Recent research has suggested that people with autism spectrum disorder may be disproportionately at risk of substance use disorders. This study analyzed national-level Medicaid Claims data to compare substance use disorder prevalence among Medicaid enrollees with autism spectrum disorder (N = 388,426) and a random sample of enrollees without…

Purpose: An official autism diagnosis is required to access timely intervention and is associated with better long-term wellbeing and mental health. Certain demographic characteristics, such as being female or a racially or ethnically minoritized youth, have been associated with significant diagnostic lag. However, it remains unclear how assigned…

Objective: To estimate the percentage of U.S. working-age (18- to 64-year-old) adults in 2023 who self-reported ever being diagnosed with ADHD by a health care professional. Method: We analyze data from the 2023 National Wellbeing Survey (N = 7,053) to estimate self-reported lifetime ADHD diagnosis status among working-age adults, overall and by…

Purpose: The purpose of this journal-ready dissertation was to determine the extent to which differences existed in the attainment of Texas Education Agency approved industry-based certifications of Texas high school graduates by their ethnicity/race, gender, and economic status. In the first study, the degree to which the attainment of Texas…

Despite high rates of mental health concerns among youth, they are unlikely to receive mental health care, with mental health stigma acting as a barrier. The present study explores youth perceptions of the influences of stigma and what should be done to address it, drawing on a large (n = 705) mixed methods dataset of youth aged 14 to 24 from the…

Research increasingly seeks to answer the question: does special education work? This is different than asking if specific interventions have positive effects and instead aims to identify system-wide impacts. We systematically review published quantitative research on the impact of receiving special education services on student outcomes using…

Objective, Participants, & Methods: The COVID-19 pandemic has exacerbated mental health challenges of university students, staff, and faculty alike. We used linear mixed models to examine demographic predictors of, and change over time in, self-reported depression and anxiety symptoms of a cohort of university students and staff/faculty…

Objective: To examine inequalities in sleep quality during the COVID-19 pandemic by gender, sexual orientation, race/ethnicity, and socioeconomic position (SEP), and test associations between discrimination and sleep quality in a national longitudinal cohort of emerging adult college students. Participants: Participants were enrolled in college…

Students in the foster care system tend to have lower educational outcomes than their peers, including more frequent disciplinary events. However, few studies have explored how transitions into and out of foster care placements are associated with educational outcomes. Using longitudinal data from four California school districts, this study…

Objective: This study explored the structure validity and sex and country measurement invariance for Filipino and U.S. adults using the Five Factor Wellness Inventory (FFWEL-A2). Method: Confirmatory factor analysis and measurement invariance were conducted to determine consistency of responses across sex and country categories. Factorial ANOVAs…

Symptoms of ADHD occur during childhood, and many children continue to have symptoms and…

The capacity of the workforce lags behind the current demand for timely autism diagnostic assessment. Primary care providers (PCPs) are well-positioned to diagnose autism at earlier ages than providers from other disciplines. Thus, bolstering PCPs' diagnostic capabilities has been the focus of many recent capacity-building initiatives. Using data…

Using the 2017-2018 National Health and Nutrition Examination Survey (weighted population size = 35,460,209; 8-18 years old; 52.1% males), we compared the obesity prevalence in children and adolescents between body mass index-based (BMI-based) and total percent body fat-based (BF%-based, measured by the dual-energy x-ray absorptiometry) cutoffs.…

Recent empirical research shows that air pollution harms student test scores and attendance and increases office discipline referrals. However, the mechanism by which air pollution operates within schools to negatively affect student and teacher outcomes remains largely opaque. The existing literature has primarily focused on the effects of…
