This study explores the complex dynamics between cyber-ostracism, depression, and cyberbullying among 870 Chinese adolescents (50.9% boys, M[subscript age] = 13.03, SD = 0.76). Using a cross-lagged panel analysis, the results found: (1) bidirectional associations between cyber-ostracism and depression, with cyber-ostracism at Time 1(T1)…

Polysubstance use is related to elevated risk for adverse outcomes but remains understudied among early adolescents. This study focused on a cross-sectional (N = 1568) primarily Black (79%) sample of eighth grade students living in urban communities (Mean age = 13.8, SD = 0.68) to identify subgroups based on adolescents' reports of lifetime and…

The pervasiveness of racism in the U.S. and its negative relations with key development outcomes has led researchers to uncover mediators, of which this article argues efficacy should be considered. Self-efficacy, one's belief in their capability to accomplish a task or goal, can be measured in multiple domains of functioning and contexts to…

Nearly 14 million species are estimated to exist on Earth, of which 1.8 million have been identified, and new species are being added to the world of science every day. Therefore, scientists are aware that there are still unidentified species living globally. Biodiversity is a wide concept encompassing all living things in our living space. This…

An emerging body of research documents a relationship between sleep quantity and delinquency during adolescence. Absent from this line of research, however, is an evaluation of whether the associations between sleep duration and different forms of delinquency vary across periods of adolescence and sex. The current study aimed to address this gap…

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…

Objective: This study examined extracurricular and physical activity related to ADHD (diagnosis and symptoms) and cognitive disengagement syndrome (CDS) symptoms. Methods: Participants were 302 adolescents (ages 12-14) with and without ADHD and primary caregivers. ADHD diagnosis was determined with parent interview. Questionnaires provided…

This study examined post-test performance and retention performance of students in mathematics when learned and problem-solving ability through educational video games and traditional lecture method. The study adopted a quasi-experimental design. The sample was drawn from Alagappa Model Higher Secondary School in Karaikudi at Sivagangai district…

A growing body of research shows that students benefit when they demographically match their teachers. However, little is known about how matching affects social-emotional development. We use student-fixed effects to exploit changes over time in the proportion of teachers within a school grade who demographically match a student to estimate…

Research shows a decline in U.S. adolescent mental health over several decades. It also suggests that higher levels of life satisfaction lead to better mental health outcomes in this population. The purpose of this study was to investigate correlations between adolescent life satisfaction and eight developmental attributes that can be fostered by…

Police stops often perpetuate racial disparities in academic outcomes, yet few studies have examined factors that mitigate these negative consequences. Using two longitudinal studies (Study 1: n = 483, M-age = 12.88, 53% males; Study 2: n = 131, M-age = 15.11, 34% males), this article tests whether parental and school cultural socialization…

The aim of the current study was to examine the role of resilience in the victimization experiences of students and their subjective well-being as well as to explore gender and age-related effects. Initially, 558 students (52.15% male) from grades 6 to 10 participated in the study completing The Student Aggression and Victimization Questionnaire,…

It is unknown whether sluggish cognitive tempo (SCT) is prospectively associated with depression in adolescence, and possible processes linking SCT to depression remain unexamined. Using a longitudinal study with three timepoints over a two-year period, the current study tested the indirect effects of SCT on depression via peer victimization,…

Abundant research has tried to understand how games can be designed and used effectively to improve the learning process and to examine the correlations between digital learning games and student motivation, engagement, and knowledge retention. The current study examined the correlation between learning through digital game-based learning (DGBL)…

Grounded in Self-Determination Theory, this study examined trends in depression and the longitudinal impacts of teacher autonomy support and teacher-student relationships on students' depressive symptoms. A total of 1613 Chinese primary school students (48.17% females) and 1397 Chinese middle school students (47.67% females) completed self-report…
