Social support has been consistently identified as a protective factor for youth. Two competing models have been proposed regarding the role of social support: one in which social support provides benefits for all youth (General Benefits) and one where youth undergoing stress are especially protected (Stress-Buffering). While the General Benefits…

Developmental researchers commonly utilize longitudinal data to decompose reciprocal and dynamic associations between repeatedly measured constructs to better understand the temporal precedence between constructs. Although the cross-lagged panel model (CLPM) is commonly used in developmental research, it has been criticized for its potential to…

Valid and reliable teacher ratings serve as the foundation for screening and assessment of youth with behavioral disorders and twin studies offer an opportunity to study those ratings. We conducted a meta-analysis of 15 empirical investigations of aggressive and rule-breaking behavior using teacher ratings in the context of a twin research design.…

There is considerable variability in the extent to which young people with developmental language disorder (DLD) experience mental health difficulties. What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on…

Positive behaviour support (PBS) has become well established as an intervention approach for individuals with intellectual disability and challenging behaviour. However, what remains unexplored is the relationship between PBS and the medical and social models of disability, which historically are the dominant conceptual frameworks put forward in…

The first step for teachers to be efficacious in teaching self-regulated learning (SRL) in their classroom(s) is to have clear understandings of what constitutes SRL and when to use it. This study examined how K-12 teachers (N = 128, 73% female, predominantly Caucasian) define SRL and identify students with deficient SRL by examining their…

Schools have poor reputation among creativity researchers. Teachers' biases and implicit theories, disruptive behaviors among creative students, and the equivocal pattern of the relationship between creativity and school achievement all contribute to this fact. This chapter presents a new typological model of creativity and demonstrate how this…

This article aims to provide a critical analysis of how much we know about the effectiveness of parental monitoring in preventing adolescent delinquency. First, it describes the historical developments in parental monitoring research. Second, it explains why it is uncertain whether causal inferences can be drawn from contemporary research findings…

The Dual Failure Model suggests that peer victimization (social failure) and academic difficulties (academic failure) mediate the association between externalizing and later internalizing problems. The present study sought to better understand why children with externalizing problems develop later internalizing problems by testing the Dual Failure…

Background: Comorbid psychopathology and stress were considered possible mediators that may explain the relationship between some autistic traits and repetitive behaviours. The current study sought to examine the mediational effects of comorbid psychopathology, executive dysfunctions and stress in the relationship between some autistic traits and…

Research on the role of puberty in adolescent psychological development requires attention to the meaning and measurement of pubertal development. Particular questions concern the utility of self-report, the need for complex models to describe pubertal development, the psychological significance of pubertal timing vs. tempo, and sex differences in…

The purpose of the present study was to investigate the existing transactional associations between mother-child conflict and the child's internalising and externalising problems. To this end, longitudinal data were used, covering ages 7-15. The sample consisted of 1,136 mothers and their children who participated in the National Institute of…

Perfectionism can influence how one approaches challenges and deals with setbacks, and, consequently, can inhibit or facilitate achievement. The present study (1) explored the relationship between Frost's six dimensions of perfectionism and five types of coping strategies; (2) examined how dimensions of perfectionism predict coping in response to…

The purpose of this study was to determine whether a relationship existed between teacher perception of a school's behavior management program and the implementation process. This study explored perceptions of teachers from three aspects of the Positive Behavior Intervention Support model as they relate to the implementation processes for PBIS.…

Adolescence and early adulthood is a time when peer groups become increasingly influential in the lives of young people. Youths exposed to deviant peers risk susceptibility to externalizing behaviors and related psychopathology. In addition to environmental correlates of deviant peer affiliation, a growing body of evidence has suggested that…
