Objective: We leveraged common genetic variation underlying ADHD, educational attainment (EA) and cognition (COG) to understand the nature of the Behavior Rating Inventory for Executive Functions (BRIEF) and its relationship to academic functioning. Method: Participants were 991 youth, ages 7 to 17, consecutively referred for neuropsychiatric…

Although several decades of research has highlighted the contribution of classroom behaviors to students' mathematics and reading performance, this relation with regard to writing performance has been examined to a lesser extent. Therefore, this study sought to examine a wide range of classroom behaviors as predictors of written expression,…

Little is known about the characteristics of academic overachievers, children whose achievement significantly exceeds IQ. Correlates of overachievement (achievement test scores = 1 SD above IQ), nondiscrepant achievement, and learning disability (LD; achievement = 1 SD below IQ) were analyzed in 1,543 children (739 ADHD, 285 autism, and 519…

Inter-rater agreement about children's symptoms of attention-deficit/hyperactivity disorder (ADHD) is crucial for accurately identifying and treating children with this condition. Decades of empirical research demonstrate that parents and teachers rarely agree about children's ADHD symptoms, yet few studies have tested the factors that relate to…

More students with attention-deficit/hyperactivity disorder (ADHD) are pursuing higher education. Existing studies have investigated the postsecondary educational outcomes of college students with ADHD, finding that these students typically have lower academic performance and higher dropout rates than their non-ADHD peers. Far fewer studies…

The present study evaluates differences in self-reported intrinsic and extrinsic academic motivation and amotivation between eighth-grade adolescents with (n = 162) and without (n = 140) ADHD. This study also examines associations between motivation and academic functioning with objective (i.e., grade point average, standardized reading and math…

A data-driven, transdiagnostic approach was used to identify the cognitive dimensions linked with learning in a mixed group of 805 children aged 5 to 18 years recognized as having problems in attention, learning, and memory by a health or education practitioner. Assessments included phonological processing; information processing speed; short-term…

This study evaluates a peer-delivered intervention for high school students with impairing attention deficit hyperactivity disorder (ADHD) symptoms targeting organization, time management, and planning (OTP) and motivation (Students Taking Responsibility and Initiative through Peer Enhanced Support; STRIPES). A mixed methods open trial (Study 1; N…

High-functioning children with autism spectrum disorders often find writing challenging. These writing difficulties may be specific to autism spectrum disorder or to a more general clinical effect of attention disturbance, as these children are often comorbid for attention-deficit/hyperactivity disorder (ADHD) symptomatology (and children with…

Objectives/Background: Objectives were to (1) examine previous night's sleep in relation to next day performance on standardized academic achievement and neurocognitive assessments in adolescents, and (2) explore whether previous night's sleep is differentially associated with testing performance for adolescents with and without…

Fifteen third and fourth graders with attention-deficit/hyperactivity disorder were asked to complete reading self-efficacy and reading activity scales and standardized tests of oral and written language to examine the relationships between reading self-efficacy, reading activity, oral language, and reading achievement, with gender and age…

The purpose of this article is to provide the reader with insight into the clinical reasoning involved in the assessment and intervention planning for a child with Attention-Deficit/Hyperactivity Disorder. The reader will be guided through the authors' conceptualization of this case, and suggestions for intervention in the classroom will be…

The Wechsler Intelligence Test for Children -- Fifth Edition (WISC-V) is a comprehensive intellectual ability assessment for children. The WISC-V was developed over the course of five years by an expert team including doctoral-level scientists and clinicians and an advisory panel, who provided expert advice about intellectual ability testing,…

High-functioning children with autism spectrum disorders often find writing challenging. These writing difficulties may be specific to autism spectrum disorder or to a more general clinical effect of attention disturbance, as these children are often comorbid for attention-deficit/hyperactivity disorder (ADHD) symptomatology (and children with…

Students with attention-deficit/hyperactivity disorder (ADHD) often experience a host of negative academic outcomes, and deficits in reading and mathematics abilities contribute to these academic impairments. Students with ADHD may also have difficulties with written expression, but there has been minimal research in this area and it is not clear…
