This study examined how adolescents' emotions in mathematics develop over time. Growth curve modeling was applied to longitudinal data collected annually from 2002 to 2006 (Grades 5-9; N = 3425 German adolescents; M[subscript age] = 11.7, 15.6 years at the first and last waves, respectively; 50.0% female). Results indicated that enjoyment and…

The aim of the study was to explore same-sex and opposite-sex friendship functions among 12 to 13- and 16 to 17-year-old Hungarian adolescents (n = 304). To explore perceptions of friendship functions, the McGill Friendship Questionnaire (MFQ, 30 items, 6 factors: stimulating companionship, help, intimacy, reliable alliance, self-validation,…

Three studies were conducted to examine what factors were associated with expected bystander intervention across two different contexts (i.e., online and offline), two different age groups (i.e., adolescence and young adulthood) and three different forms of victimization (i.e., general cyberbullying, gender-based cyberbullying, and gender-based…

The study aimed to develop and evaluate the psychometrical properties of a new brief measure of gender stereotyping career attitudes. Participants were 222 early and 196 middle adolescents from Croatia. The Vocational Gender Stereotype Attitudes Scale (VGSA) consists of 12 items that represent masculine, feminine and gender-balanced activities…

Despite growing calls for greater inclusivity and cultural responsiveness, little is known about how environmental education (EE) may differentially affect diverse audiences. As part of a national study of 334 environmentally focused day field trips for adolescent youth in the United States in 2018, we examined how outcomes differed for students…

Youth victimization and aggression are common in adolescents' everday lives. This study examines relations between youth cognition and reasoning around bullying and possible responses to bullying, peer nominations related to youth roles in the bullying ecology and self-report experiences of perceived racial discrimination using latent class…

This study investigated trajectories of individual and vicarious online racial discrimination (ORD) and their associations with psychological outcomes for African American and Latinx adolescents in 6th-12th grade (N = 522; "M"[subscript grade] = 9th) across three waves. Data were analyzed using growth mixture modeling to estimate…

Research findings indicate a decline in students' motivation towards science learning through grade levels. However, there is a lack of studies investigating students' motivation comparing learning between science subjects and at different school levels. Using self-determination theory as a framework, this study compares perceived changes in…

Antisocial peer behavior and low parental knowledge of adolescents' activities are key interpersonal risk factors for adolescent substance use. However, how the magnitude of associations between these risk factors and substance use may vary across adolescence remains less well understood. The present study examined the age-varying associations of…

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 (M = 11.21 years) to Grade 10 (M = 16.25 years) provided self-reports of delinquency. Friendships were identified from…

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

There is fear that adolescents have limited control over their digital technology use. The current research examines longitudinal (Study 1) and daily (Study 2) associations between U.S. adolescents' self-control and digital technological impairment and use. Using a large sample (N = 2,104; Wave 1: M[subscript age] = 12.36, 52% female, 57%…

In this article we present a new method for estimating children's total vocabulary size based on a language corpus in German. We drew a virtual sample of different lexicon sizes from a corpus and let the virtual sample "take" a vocabulary test by comparing whether the items were included in the virtual lexicons or not. This enabled us to…

This study set out to explore levels of religious affect (measured by the Francis Scale of Attitude toward Christianity) and personal affect (measured by the Oxford Happiness Questionnaire) among samples of Catholic students in the Republic of Ireland attending fifth- and sixth-year classes (N = 3015) and Catholic students in Northern Ireland…

The current study examined the unique and interactive effects of family and community violence across types of violence (weapon, physical, and death) and relationship proximity (self, family/friend, and strangers) in African American adolescents (mean age = 12.63, SD = 0.99, 54% female). Items from the community violence and family violence…
