A longitudinal examination of breadth and intensity of youth activity involvement and successful development.

Connections between youth activity involvement and indicators of successful development were examined in a longitudinal high school sample. Drawing on theories of expertise skill development (e.g., J. Côté, 1999); the selection, optimization, and compensation framework (P. B. Baltes, 1997); and theories of positive youth development (e.g., R. M. Lerner, J. B. Almerigi, C. Theokas, & J. Lerner, 2005), reciprocal associations between breadth and intensity of activity involvement and developmental success were explored. Time 1 breadth (but not intensity) and increases in breadth predicted higher levels of successful development at Time 2 (20 months later). Time 1 developmental success and improvements predicted greater Time 2 breadth and intensity. Implications for research and theory related to connections between youth activity involvement and successful development are discussed.

Where Is the Syndrome? Examining Co-Occurrence Among Multiple Problem Behaviors in Adolescence

The authors examined co-occurrence among a wide range of adolescent problem behaviors: alcohol, smoking, marijuana, hard drugs, sexual activity, major and minor delinquency, direct and indirect aggression, and gambling. Using a large self-report survey of high school students, confirmatory factor analysis was used to test the problem syndrome model proposed by problem behavior theory. A 3-factor model provided better overall fit than did a single problem syndrome factor model. Contingency table analyses were used to examine the co-occurrence of problem behaviors at different levels of involvement within individuals, as well as relative risk ratios. Analyses offered modest support for a limited problem syndrome encompassing the report of high-risk involvement with alcohol, minor delinquency, direct aggression, and, to a lesser extent, marijuana. For each problem behavior, the majority of adolescents did not report high-risk involvement, and only a minority reported any involvement with multiple behaviors.

On the Association between Sexual Attraction and Adolescent Risk Behavior Involvement: Examining Mediation and Moderation.

On the basis of a large-scale survey of high-school youth, the authors compared adolescents reporting exclusively heterosexual, mostly heterosexual, bisexual, and predominately same-sex attraction based on high-risk involvement across a range of risk behaviors. Bisexual and same-sex attracted groups were characterized by heightened high-risk involvement relative to the other two groups. Mediation analysis was used to determine whether these group disparities were explained by a set of normative predictive factors spanning multiple life domains. Differences among a combined exclusively/mostly heterosexual attraction group and both the bisexual and same-sex attraction groups were attenuated (66% and 50%, respectively) after incorporating the hypothesized intervening predictive factors, providing evidence of partial mediation. Primary mediators included intrapersonal (attitudes toward risk-taking; academic orientation), interpersonal (peer victimization; parental relationships; unstructured activities), and environmental (substance availability) factors. Mediation results were consistent across participant age and sex. Implications, limitations, and directions for future research are discussed.

Do predictors of gambling involvement differ across male and female adolescents

We examined gender-specific factors, which might be related to adolescent gambling behavior, using a comprehensive set of predictors from neighborhood, school, family, peer, and intrapersonal domains. Discriminate function analyses revealed a unique pattern of results for each gender. The noteworthy predictors for males were similar to what is found to be predictors of other risk behaviors, suggesting that there may be a similar etiology to gambling participation as found with other risk behaviors. Compared to males, the model for females suggests that parents and peers may have a greater influence on engagement in gambling behavior. Participation in unstructured activities, and risk attitudes/perceptions were the only consistent noteworthy predictors across both males and females. Implications are discussed.

Adolescent peer interaction and trait surgency weaken medial prefrontal cortex responses to failure

Adolescent risk taking has been known to increase in the presence of peers. We hypothesized that peer interaction reduces the activation of the medial prefrontal cortex (mPFC) that is required for self-regulation of reward-driven behavior. We also expected that mPFC activity would be reduced more in those with greater surgency, a composite trait of behavioral approach, sensation seeking and positive affect. In our study, 20 15-year-old boys played a simulated driving video game alone and in the presence of peers who were encouraged to call out advice while we recorded the feedback-related negativity (FRN) event-related potential in response to an impending car crash. FRN amplitude was reduced both as a function of peer presence and increased surgency. More importantly, we also calculated intracerebral current source density at the time of the FRNs, and found that both greater surgency and peer presence are associated with reduced activity specifically in the mPFC. Riskier performance resulting in more car crashes resulted from the presence of peers only as an interaction with surgency, this interaction being related strongly to reduced activity in the ventromedial PFC.

Adolescent Non-Involvement in Multiple Risk Behaviors: An Indicator of Successful Development?

Based on the conceptualization of successful development as the joint maximization of desirable outcomes and minimization of undesirable outcomes (Baltes, 1997), the present study examined connections between adolescent non-involvement in multiple risk behaviors and positive developmental status. Results from a survey of 7290 high school students were used to define four profiles of risk behavior involvement (complete non-involvement, some involvement, some high-risk involvement, predominantly high-risk involvement) based on self-reported involvement in nine risk behaviors (alcohol, smoking, marijuana, hard drugs, sexual activity, minor and major delinquency, direct and indirect aggression). Groups were compared across intrapersonal (risk behavior attitudes, temperament, well-being, religiosity, academic orientation), interpersonal (parental relations, parental monitoring, friendship quality, victimization, unstructured activities), and environmental (school climate, neighborhood conditions) domains. Despite some similarities between the complete non-involvement and some involvement groups, the complete non-involvement group had the most positive self-reports compared to each of the other groups in each developmental domain. At the same time, higher levels of positive development were not exclusive to the complete non-involvement group. Implications for research and theory related to connections between adolescent non-involvement in risk behaviors and successful development are discussed.

A Rationale and Method for Examining Reasons for Linkages Among Adolescent Risk Behaviors

A large volume of research has investigated interrelations among adolescent risk behaviors. Although several theoretical accounts have been proposed, researchers have not directly examined hypotheses for why risk behaviors are linked. In the present paper, a distinction is drawn between predictive factors that explain variance in risk behaviors and “linkage factors” which may provide an explanation for why risk behaviors are interrelated. The relevance of linkage factors to risk behavior research, theory, and practice is described. Further, a simple to use and easy to interpret analytic technique for exploring linkage-related issues is illustrated. Using this technique, hypotheses regarding the role of predictors in explaining linkages among risk behaviors can be tested directly. The proposed line of inquiry will provide valuable input for intervention efforts and theoretically relevant information concerning linkages among adolescent risk behaviors.
