Multi-informant Examination of Cognitive Disengagement Syndrome in Relation to Sleep and Circadian Preference in Early Adolescents
Considerable research has documented an association between attention-deficit/hyperactivity disorder (ADHD) and poor sleep functioning, yet few studies have examined the potential role of frequently co-occurring cognitive disengagement syndrome (CDS). Further, extant studies have used non-optimal measures of CDS and/or sleep, small sample sizes, or rarely focus on adolescence when sleep problems often emerge and worsen, and few have controlled fo…
Neonatal brain abnormalities predict preschool executive functioning performance in children born very preterm
Children born prematurely consistently exhibit deficits on performance-based and caregiver-report measures of executive functioning (EF). As early EF may mediate premature childbirth's impact on neurodevelopmental and behavioral outcomes, it is important to understand risk factors for EF deficits. Data from a longitudinal prospective cohort study were used to explore the association of brain abnormalities with EF measures in very preterm children…
An In‐Depth Examination of Learning Behaviors in Autistic Middle‐Schoolers Without Intellectual Disability
Autistic students demonstrate poor academic performance which may be related to challenges in learning behaviors such as organization, planning, study skills, and so forth. Most studies report on summary scores; however, there may be value in understanding specific strengths and challenges to better inform assessment and intervention efforts. The aim was to assess the profile of learning behaviors in autistic students and the impact of an interve…
Cognitive disengagement syndrome and depressive symptoms in early adolescents: Examining the moderating role of a negative interpretation bias
BACKGROUND: Despite previous research demonstrating an independent association between cognitive disengagement syndrome (CDS; previously termed sluggish cognitive tempo) and depressive symptoms, studies have yet to examine what factors may moderate this link. A negative interpretation bias (i.e., maladaptive information processing whereby emotionally aversive meaning is perceived in ambiguous situations) is associated with the development and mai…
Is Temperament Associated with Academic School Readiness in Children Born Very Preterm
Research Findings: Temperament, which can be assessed as early as three months, is associated with school readiness and later academic achievement in children born full term. Although children born preterm demonstrate a dysregulated temperament and are at significant risk for lower school readiness, we found no studies investigating whether early temperament is associated with school readiness in this at-risk population. Investigating whether tem…
Examining Narcissistic Traits in Relation To Reactive and Proactive Aggression in Children At-Risk for Attention Deficit/Hyperactivity Disorder
The current study examined narcissistic traits in relation to proactive and reactive functions of aggression in a sample of children at-risk for attention-deficit/hyperactivity disorder (ADHD). Children ages 7-13 years (N = 110) were recruited from a pediatric ADHD assessment clinic. Caregivers completed the Antisocial Process Screening Device. Caregivers and teachers completed a measure of proactive and reactive aggression. In regression analyse…
Academic functioning in children with and without sluggish cognitive tempo
The Association of Executive Functioning With Academic, Behavior, and Social Performance Ratings in Children With ADHD
This study investigated the association of a performance-based measure of executive functioning (EF) with academic, social, and behavioral performance ratings in a convenience sample of 153 children aged 5 to 12 (78% male, 83% Caucasian) diagnosed with attention-deficit/hyperactivity disorder (ADHD). Multivariate regression showed that above and beyond age and ADHD severity, poorer EF performance was uniquely associated with more impairment in re…
Analysis of structural brain asymmetries in attention‐deficit/hyperactivity disorder in 39 datasets
OBJECTIVE: Some studies have suggested alterations of structural brain asymmetry in attention-deficit/hyperactivity disorder (ADHD), but findings have been contradictory and based on small samples. Here, we performed the largest ever analysis of brain left-right asymmetry in ADHD, using 39 datasets of the ENIGMA consortium. METHODS: We analyzed asymmetry of subcortical and cerebral cortical structures in up to 1,933 people with ADHD and 1,829 una…
Impact of sleep restriction on affective functioning in adolescents with attention‐deficit/hyperactivity disorder
BACKGROUND: Shortened sleep and affective disturbances are both prevalent in adolescents with attention-deficit/hyperactivity disorder (ADHD), yet the causal link between these domains has not been examined. This study investigated whether shortened sleep duration is causally linked to affective functioning in adolescents with ADHD. METHODS: Participants were 48 adolescents (75% male) aged 14-17 years with ADHD who successfully completed a three-…
