Predicting substance use behavior among South African adolescents: The role of leisure experiences across time.

Using seven waves of data, collected twice a year from the 8th through the 11th grades in a low-resource community in Cape Town, South Africa, we aimed to describe the developmental trends in three specific leisure experiences (leisure boredom, new leisure interests, and healthy leisure) and substance use (cigarettes, alcohol, and marijuana) behaviors and to investigate the ways in which changes in leisure experiences predict changes in substance use behaviors over time. Results indicated that adolescents’ substance use increased significantly across adolescence, but that leisure experiences remained fairly stable over time. We also found that adolescent leisure experiences predicted baseline substance use and that changes in leisure experiences predicted changes in substance use behaviors over time, with leisure boredom emerging as the most consistent and strongest predictor of alcohol, cigarette, and marijuana use. Implications for interventions that target time use and leisure experiences are discussed.

Proactive and Reactive Sibling Aggression and Adjustment in Adolescence

Existing research on aggression tends to narrowly focus on peers; less is known about sibling aggression, most likely due to its historical acceptance. Aggression is characterized by its forms (i.e., physical vs. social or relational aggression) and its functions (i.e., the motivations behind the aggressive act and categorized as proactive vs. reactive aggression). We use data from a two-wave study of middle (n = 197; Mage = 12.63 years at Wave 1) and older (n = 159; Mage = 16.50 years at Wave 1) adolescents to assess the extent to which proactive and reactive functions of sibling aggression make unique or conditional contributions to adolescent adjustment (i.e., depression, delinquency, and substance use). We find that proactive sibling aggression increases risk for problem substance use and delinquent behavior, reactive sibling aggression increases risk for depressed mood and delinquent behavior, and such results are observed even with statistical adjustments for sociodemographic and family variables, stressful life events, and prior adjustment. Few conditional effects of proactive or reactive sibling aggression by sex or grade are observed; yet, for all three outcomes, the harmful effects of reactive sibling aggression are strongest among adolescents who report low levels of proactive sibling aggression. The results speak to the importance of understanding the proactive and reactive functions of sibling aggressive behaviors for adolescent adjustment.

A Dialectical Approach to Theoretical Integration in Developmental-Contextual Identity Research.

Future advances in identity research will depend on integration across major theoretical traditions. Developmental–contextualism has established essential criteria to guide this effort, including specifying the context of identity development, its timing over the life course, and its content. This article assesses 4 major traditions of identity research—identity status, eudaimonic identity, sociocultural theory, and narrative identity—in light of these criteria, and describes the contribution of each tradition to the broader enterprise of developmental–contextual research. This article proposes dialectical integration of the 4 traditions, for the purpose of generating new questions when the tensions and contradictions among theoretical traditions are acknowledged. We provide examples from existing literature of the kinds of research that could address these questions and consider ways of addressing the validity issues involved in developmental–contextual identity research.

Practical Considerations Community Context in a Declining Rural Economy and Emerging Adults’ Educational and Occupational Aspirations

We examine how aspects of community context (i.e., social and familial attachments, attachment to place, and economic environment) are linked to rural emerging adults’ educational and occupational experiences and aspirations. We use a year of qualitative interview data and 2 years of longitudinal survey data to explore how community context may shape two groups of rural emerging adults’ aspirations for those who remain in their rural home community posthigh school graduation and those who leave after high school to seek opportunities elsewhere. We found that the declining economic context of these rural communities shaped educational and occupational aspirations of both groups toward practically focused occupations. Interviewees struggled to balance their positive community attachments with the area’s lack of occupational opportunities. Our work uniquely underscores that analysis of community context may be a key to understanding emerging adults’ educational and occupational pathways and aspirations in economically strained rural environments.

Perceived Local Job Prospects and School Connectedness in a Struggling Rural Economy: A Life-Course Perspective

Late in first decade of the 2000s, the closing of pulp and paper mills in the rural northeastern United States contributed to economic decline in the region and to rising concerns about population decline due to out-migration among local emerging adults in search of occupational or educational opportunities. In this context, and drawing on a life-course framework, the present study used four waves of panel data from the population of 7th- and 11th-grade public school students in a rural northeastern U.S. county to explore whether the county unemployment rate was related to perceived local job prospects; school connectedness was related to subsequent perceived job prospects; and the effects of county unemployment and school connectedness on perceived local job prospects varied by age cohort. Initially, changes in respondents’ perceptions about local job prospects paralleled shifts in local unemployment similarly for both cohorts; yet after the older cohort respondents had completed high school, their perceived local job prospects fell sharply, while perceptions among the younger cohort respondents, who were still in high school, remained stable. Among the older cohort respondents only, school connectedness was associated with subsequent positive perceptions about local job prospects net of relevant controls. Same-age cohort comparisons, evaluated when each cohort was in 12th-grade, showed no differences in the short-term effects of school connectedness on perceived local job prospects, despite variations in the age-linked timing of the most dramatic rise in unemployment during the study. The results highlight the lasting importance of school connectedness for teens raised in struggling rural economies.
