Objective: The objective of this study was to compare caffeine consumption in the morning, afternoon, and evening in adolescents with and without ADHD and examine associations with sleep functioning. Methods: Participants were 302 adolescents (ages 12-14) with (n=140) and without (n=162) ADHD. Adolescents wore actigraph watches to assess total…

Introduction: This study examined whether adolescents with and without attention-deficit/hyperactivity disorder (ADHD) differed in affect variability and whether variability in positive and negative affect was associated with functional outcomes. Method: Participants were 302 adolescents (12-14 years, "M"age=13.17, 55% male; 54%…

Purpose: To examine remote learning practices and difficulties during initial stay-at-home orders during the COVID-19 pandemic in adolescents with and without ADHD. Methods: Participants were 238 adolescents (132 males; 118 with ADHD) ages 15.64-17.99 years and their parents. Adolescents and parents completed questionnaires in May/June 2020 when…

Objectives: This study used a multi-informant approach to examine differences in types and rates of technology used by adolescents with and without attention-deficit/hyperactivity disorder (ADHD), associations between technology use and sleep/daytime sleepiness, and whether technology use was differentially related to sleep/daytime sleepiness in…

Background: Prior studies examining the sleep of adolescents with and without attention-deficit/hyperactivity disorder (ADHD) have relied on mean values such as average sleep duration, which masks intraindividual variability. The objective was to investigate whether adolescents with ADHD have greater intraindividual variability of sleep/wake…

Background: Children with attention-deficit/hyperactivity disorder (ADHD) experience greater sleep problems than their peers. Although adolescence is generally a developmental period characterized by insufficient sleep, few studies have used a multi-informant, multi-method design, to examine whether sleep differs in adolescents with and without…

The Positive and Negative Affect Schedule (PANAS) has been widely used to assess affect expression. Shortened and adolescent versions of the measure have been created, such as the 10-item PANAS for Children (PANAS-C). However, affect expression often involves substantial intraindividual variability, and no research has examined within-person…

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…

Emotion dysregulation is associated with attention deficit/hyperactivity disorder (ADHD) and confers risk for behavior problems and functional impairment; however, there is little guidance on best practices for measurement in adolescents. We developed a parent-report version of the Difficulties in Emotion Regulation Scale (DERS-P)). Evidence of…

Objective: The primary objective of this study was to evaluate the prevalence of multiple types of sleep problems in young adolescents with ADHD. Method: 262 adolescents comprehensively diagnosed with ADHD and their caregivers completed well-validated measures of sleep problems and daytime sleepiness. Participants also completed measures related…

Interest in understanding the association between attention-deficit/hyperactivity disorder (ADHD) and sleep is nothing new. In fact, restless sleep was a symptom criterion for attention deficit disorder in the Third Edition of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-III), and the negative impact of inadequate or…
