The present 8-year longitudinal study examined how multiple aspects of family relationships change across the transition from adolescence (M[subscript age] = 15 years) to young adulthood (M[subscript age] = 22 years) among 821 individuals. Results showed that there was more discontinuity than continuity in family relationships across this…

This longitudinal study examined how nightly variations in adolescents' study and sleep time are associated with academic problems on the following day. Participants ("N" = 535, 9th grade M[subscript age] = 14.88) completed daily diaries every day for 14 days in 9th, 10th, and 12th grades. Results suggest that regardless of how much a…

Changes in adolescents' ethnic identity (e.g., exploration, belonging) were examined over the 4 years of high school. Results from 541 adolescents (51% female) with Latin American, Asian, and European backgrounds suggest that, as a group, adolescents do not report developmental changes in their ethnic exploration and belonging over time. Yet,…

Using a daily diary method, this study assessed daily episodes of family and peer conflict among 578 adolescents in the 9th grade to examine potential bidirectional associations between the family and peer domains. Adolescents completed a daily diary checklist at the end of each day over a 14-day period to report events of conflict and their…

Parent-adolescent conflict appears to be similar across different immigrant generations and cultural groups in frequency and implications for adjustment. However, the same level of argumentation may mask hidden conflictual feelings that are not expressed. Why an acculturation gap leads to such conflictual feelings in some adolescents and not…

Establishing a sense of life meaning is a primary facet of well-being, yet is understudied in adolescent development. Using data from 579 adolescents (53% female) from Latin American, Asian, and European backgrounds, demographic differences in meaning in life, links with psychological and academic adjustment, and the role of meaning in explaining…

Understanding adolescents' use of ethnic labels is a key developmental issue, particularly given the practical significance of identity and self-definition in adolescents' lives. Ethnic labeling was examined among adolescents in the traditional immigrant receiving area of Los Angeles (Asian n = 258, Latino n = 279) and the non-traditional…

Family obligation is an important aspect of family relationships among families from Mexican backgrounds and can have significant implications for adolescents' well-being. Prior research and theory regarding youths' obligations offer conflicting hypotheses about whether it is detrimental or beneficial for adolescents' well-being. In the current…

The authors tested the evolutionary genetic hypothesis that the functional form of an asymmetrically risky Gene x Environment interaction will differ as a function of age-related antagonistic pleiotropy (i.e., show opposite effects in young vs. old individuals). Previous studies have identified a polymorphism in the human "IL6" promoter…

Previous research addressing the dynamics of stigma and academics has focused on African American adolescents and adults. The present study examined stigma awareness, academic anxiety, and intrinsic motivation among 451 young (ages 6-11) and diverse (African American, Chinese, Dominican, Russian, and European American) students. Results indicated…

Much of the research on adolescent friendships and school achievement has focused on in-school friends, ignoring the potential effects of having out-of-school friendships. The goal of this study was to examine the relation between having relatively more in-school friends and school achievement among a sample of over 600 12th grade students from…

The daily diary method was used to examine the implications of adolescents' daily assistance behaviors for both positive and negative aspects of psychological well-being among an ethnically diverse sample of 752 adolescents of ages 14 to 15 years. Results indicated that, contrary to the expectations of some observers, providing daily assistance to…

The influence of immigrant-background adolescents' heritage language (HL) proficiency and use of the language on parent-adolescent relationships and ethnic identity was investigated in a sample of 414 adolescents from Latin American and Asian backgrounds. HL proficiency, but not language use, was positively associated with the quality of…

A longitudinal daily diary method was employed to examine the implications of family assistance for the academic achievement of 563 adolescents (53% female) from Mexican (n = 217), Chinese (n = 206), and European (n = 140) backgrounds during the high school years (mean age 14.9 years in 9th grade to 17.8 years in 12th grade). Although changes in…

Ninth graders (N = 679; 50% male, 50% female) from Latin American (41%), Asian (38%), and European (21%) backgrounds reported on their ethnic identity and family attitudes and relationships. Adolescents also completed daily checklists of family interactions over a two-week period. Results indicated that ethnic identity, measured through…
