Multiple sleep problems have been reported in children with Autism Spectrum Disorder (ASD). The association of poor sleep with problematic daytime behaviors has been shown in small studies of younger children. We assessed the relationship between sleep and behavior in 1784 children, ages 2-18, with confirmed diagnosis of ASD participating in the…

Aggressive victims--children who are both perpetrators and victims of peer aggression--experience greater concurrent mental health problems and impairments than children who are only aggressive or only victimized. The stability of early identified aggressive victim status has not been evaluated due to the fact that most studies of aggressor/victim…

Background: DSM-IV specifies three ADHD subtypes; the combined, the hyperactive-impulsive and the inattentive. Little is known about the developmental relationships underlying these subtypes. The objective of this study was to describe the development of parent-reported hyperactivity-impulsivity and inattention symptoms from childhood to…

Stimulant drugs (methylphenidate and amphetamine) have been used successfully for decades to improve the behavioral impairments of hyperactivity, impulsivity, and inattention in children diagnosed with attention-deficit/hyperactivity disorder (ADHD). A voluminous literature supports the benefits of stimulants for improving classroom manageability…

Intentional self-regulation is a core facet of human functioning, involving people's modulation of their thoughts, attention, emotions, and behaviors to react to environmental demands and to influence their own development. Using data from Grades 8, 9, and 10 of the 4-H Study of Positive Youth Development (PYD), the structure of intentional…

Objective: As a follow-up to an earlier cross-sectional study (Holmbeck et al., 2003), the current multimethod, multi-informant investigation examined individual growth in psychosocial adjustment across the adolescent transition in 2 samples: young adolescents with spina bifida (SB) and typically developing adolescents (N = 68 in both groups at…

Evidence that childhood maltreatment is associated with emotional and behavioral problems throughout childhood suggests that maltreatment could lead to impaired academic performance in middle and high school. This article explores these effects using data on siblings. An index measure of the intensity of childhood maltreatment was included as a…

Similar to the state of the broader intellectual disabilities field, many gaps exist in the research and treatment of mental health concerns in people with Down syndrome. This review summarizes key findings on the type and prevalence of behavior and emotional problems in children, adolescents, and adults with Down syndrome. Such findings include…

This paper investigates the determinants and malleability of noncognitive skills. Using data on boys from the National Education Longitudinal Survey, I focus on youth behavior in the classroom as a measure of noncognitive skills. I find that student behavior during adolescence is persistent. The variation in behavior can be attributed to…

The present study was designed to define the relationship between the supposed syndrome of hyperactivity and that of aggressive conduct disorder. (Author/DB)

Two experiments were implemented in which hyperactive children were exposed to models of their own age level. It was hypothesized that modeling treatments designed to demonstrate reflective problem-solving strategies would improve the problem-solving ability of both normal and hyperactive children, and that, concomicantly, children's ability to…

Negative emotionality and poor attention may combine or interact as risk factors in development. Negative emotionality is considered a challenge for self-regulation, whereas good attention is a potential means of self-regulation. In the current study, composites of 1- and 2-year maternal ratings of negative emotionality and global ratings of…
