Childhood adversity takes a toll on lifelong health. However, investigations of unpredictability as a form of adversity are lacking. Environmental unpredictability across multiple developmental periods and ecological levels was examined using a multiethnic, longitudinal birth cohort (1998-2000) oversampled for unmarried parents. Data were from the…

Restricted interests and repetitive behaviors (RRBs) are core symptoms of autism spectrum disorder (ASD), and commonly occur in attention-deficit/hyperactivity disorder (ADHD). Little is known about how RRBs manifest in ADHD. We quantified and compared factor structures of RRBs in children with ASD (n = 634) or ADHD (n = 448), and related factors…

Purpose: Reported ear and hearing difficulties (rEHD) are known to be associated with reading difficulties as well as mental health problems. In this study, we aim to examine the relationship between reading and mental health in children with rEHD. Method: In this study, we used structural equation modeling to measure the strength of longitudinal…

Diverse mechanisms account for the familial aggregation of certain personality traits and externalizing psychopathology. We explored the roles of positive and negative parenting as mediators of longitudinal associations between parents' maladaptive personality traits and their children's inattention/hyperactivity problems. We collected self,…

Individuals with attention problems often exhibit more off-task behaviors and less engagement in classroom settings, and exercising has demonstrated positive effects in decreasing disruptive behaviors and increasing on-task behaviors. The purpose of this study was to examine the effects of physical activity on academic engaged time for individuals…

Poor reading has been linked to negative outcomes on a wide range of emotional-behavioural dimensions in children. However, little is known about the time course of these associations. In this study we analyse data from a sample of Finnish children (N = 199; 106 boys) which included measures of reading fluency in grade 1 (age 7 or 8), and…

The dysregulation profile (DP) in youth is characterized by severe emotional, cognitive, and behavioral dysregulation and is associated with an increased risk for psychiatric disorders. Adolescent self-regulation has important implications for adulthood outcomes, yet this association is understudied in the context of the DP in emerging adults.…

In this study, we examined trajectories of specific domains of behavior problems (i.e., attention problems, depression/anxiety, and aggressive behavior) from age 6 to 18 in a sample of 55 children with fragile X syndrome. We also examined autism status and early parenting as predictors of subsequent behavioral trajectories. We found that attention…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

The social validity of behavior intervention is rooted in consumer perception. This information is typically garnered through questionnaires and interviews conducted with relevant consumers such as teachers or caregivers. Often, the participants (i.e., the individuals with disabilities receiving the intervention) play less of a role in the…

The purpose of the study was to assess early literacy skills and examine the presence and stability of challenging behaviors across the critical threshold of the kindergarten school year. Students' (n = 337) literacy performance (letter sound fluency, word attack, and phonological awareness) and challenging behaviors (teacher ratings of…

Background: In children, internalizing and externalizing problems impact on learning. However, there is limited research on the specific impact of such problems on spatial working memory (SWM), strongly related to cognitive ability and children's learning. Aims: We explored distinct trajectories of internalizing problems and externalizing problems…

This study examines the cost effectiveness of two interventions for disruptive behavior problems: First Step Next (FSN), a school-based intervention, and a multicomponent intervention that combined FSN with a home-based intervention, homeBase (hB). Analyses were based on findings from a large-scale comparative efficacy trial in the United States…

Objective: ADHD is a prevalent neurodevelopmental disorder characterized by symptoms of inattention and hyperactivity-impulsivity. Impairments in executive functioning (EF) are central to models of ADHD, while alpha-band spectral power event-related decreases (ERD) have emerged as a putative electroencephalography (EEG) biomarker of EF in ADHD.…

Purpose: Avoidant automatic thoughts (AAT) are thoughts that precede or accompany a delay in the starting or ending of a task. In a prior study of college students using Ecological Momentary Assessment (EMA), AATs were frequent daily occurrences and participants with more severe ADHD symptoms at baseline reported more frequent AAT. Importantly,…
