There are few studies of behavior problems in preterm children prior to 2 years old and the changes that occur over time. The aims of this study were to examine the patterns and prediction of behavior problems and the effects of gender and socioeconomic status (SES) on behavior problems in preterm children at the toddler and preschool periods.…

The present study examined adolescents' and mothers' temperament types and their roles in the socioemotional functioning of early adolescents. A total of 869 sixth-grade students and 668 mothers participated in the study. The students rated their temperament and socioemotional functioning and the mothers rated their own temperament. Latent profile…

The purpose of this research was to determine the influence of two subcomponents of auditory short-term memory on the developmental trajectories of behavior problems. The sample included 7,058 children from the NLSY79--Children and Young Adult survey between the ages 5 and 14 years. Results suggested that anxious/depressed behavior increases…

Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting,…

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total…

Previous studies have reported that children from single-parent households fare worse behaviorally than those from two-parent households. Studies examining single-parent households often fail to distinguish between single-mother and single-father households. Further, there are inconsistent findings regarding the effect of family structure on boys…

Attention-Deficit/Hyperactivity Disorder (ADHD) has been linked to disruptive behavior and disciplinary consequences; however, the variables involved in this process are largely unknown. The current study examined rule-breaking behavior as a mediator of the relation between ADHD symptoms and disciplinary actions 1 year later during after-school…

We examined inattention/overactivity (I/O) over time and in relation to caregiving in three matched groups: (1) Romanian Orphans (RO) with a minimum of eight months' deprivation prior to adoption, (2) Early Adopted (EA) children adopted from Romania prior to age four months, and (3) Canadian Born (CB) non-adopted children. Comparisons among groups…

This study estimates the causal effects of six corrective actions for children's problem behaviors, comparing four types of longitudinal analyses that correct for pre-existing differences in a cohort of 1,464 4- and 5-year-olds from Canadian National Longitudinal Survey of Children and Youth (NLSCY) data. Analyses of residualized gain scores found…

This study examined links between paternal and maternal parenting factors and preschool hyperactivity in a community sample. Forty-one hyperactive and 38 comparison boys (aged 47-62 months) and their fathers and mothers were assessed on a range of interview, parent questionnaire, and observational measures of parenting and child behavior. Results…

Canadian data based on maternal reports for a nationally representative sample of 4,521 4-5-year-olds were used to examine associations among child care, family factors, and behaviors in preschool-aged children. Linear regressions testing for direct and moderated associations indicated that regulated home-based care was associated with less…

Behavioral problems are frequent among post-institutionalized Eastern European adoptees. However, risk factors related to outcomes have not been fully delineated. We evaluated 50 Eastern European adoptees, age 8-10 years, with their adoptive families for more than five years. Cognitive and behavioral outcomes and parenting stress were evaluated in…

The aim of this study was to examine whether there was variation in levels of psychological adjustment among children conceived through Assisted Reproductive Technologies using the parents' gametes (homologous), sperm donation, egg donation, embryo donation and surrogacy. Information was provided by parents about the psychological functioning of…

Aggressive behavior in childhood has long been separated into that which is proactively motivated and that which is reactive. We report a meta-analytic review of the existing empirical literature that examines the associations of each type of aggression with six indices of psychosocial adjustment: internalizing problems, emotional dysregulation…

Studied patterns of boys' social development by examining data from two longitudinal studies: a Finnish study of eight year olds begun in 1968; and a French Canadian study of six year olds begun in 1984. Patterns were identified using variables of aggression, hyperactivity, inattentiveness, anxiety, and lack of prosocial behavior. (LB)
