Fragile X syndrome (FXS) is the leading known inherited cause of intellectual disability and the most common known biological cause of autism. Approximately 25% to 50% of males with FXS meet full diagnostic criteria for autism. Despite the high comorbidity between FXS and autism and the ability to diagnose FXS prenatally or at birth, no studies have examined indicators of autism in infants with FXS. The current study focused on indices of visual attention, one of the earliest and most robust behavioral indicators of autism in idiopathic (non-FXS) autism. Analyses revealed lower HR variability, shallower HR decelerations, and prolonged look durations in 12-month old infants with FXS that were correlated with severity of autistic behavior but not mental age.

Positive behavioral interventions and supports (PBIS) and school mental health (SMH) are prominent initiatives in the United States to improve student behavior and promote mental health and wellness, led by education and mental health systems, respectively. Unfortunately, PBIS and SMH often operate separately in districts and schools, resulting in a number of missed opportunities for interconnecting programs and services and increasing their depth and quality within multitiered frameworks of prevention, support, and intervention. The current article details a necessary first step in the process of improved interconnection of these two frameworks by describing the development of a process and tool for schools/ districts to assess readiness for connecting PBIS and SMH through a blended system. Relevant literature, pilot data, and methodology are discussed, in addition to psychometric properties of the survey and future applications of this instrument for practice, research, and policy.
