Objective: The goal of the present study is to describe the ADHD phenotype from childhood to adolescence in Black and White girls in a community sample. Method: Primary caregivers enrolled in the population-based, longitudinal Pittsburgh Girls Study reported on girls' ADHD symptoms and impairment from ages 7 to 17; diagnostic subtypes were…

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders of childhood. It is characterized by a pattern of inattention, impulsivity, or hyperactivity that leads to functional impairment experienced in multiple settings. Symptoms of ADHD occur during childhood, and many children continue to have symptoms and…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

This study examined whether domain-general cognitive weaknesses in processing speed (PS) or executive functioning (EF) moderate the relation between word reading scores and anxiety such that lower word reading scores in combination with lower cognitive scores are associated with higher anxiety symptoms. The sample consisted of 755 youth ages 8-16…

Caregivers of children with attention deficit-hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) experience more stress than caregivers of typically developing children but there is limited research evaluating caregivers' quality of life (QoL). This study aimed to describe the association of caregiver QoL in children with ASD and/or…

Autism spectrum disorder and attention deficit/hyperactivity disorder are neurodevelopmental disorders with high rates of co-occurrence. However, there is a dearth of large, nationally representative studies examining the prevalence of co-occurring autism spectrum disorder and attention deficit/hyperactivity disorder among children. The aim of…

Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

Background: Adverse childhood experiences (ACEs) have long been associated with attention-deficit/hyperactive disorder (ADHD) diagnoses in children; but the data used is now over 6 years old (from 2017 to 2018). Understanding the current landscape of their prevalence and association is needed to capture evolving social, environmental, and economic…

Background: Integrated primary care (IPC) can address prevalent behavioral health concerns identified in pediatric office visits, but research on IPC consultation patterns is limited. Objective: This study investigated variation in consultation rates across presenting problems, patient sociodemographic factors, and IPC treatment duration. Method:…

Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10 subtest primary battery was evaluated across sex, age (6-8, 9-11, 12-14, and 15-16 year-olds), and three diagnostic (attention-deficit/hyperactivity disorder, anxiety, and encephalopathy) groups within a large clinical sample (N = 5359) referred to a…

Academic acceleration, which enhances challenges for academically gifted students, can be subject-based or whole-grade. Limited research has explored its application in the twice-exceptional population, where students possess notable cognitive strengths and challenges due to psychological diagnoses. Our clinical study investigates the likelihood…

Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities are the most commonly diagnosed neurodevelopmental disorders in children and often coexist. Previous research has suggested that the prevalence of these conditions may differ by race and Hispanic origin. Using timely, nationally representative data, this report examines the…

Children with autism spectrum disorder have a high risk of vision problems yet little is known about their vision care. This cross-sectional survey study, therefore, examined vision care among 351 children with autism spectrum disorder ages 6-17 years in the United States or Canada who were enrolled in the Autism Treatment Network Registry. Vision…

Background: We examined racial/ethnic disparities in school-based behavioral health service use for children with psychiatric disorders. Methods: Medicaid claims data were used to compare the behavioral healthcare service use of 23,601 children aged 5-17 years by psychiatric disorder (autism, attention deficit hyperactivity disorder [ADHD],…

Research on the effects of physical activity on children with attention deficit hyperactivity disorder is promising, yet no attempt has been made to integrate current findings using meta-analytic techniques. Using a meta-regression, the present study examined the effectives of physical activity for children with attention deficit hyperactivity…
