Students who are not motivated and do not try to do well are unlikely to achieve consistent with their abilities. This research assesses the relationships over time between school engagement and parenting practices and peer affiliation among sixth to ninth graders using latent growth models. Participants included 2,453 students recruited from…

Our study of 477 children with autism (1-15 years, IQs 9-146) showed that parent reported sleep problems are found in most children with autism and are not significantly related to age, IQ, gender, race, parent occupation, neuropsychological functioning, and learning ability. However, sleep problems increased with severity of autistic symptoms and…

As limited research exists on medical students' substance use patterns, including over-consumption of alcohol, the objective of this study was to determine prevalence and correlates of at-risk drinking among a national sample of medical students, using a cross-sectional, anonymous, Web-based survey. A total of 2710 medical students from 36 U.S.…

The objectives of the study were to examine the characteristics of non-referred children with behaviour difficulties (BD) (such as verbal and physical aggression towards children and objects), aged 9-12 years and attending mainstream schools, and to compare them with children with no BD. The second objective was to evaluate the contribution of a…

Public schools have historically embedded mechanisms for control within their policies and procedures through a variety of means. This article investigates a moderately sized integrated public school system in an upscale to low socioeconomic Big Ten university community in Illinois. Through descriptive measures, the author examines the racial…

This study assessed gender differences in cognitive variables as an explanation for gender differences in depression and behavior problems; 856 adolescents (491 females and 365 males), aged 14-17, completed the Irrational Beliefs Scale for Adolescents, the Social Problem Solving Inventory--Revised Short Form, the adolescent version of the Burnett…

The current research is among the first to examine whether gender or the level of competitiveness affects a person's motivation to gamble. One hundred fifty two participants completed a scale to measure whether they were intrinsically or extrinsically motivated to gamble (Gambling Motivation Scale) and a scale to measure their level of…

Effects of parents' divorce on children's adjustment have been studied extensively. This article applies new advances in trajectory modeling to the problem of disentangling the effects of divorce on children's adjustment from related factors such as the child's age at the time of divorce and the child's gender. Latent change score models were used…

Many social interactions between school-age children contain both competitive and cooperative elements. In order to gain a better understanding of how students at risk for emotional and behavioural difficulties (EBD) negotiate social exchanges in cooperative and competitive-related tasks in comparison with non-EBD students: (a) prosocial; (b)…

Adolescence is often thought of as a period during which the quality of parent-child interactions can be relatively stressed and conflictual. There are individual differences in this regard, however, with only a modest percent of youths experiencing extremely conflictual relationships with their parents. Nonetheless, there is relatively little…

This study used sampling survey data from rural elementary schools in western China to analyze school adaptability, which is the representative noncognitive development of rural elementary students. It also investigated factors influencing the school adaptability of elementary school students at an individual and school level by using production…

A review is provided of recent research literature on the topic of troublesome classroom behaviour, published over the past decade or so with particular reference to research carried out in Australian schools. Nine Australian studies are reviewed, as well as a further seven from the USA, Hong Kong, Jordan, Greece and Malta. Seven of the studies…

The current 5-year accelerated longitudinal investigation modeled the developmental trajectories of aggressive behaviors in 10,107 predominantly minority (greater than 70%; African American, American Indian, Asian American, and Hispanic) children and early adolescents (Kindergarten through 8th grade, 49% female youth) from lower to lower-middle…

We examined anger rumination and sadness rumination in clinic-referred adolescents (N = 121). Factor analysis indicated that items from analogous anger and sadness rumination measures loaded onto 2 factors tapping anger rumination and sadness rumination, respectively. Structural equation modeling confirmed unique relations between each form of…

This study investigated both relational and physical aggression in preschool children, explored potential differences in informant reporting and child sex on these subtypes, and examined relationships between types of aggressive behaviors and other types of negative and positive social behaviors. Naturalistic observations of social behavior,…
