We investigated how 5th-8th graders' self- and peer-identified withdrawal motivations predicted peer-reported peer relationships and aggression. Participants (N = 221; 47% male) provided self-reports and peer-nomination data (we analyzed 339 students' nominations). We hypothesized shyness, unsociability, and avoidance would predict low peer liking…

The purpose of this sequential mixed methods study was to examine the relationship between classroom climate and student achievement of middle school students. A purposeful sample of 428 middle school students (6th-8th grade) from a large southeastern Texas school district were administered the "Learning Environment Inventory" (LEI) to…

Extensive literature highlights positive outcomes experienced by students whose parents and teachers have strong relationships, but less is known about the factors that influence parent-teacher relationship strength. Using data from "The Impact of Grade Retention: A Developmental Approach," we identify parent-level predictors of the…

This study investigated gender disparities in students' science motivational beliefs, conceptualized as self-concept and intrinsic value, from Grades 4 to 8 in 22 countries. The gender-specific relation between science motivational beliefs and achievement was also scrutinized. Data from the 2011 and 2015 national cohorts of the Trends in…

Using a population-based sample of 1,311 seventh graders in an urban school district in the South Central United States, we examined the associations between early-life trauma, anger regulation, and early adolescent perceptions about sex and parenthood. Girls and boys with more trauma exposure were more likely to perceive adolescent parenthood as…

This study was planned in order to analyze adolescent body image by age and gender, evaluate the relationship between adolescent body image and socio-cultural factors, and determine the extent to which variables such as age, gender, and Body Mass Index (BMI) can serve as predictors of the influential habits and strategies needed to achieve a…

In explaining academic achievement, school climate and social belonging (connectedness, identification) emerge as important variables. However, both constructs are rarely explored in one model. In the current study, a social psychological framework based on the social identity perspective (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) is…

Shy children display wariness in unfamiliar social situations and often experience feelings of social anxiety. This study explored the potential mediating role of cognitive biases in the link between shyness and social anxiety in early adolescence. In particular, we focused on judgments of the probability and cost of negative social situations…

The present paper (1) examined variables, which could predict traditional bullying, cyberbullying, traditional victimization and cybervictimization and (2) looked at persons to examine whether academic, socio-emotional and demographic characteristics differed between traditional, cyber and mixed bullies, victims and bully-victims. A sample of…

As adolescents become increasingly immersed in electronic technologies, popular adolescents may act in similar ways online as they do offline. This longitudinal study employed peer nominations and self-reports to examine perceived popularity and social preference in relation to cyber social behaviors among 256 adolescents during the fall (T1) and…

The self-equilibrium hypothesis underlines the importance of having a strong core self, which is defined as a high and developmentally stable self-concept. This study tested this hypothesis in relation to body image (BI) trajectories in a sample of 1,006 adolescents (M[subscript age] = 12.6, including 541 males and 465 females) across a 4-year…

Social goals are associated with behaviors and adjustment among peers. However, it remains unclear whether goals predict adolescent social development. We examined prospective associations among goals, physical and relational aggression, social preference, and popularity during middle school (N = 384 participants, ages 12-14 years). Agentic…

Prospective longitudinal data from over 14,000 youth residing in 28 communities in the rural United States were analyzed to examine the emergence of mixed-sex friendship groups in early adolescence. Youth were surveyed on 5 occasions between fall of 6th grade and spring of 9th grade. At each assessment, youth reported the names of up to 7…

This study had three goals: (a) assessing the predictive association of externalizing and internalizing behaviors during childhood with sexual onset during early adolescence; (b) examining the interactive link of externalizing and internalizing behaviors with early sexual onset; and (c) investigating the moderating effect of gender in this…

Despite wide recognition of the important role of student bystanders in influencing peer aggression in schools, little is currently known about what influences students to intervene in defense of peer aggression victims. This longitudinal study involving 1,167 primarily white adolescents (aged 12-15 years, 613 females) investigated the role of…
