Objectives/Background: This study examined whether dispositional mindfulness moderates the association between brooding rumination and sleep problems in adolescents with and without attention-deficit/hyperactivity disorder (ADHD). Participants/Methods: Participants were 137 adolescents (ages 13-15 years; 64% male). Approximately half (47.4%; n=65)…

The Adult Concentration Inventory (ACI) is an adult self-report measure of sluggish cognitive tempo (SCT) developed following a meta-analysis identifying items distinguishing SCT from ADHD inattention. To date, only one study conducted in college students has examined the structural and external validity of the ACI. The current study evaluated the…

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…

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…

A growing number of studies support the internal and external validity of youth self-reported sluggish cognitive tempo (SCT) symptoms. However, no study has examined SCT in adolescents without ADHD, examined whether adolescent self-reported SCT is distinct from adolescent self-reported ADHD inattention (ADHD-IN), or evaluated whether links between…

Objective: College students with attention deficit/hyperactivity disorder (ADHD) are at increased risk for numerous educational and psychosocial difficulties. This study reports findings from a large, multisite randomized controlled trial examining the efficacy of a treatment for this population, known as ACCESS -- Accessing Campus Connections and…

A growing body of research demonstrates that school climate is associated with adolescent mental health. Much of the extant literature have focused on identifying risk factors for adverse mental health outcomes, whereas much less work has been done examining factors that are important to foster adolescents' strengths and thereby increase the…

Study Objectives: To prospectively examine changes in adolescent sleep before and during the COVID-19 pandemic in adolescents with and without ADHD. Methods: Participants were 122 adolescents (ages 15-17; 61% male; 48% with ADHD). Parents reported on adolescents' sleep duration and difficulties initiating and maintaining sleep (DIMS); adolescents…

It is unknown whether sluggish cognitive tempo (SCT) is prospectively associated with depression in adolescence, and possible processes linking SCT to depression remain unexamined. Using a longitudinal study with three timepoints over a two-year period, the current study tested the indirect effects of SCT on depression via peer victimization,…

Addressing the complex homework and organization problems faced by students with attention-deficit/hyperactivity disorder (ADHD) must be balanced with ensuring that interventions are feasible to implement. The Homework, Organization, and Planning Skills (HOPS) intervention was developed to be a brief intervention implemented in typical school…

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…

Objective: Although peer difficulties and sluggish cognitive tempo (SCT) are related, studies have yet to examine environmental factors that may advance further understanding this association. The current study tested whether peer difficulties, specifically social competence and peer victimization, interacted with school support, a component of…

Objective: The present study evaluated the prevalence of past suicidal ideation (SI), plan, and attempt in college students with ADHD (N = 102) compared to a matched control (N = 102). Predictors of SI, plan, and attempts, were examined. Participants: Study participants were first year college students at a large Southeastern university who…

This study examined whether the association between cybervictimization and internalizing symptoms was moderated by adolescents' emotional connectedness to their social media. Participants were 288 adolescents (54.9% male participants) with (n = 151) and without (n = 137) attention-deficit/hyperactivity disorder (ADHD) between the ages of 13 and 15…

Adolescents with Attention-deficit/hyperactivity disorder (ADHD) experience significant impairment in functioning. There are multiple clinic-based interventions that address these impairments (e.g., behavioral parent training). However, clinic-based interventions are often associated with barriers to care (e.g., transportation and financial…
