Prospects for Leveling the Playing Field for Black Children With Autism.

Among the many race-based health disparities that have persistently plagued the US population,1 the disproportionate burden of adverse neurodevelopmental outcomes to Black children affected by autism spectrum disorder (ASD) is particularly devastating given its major lifelong consequences. Recently, in 3 successive reports from the Autism and Developmental Disabilities Monitoring (ADDM) program of the US Centers for Disease Control and Prevention (CDC) (birth cohort years 2014, 2016, and 2018), we and our collaborators reported that although the prevalence of community-diagnosed ASD had equalized for Black and non-Hispanic White (NHW) children in the United States, there has persisted a pronounced racial disparity in the proportion of ASD-affected children with comorbid intellectual disability (ID), on the order of 50% for Black children with ASD vs 20% for White children with ASD.2 Here, we provide data to support the following: much earlier diagnosis is possible; early diagnosis alone is not likely to close the ID comorbidity disparity; and judicious efforts over care as usual are necessary to ensure that Black children have access to timely implementation of developmental therapy, for which we observed promising associations with improved cognitive and adaptive outcomes in our sample.

Improving Beverage Choice in Adults with Developmental Disabilities: Implementation of a Token Reinforcement System in a Community Residential Setting.

Individuals with developmental disabilities (DD) are twice as likely to have obesity than non-disabled individuals. Replacing the consumption of sugar sweetened beverages (SSBs) with water has many health benefits, including weight reduction. In this study, a token reinforcement system was implemented to increase water consumption and decrease the consumption of SSBs with 14 adult participants with DD living in a community-based independent supported living (ISL) center. Token reinforcement reduced the consumption of SSBs, with associated reductions in calorie consumption and body weight. Findings are especially important for treatment settings where resources for individualized meal planning and staffing to support comprehensive behavioral interventions may be limited.

On the Importance of Listening and Intercultural Communication for Actions against Racism.

In a period where racial inequities in the United States have garnered more attention and discussion as a result of social media (e.g., increased use of the #BlackLivesMatter hashtag; Anderson et al., 2020) and newer generations (Tatum, 2017b), it is important to ensure that communication between cultural groups is effective and produces systemic change. This article will review the failures of a "postracial" society, with emphasis on ineffective communication among Black, Indigenous People of Color and non-Black, Indigenous People of Color. The role of the listener during intercultural verbal exchanges will be examined, while highlighting the barriers and harmful results of ineffective communication. A behavioral conceptualization of effective listener behavior will be presented, which if implemented, may maintain and sustain social equity, inclusion, and justice. A call to action will be made to further investigate intercultural communication using behavior-analytic research methodologies and how such research might inform on how to functionally and precisely mediate reinforcement in the fight against racism.

Increasing Exercise Intensity: Teaching High-Intensity Interval Training to Individuals with Developmental Disabilities Using a Lottery Reinforcement System.

Rates of overweight and obesity are above 70% in typically developing adults in the United States, with higher rates observed in individuals diagnosed with developmental disability (DD). Lottery reinforcement systems have been validated as effective exercise interventions for individuals with DD. Although high-intensity interval training (HIIT) has demonstrated health benefits, it has not been studied using individuals within this population. The purpose of this study was to implement a lottery reinforcement system to systematically increase heart rate (HR) during 30-min HIIT sessions with 3 adults with DD. Results demonstrated increases in HR from below to within the prescribed range in all 3 participants. For 1 participant, weight decreased by 10.8 pounds during the 9-week program. Implications include that lottery systems increase exercise intensity with adults with DD, that HR during exercise can be reliably controlled using a lottery system, and that similar programs may result in health benefits.

PEAK Pre-Assessments: Preliminary Evidence Establishing Internal Consistency and Construct Validity.

Promoting the Emergence of Advanced Knowledge (PEAK) is a behavior-analytic tool that assesses and teaches language and cognitive abilities. PEAK preassessment total scores showed statistically significant correlations with measures of intelligence (r = .703, p = .023) and adaptive behavior (r = .618, p = .018), whereas no significant correlations were found between PEAK and age, autism diagnostic instruments, or aggression scales in a sample (N = 18) receiving behavior-analytic assessment in an autism clinic. Statistically significant correlations were found between all modules within the PEAK system (p ≤ .001). Results provide preliminary evidence of the construct validity and internal consistency of the PEAK preassessments.
