The heterogeneity in the developmental trajectories of math motivational beliefs (i.e., expectancies for success and subjective task value beliefs) was examined among Asian and Latinx male and female students from Southern California across Grades 8 through 10 (n = 2,710; 50% female; 85% Latinx; 15% Asian; M[subscript age] = 13.77). By conducting…

Youth with greater levels of narcissism face a wide array of difficulties in interactions with others. However, there exists a curious lack of research on their close relationships, such as friendships. In this study, we examined associations between narcissism and friendship features over time. Participants were 261 eighth and ninth graders (112…

Peer victimization is a common concern in adolescence that includes both relational (e.g., exclusion, rumor spreading) and overt (e.g., hitting, threatening) forms (Crick & Bigbee, 1998). Relational and overt peer victimization have shown to be differentially associated with depressive symptoms, with relational peer victimization showing a…

Using data on ninth graders, math teachers, and schools from the nationally representative High School Longitudinal Study of 2009, we investigate the following questions: (1) How do ninth graders' perceptions of their math teachers as equitable relate to their math identity at the intersection of adolescents' race and gender? and (2) Do…

We investigated (1) grade differences in perceived stigma-based peer victimization (SBPV); (2) differences in perceived student and teacher/staff defending against types of SBPV; and (3) whether defending against SBPV affected student subjective wellbeing (SSWB) via anti-victimization school climate perceptions. Participants were 1124 US…

An earlier trial of a school-based, preventative intervention, HealthWise South Africa, demonstrated some efficacy in preventing adolescent drinking and smoking in the Western Cape, South Africa. This was followed by the current implementation trial, which examined how implementation support conditions influenced adolescent drinking and smoking…

This study aimed to investigate whether communication patterns, peers' involvement and gender different can be the predictors of adolescent bullying behavior. This study involved 193 adolescents of grade 8 and 9 with the most adolescents of 14 years old who had filled in questionnaires. The results showed the prevalence of adolescent involvement…

The study tested the hypothesis that there are sex differences in the pathways to mathematical development. Three-hundred and 42 adolescents (169 boys) were assessed in various mathematics areas from arithmetic fluency to algebra across 6th to 9th grade, inclusive, and completed a battery of working memory, spatial, and intelligence measures in…

This study aimed to compare related factors of depressive symptoms among multicultural adolescents in South Korea. Cross-sectional data were collected from 1,325 students studying in ninth grade (mean age: 14.97 ± 0.36 years) who had one Korean parent and one foreign-born parent. The score of depressive symptoms among girls (1.777 ± 0.550) was…

Political education in school is aimed at preparing adolescents for their role as citizens, which comprises political participation as well as political knowledge. While it is generally agreed that basic knowledge about politics is a prerequisite to participation, the specific link between knowledge and participation is left unclear in normative…

Teen dating violence (TDV) and school violence (SV) are two major social problems in adolescence. Until recently, the antecedents of both TDV and SV have been analyzed largely independently of each other. This study analyses and compares the determinants of both TDV and SV, with a focus on physical violence. Based on a comprehensive survey of…

Academic achievement and academic self-concepts are reciprocally related; hence, investigating academic self-concepts should offer a potential approach for gaining a better understanding of immigrant students' (lack of) school success. Proposing that immigrant students' acculturation orientations need to be taken into account, in this study, we…

Secondary school students in the Netherlands already face future-oriented decisions about their educational careers, which are expected to be informed by their interests in specific vocations or occupations. However, vocational interest assessment tools generally do not account for the possibility that students are interested in multiple…

In response to concerns expressed by educational professionals, the researchers developed a quantitative Likert-scale survey to examine the relationships between academic performance (defined as final marks) and recreational video gaming and texting. Questions about video gaming and texting were included with other questions about social…

Background: Rates of PA are low among adolescents living in rural areas. Purpose: The purpose of this study is to measure 1 week of "free-living" PA via accelerometer among 9th- and 10th-grade students who reside in rural Appalachia. A second purpose was to identify gender differences in Social Cognitive Theory (SCT) variables correlated…
