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…

Universal screening is a useful way to identify emotional and behavioral problems and develop prevention or intervention strategies for adolescents at-risk in schools. The purpose of the present study is to report the preliminary development and validation of a brief and effective instrument--the Youth Externalizing Behavior Screener (YEBS)--aimed…

Socioeconomic disadvantage is associated with social-emotional difficulties, including internalizing and externalizing problems, as early as toddlerhood. The aim of the current study was to understand whether economically disadvantaged children's beliefs about the consequences and correlates of poverty (poverty stereotypes) and their beliefs about…

The population of Canadian schools is becoming increasingly diverse in ethnic origins. Despite the challenges they face, paradox immigrant theory suggests that immigrant students have a more favorable profile than their non-immigrant peers in terms of academic success. The aim of this longitudinal study which was conducted with 66 elementary…

The current study examined the feasibility and initial efficacy of the Summer Treatment Program for Pre-kindergarteners (STP-PreK) with 37 preschoolers with autism spectrum disorder (ASD) and externalizing behavior problems (EBP). Parents and teachers reported on children's behavior, social/adaptive skills, and self-regulation. Children completed…
