The present three-wave panel study (N = 973, X-bar[subscript age] = 11.14) sought to advance the current literature on media internalization in preadolescence by examining triggers and consequences related to preadolescents' media internalization and use of media for appearance information. We sought to examine whether (a) media internalization…

In this study, we tested two competing explanations of the previously established link between early female puberty and sexual harassment in early adolescence. The sample included 680 seventh-grade Swedish girls (M[subscript age] = 13.40, SD = 0.53). Findings revealed that looking more sexually mature and being sexually active mediated the link…

Individuals with autistic traits are considered to be prone to develop psychosexual problems due to their limited social skills and insight. This study investigated the longitudinal relation between autistic traits in childhood (T1; age 10-12 years) and parent-reported psychosexual problems in early adolescence (T2; age 12-15 years). In a general…

Multiple informants commonly disagree when reporting child and family behavior. In many studies of informant discrepancies, researchers take the difference between two informants' reports and seek to examine the link between this difference score and external constructs (e.g., child maladjustment). In this paper, we review two reasons why…

We investigated longitudinal predictors for disordered eating from early adolescence to young adulthood (12-34 years) across gender and different developmental phases among Norwegian young people. Survey data from a population-based sample were collected at four time points (T) over a 13-year time span. A population-based sample of 5,679 females…

The often observed decline in students' self-perceptions across transition to secondary school after grade 6 is often attributed to students' entry to puberty. This study aims to examine whether lowered self-perceptions can be observed after transition in Germany which occurs after grade 4 and thus takes place before puberty. Fifth graders (N =…

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…

Some pupils already show unexcused, illegal, surreptitious absences in elementary education or the first years of secondary education. Are weak social bonds (see also Hirschi, 1969) and a lack of self-control (Gottfredson & Hirschi, 1990) indicative of truancy at an early age? Of the children in our sample, 5% were persistent truants in late…

The connection between pubertal stage and the development and depressive symptoms among females is investigated. Findings reveal that advancing pubertal stage presents greater risks for the beginning and persistence of depressive symptoms among females. The impacts of social adversity on the persistence of symptoms for female depression.

The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer…

Objective: To investigate overweight prevalence and socio-demographic and economic correlates in Chinese adolescents. Methods: Weight, height, waist circumference, and socio-demographic and economic variables of 6863 middle and high school students were measured. Results: 10% of girls and 17% of boys were overweight. Waist circumference and…

Investigated the effects of pubertal timing, demographics, family processes, and leisure activities on the timing of first sexual experience among adolescents (N=702). Higher levels of parental monitoring predicted later initiation of sexual experience for most participants. Higher levels of risky leisure also predicted earlier first sexual…

Previous research has indicated that pubertal development and the transition from middle or elementary school to junior high may present problems for some preadolescents. The effects of these transitions on achievement, psychological well-being, and social relations were examined using data from the National Longitudinal Survey of Children and…

The role of biological maturity in behaviors in adolescents which most often are considered as negative by adults was investigated for a normal group of girls. (Author/LMO)

Risk factors for early adolescents' (700 between the ages of 10 to 13) delinquency were compared between groups of children high and low in childhood adversities. The samples represented young people from the two former Germanies (200 from former East and 500 from West Germany) who were interviewed in person. Additional information was gathered…
