Previous studies have examined the relationship between sleep problems and challenging behaviors in school-aged children and adolescents with autism spectrum disorder (ASD). However, literature has not examined this relationship in the context of toddlers or, more specifically, toddlers with aggression. The present study was conducted to examine…

With the explosive growth in time spent on YouTube by babies and toddlers, it's important to analyze what they're watching on YouTube. Indexes that evaluate the contents of YouTube channels for infants and toddlers have been developed, but since those were evaluation-based indexes of educators and parents, it is difficult to find out what content…

The present study explored the association between the structural quality of child care, caregivers' sensitive responsiveness, children's involvement in play and activity in the setting, and children's expression of aggression. Eighty-four early childhood care settings were classified into either high (29) or low structural quality (55) based on…

Attention deficit/hyperactivity behaviors in children are often unnoticed until they reach school age; however, evidence suggests that attention deficit hyperactivity disorder (ADHD) tends to develop at an earlier age. Recent studies also indicate that perinatal maternal mental health is associated with ADHD symptoms in offspring. This study…

Autism spectrum disorder (ASD) frequently co-occurs with additional symptoms of psychopathology and challenging behaviors. While aggressive behaviors are often associated with attention deficits and hyperactivity in children with ASD, there is limited research on the impact that inattention/impulsivity and aggressive behaviors have on the…

The present study examined the psychometric properties of a brief parent-report daily checklist of toddler behavior (Parent Daily Report--Toddler Version; PDR-T). Data were collected from three groups of 18-36 month-olds who were followed longitudinally for approximately one year: (a) internationally adopted children (N = 156); (b) children placed…

This study examined the reciprocal associations between sleep (duration and quality) and aggressive behavior in toddlers. The sample consisted of 82 children (43 boys and 39 girls) and their parents who completed two assessments, when children were 2 and 3 years old. At both time points, children wore an actigraph for 3 consecutive days to assess…

This study examined the links between mothers' and fathers' emotion socialization practices and social behaviour between siblings. We utilized parent reports from 57 two-parent families with preschool- and toddler-aged siblings to assess parental responses to children's negative emotions, as well as siblings' engagement in positive involvement,…

Women are at greater risk of exposure to interpersonal violence during pregnancy. The influence prenatal violence has on children's behavioral adjustment is generally understood to stem from its impact on mothers, but there is a dearth of prospective research to test these models. The current study evaluated the influence of interpersonal violence…

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically…

We tested the hypothesis that developmental precursors to aggression are apparent in infancy. Up to three informants rated 301 firstborn infants for early signs of anger, hitting and biting; 279 (93%) were assessed again as toddlers. Informants' ratings were validated by direct observation at both ages. The precursor behaviours were…

This article describes Prevent-Teach-Reinforce for Young Children (PTR-YC), a model based on extensive research that is designed for feasibility and effectiveness for treating challenging behaviors in classroom settings. This model is designed to meet the needs of children with and without disabilities who engage in challenging behavior that…

Research Findings: Within the flourishing area of research demonstrating the efficacy of emotion-based interventions carried out by trained teachers in educational contexts in increasing children's emotional skills, this study makes an original contribution to the existing literature by focusing on the effects of this kind of intervention on…

Research Findings: We examined relations of effortful control with parent emotion socialization practices and child social behavior using a person-centered approach in children ages 18 months to 5 years. A total of 76 parents (66 mothers, 10 fathers) completed questionnaires at screening and 6-month follow-up. There were no age differences in…

This paper describes the development, implementation and preliminary evaluation of the Reaching Educators and Children (REACH) program, a training and coaching intervention designed to increase the capacity of early childhood teachers to support children's social and emotional development. We evaluated REACH with 139 teachers of toddler and…
