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…

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…

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…

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,…

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…

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…

Although sluggish cognitive tempo (SCT) is associated with poorer peer functioning, no study has examined SCT in relation to student-teacher relationship quality. The current study examined whether SCT, as rated by both teachers and children, was uniquely associated with poorer student-teacher relationship quality above and beyond child…

Background: The impact of chronic stressors like the COVID-19 pandemic is likely to be magnified in adolescents with pre-existing mental health risk, such as attention-deficit/hyperactivity disorder (ADHD). This study examined changes in and predictors of adolescent mental health from before to during the COVID-19 pandemic in the Southeastern and…

Adolescents with autism spectrum disorder frequently experience social communication difficulties, executive functioning deficits, and anxiety and depressive symptoms, which are similar to the symptoms and correlates of sluggish cognitive tempo. Although sluggish cognitive tempo is related to, but distinct from, the inattentive and…

Adolescence is a developmental period that affords both risk as well as enormous opportunity. Ripple effects can extend far and wide and speak to the nuance and complexity in understanding and treating ADHD during the adolescent period. The studies in this special issue provide novel and important insights into the lives of adolescents with ADHD,…

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%…

Background: Sleep problems are common among adolescents and have a negative impact on functioning. A better understanding of factors that contribute to sleep problems in adolescence can help guide more effective, targeted interventions. Objective: The current study examined the associations between reactive and proactive functions of aggression…

Background: Although multiple cross-sectional studies have shown symptoms of sluggish cognitive tempo (SCT) and attention-deficit/hyperactivity disorder (ADHD) to be statistically distinct, studies have yet to examine the temporal stability and measurement invariance of SCT in a longitudinal sample. To date, only six studies have assessed SCT…

Despite increasing interest in sluggish cognitive tempo (SCT) in children, the field is stymied by the lack of a standard symptom set that can be used across studies. Without a standard symptom set, it is difficult to determine if differences across studies are due to methodological or sample differences, or simply the way SCT was measured. To…
