This preregistered, longitudinal study examined how much adolescents value and integrate their parents' and peers' attitudes into their own attitudes from early to middle adolescence. Across three waves, participants (N = 172, 91 female, 11-16 years across three waves; 439 data points) decided whether to pay money to learn their parents' or peers'…

Neighborhood social processes may have important implications for parenting processes and ethnic-racial identity (ERI) processes and content in adolescence. Past research suggests that adolescents whose parents engaged in more cultural socialization, an important aspect of parental racial socialization, had higher levels of ERI processes and…

This longitudinal ecological momentary assessment study examined whether adolescents' use of social media to interact with peers relates to their experiences of social connectedness, social craving, and sensation seeking on an hourly level. Further, we investigated whether these associations differ for adolescents who were nominated by their peers…

To advance understanding of parents' and adolescents' unique and shared perspectives of familism, a core cultural value in Mexican-origin families, our study addressed 2 goals. First, we identified family members' unique and shared perspectives of familism values using multitrait-multimethod confirmatory factor analysis (Kenny & Kashy, 1992).…

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.…

Although literature provides strong evidence for the beneficial role of outgroup contact, longitudinal knowledge regarding the formation and change of outgroup contact remains improvable. Using a longitudinal, large-scale data set including 6,726 majority and minority participants (M[subscript age] = 14.98 years at Wave 1; 55% female) from 4…

Adolescence and young adulthood are characterized by substantial sociodemographic, family, social, and personality changes that may influence loneliness. Although loneliness is a public health challenge, we know little about how loneliness develops during these periods. Our study addresses this lacuna by using 4-wave longitudinal data from 3,116…

The aim of this study was to examine trajectories of pathological video game symptoms over a 6-year period from adolescence to emerging adulthood. We also examined a number of predictors and outcomes for different trajectories. Participants included 385 adolescents (M age = 15.01 at the initial time point) who completed multiple questionnaires…

In the present study, we examined changes in identity dynamics during adolescence using the Dimensions of Identity Development Scale (DIDS), focusing on social and cultural factors possibly affecting identity formation. Identity formation among adolescents outside Western countries is largely unexplored; therefore, we focused on adolescents in…

Achievement goal theory has long been a dominant model in the study of student motivation. However, a relatively small number of researchers have investigated gender differences in achievement goals or have considered the possible role that social and extrinsic goals may play in student academic motivation. Adopting a person-centered multiple…

This study aimed to investigate prospective predictors and health-related outcomes of positive body image in adolescent girls. In so doing, the modified acceptance model of intuitive eating was also examined longitudinally. A sample of 298 girls aged 12 to 16 years completed a questionnaire containing measures of body appreciation, potential…

During adolescence, gender identity (GI) develops through a dialectic process of personal reflection and with input from the social environment. Peers play an important role in the socialization of gendered behavior, but no studies to-date have assessed peer influences on GI. Thus, the goal of the present study was to examine peer influences on…

Adolescence is a vulnerable period for the initiation and peak of many harmful risk-taking behaviors such as smoking, which is among the most addictive and deadliest behaviors. Generic metatheories like the theory of triadic influence (TTI) suggest that interrelated risk factors across multiple domains (i.e., intrapersonal and…

The current study examined longitudinal cross-lagged associations between prosocial TV (content and time) and prosocial and aggressive behavior during adolescence, and explored the mediating role of empathic concern and self-regulation. Participants were 441 adolescents who reported on their 3 favorite TV shows at 2 time points, approximately 2…

Co-rumination is a dyadic process between relationship partners that refers to excessively discussing problems, rehashing problems, speculating about problems, mutual encouragement of problem talk, and dwelling on negative affect. Although studies have addressed youths' "tendency" to co-ruminate, little is known about the nature of…
