges (e.g., increased burden on primary care providers, potential patient discomfort with team-based care). Our results highlight the complexities of implementing collaborative psychiatry consultation in pediatric primary care, and suggest the importance of supporting primary care providers and patients within this context.

Phelan–McDermid syndrome (PMS) is one of the most common genetic forms of autism spectrum disorder (ASD). While sensory reactivity symptoms are widely reported in idiopathic ASD (iASD), few studies have examined sensory symptoms in PMS. The current study delineates the sensory reactivity phenotype and examines genotype–phenotype interactions in a large sample of children with PMS. Sensory reactivity was measured in a group of 52 children with PMS, 132 children with iASD, and 54 typically developing (TD) children using the Sensory Assessment for Neurodevelopmental Disorders (SAND). The SAND is a clinician-administered observation and corresponding caregiver interview that captures sensory symptoms based on the DSM-5 criteria for ASD. Children with PMS demonstrated significantly greater hyporeactivity symptoms and fewer hyperreactivity and seeking symptoms compared to children with iASD and TD controls. There were no differences between those with Class I deletions or sequence variants and those with larger Class II deletions, suggesting that haploinsufficiency of SHANK3 is the main driver of the sensory phenotype seen in PMS. The syndrome-specific sensory phenotype identified in this study is distinct from other monogenic forms of ASD and offers insight into the potential role of SHANK3 deficiency in sensory reactivity. Understanding sensory reactivity abnormalities in PMS, in the context of known glutamatergic dysregulation, may inform future clinical trials in the syndrome.

ObjectiveThere is a critical need to identify biomarkers and objective outcome measures that can be used to understand underlying neural mechanisms in autism spectrum disorder (ASD). Visual evoked potentials (VEPs) offer a noninvasive technique to evaluate the functional integrity of neural mechanisms, specifically visual pathways, while probing for disease pathophysiology.MethodsTransient VEPs (tVEPs) were obtained from 96 unmedicated children, including 37 children with ASD, 36 typically developing (TD) children, and 23 unaffected siblings (SIBS). A conventional contrast-reversing checkerboard condition was compared to a novel short-duration condition, which was developed to enable objective data collection from severely affected populations who are often excluded from electroencephalographic (EEG) studies.ResultsChildren with ASD showed significantly smaller amplitudes compared to TD children at two of the earliest critical VEP components, P60-N75 and N75-P100. SIBS showed intermediate responses relative to ASD and TD groups. There were no group differences in response latency. Frequency band analyses indicated significantly weaker responses for the ASD group in bands encompassing gamma-wave activity. Ninety-two percent of children with ASD were able to complete the short-duration condition compared to 68% for the standard condition.ConclusionsThe current study establishes the utility of a short-duration tVEP test for use in children at varying levels of functioning and describes neural abnormalities in children with idiopathic ASD. Implications for excitatory/inhibitory balance as well as the potential application of VEP for use in clinical trials are discussed.

Despite strong initial interest, college students—especially those from underrepresented minority (URM) backgrounds—leave STEM majors at high rates. Here, we explore the role of racial phenotypic stereotypicality, or how typical one’s physical appearance is of one’s racial group, in STEM persistence. In a longitudinal study, URM students were especially likely to leave STEM to the extent that they looked more stereotypical of their group; Asian American students were especially likely to leave STEM to the extent that they looked less stereotypical. Three experiments documented a possible mechanism; participants (Studies 2–4), including college advisors (Study 3), attributed greater STEM ability to more-stereotypical Asian Americans and to less-stereotypical Black women (not men), than to same-race peers. Study 4 showed that prejudice concerns, activated in interactions with Black men (not women), account for this gender difference; more-stereotypical Black men (like women) were negatively evaluated when prejudice concerns were not salient. This work has important implications for ongoing efforts to achieve diversity in STEM.
