Objective:
"What do you want to be when you grow up?" is a simple, commonly asked question that might provide insight into adolescent well-being. Career aspirations might reflect an adolescent's sense of identity, hope for the future, and self-efficacy, all of which are critical to identifying at-risk youth and intervening on risky behaviors. Howe...
Objective:
Studies suggest adolescent substance use aligns with academic and behavioral self-concept (whether teens think of themselves as good or bad students and as rule followers or rule breakers) as well as peer and adult social networks. Schools are an important context in which self-concept and social networks develop, but it remains unclear...
Background and objectives:
Despite the widespread epidemic of mass incarceration in the US, relatively little literature exists examining the longitudinal relationship between youth incarceration and adult health outcomes. We sought to quantify the association of youth incarceration with subsequent adult health outcomes.

Background:
Poor academic (eg, "I am a bad student") and behavioral (eg, "I am a troublemaker") self-concepts are strongly linked to adolescent substance use. Social networks likely influence self-concept. However, little is understood about the role teachers and athletic coaches play in shaping both academic and behavioral self-concepts.
Methods...
Background and objectives:
Current recommendations emphasize developmental screening and surveillance to identify developmental delays (DDs) for referral to early intervention (EI) services. Many young children without DDs, however, are at high risk for poor developmental and behavioral outcomes by school entry but are ineligible for EI. We develo...
Objectives:
Up to 20 % of school-age children have a vision problem identifiable by screening, over 80 % of which can be corrected with glasses. While vision problems are associated with poor school performance, few studies describe whether and how corrective lenses affect academic achievement and health. Further, there are virtually no studies ex...
Objective:
Individual academic achievement is a well-known predictor of adult health, and addressing education inequities may be critical to reducing health disparities. Disparities in school quality are well documented. However, we lack nationally representative studies evaluating the impact of school quality on adult health. We aim to determine...
Purpose:
Grit, defined as "working strenuously toward challenges, maintaining effort and interest over years despite failure, adversity, and plateaus in progress," is strongly associated with academic achievement and life success and may also be associated with health outcomes and behaviors. We examined predictors of grit, and the association betw...
Introduction:
Studies suggest students who are substantially older than the average age for their grade engage in risky health behaviors, including substance use. However, most studies do not account for the distinct reasons why students are old for their grade (ie, grade retention vs delayed school entry) or for their pubertal stage. Thus, whethe...
At-school substance use is associated with increased rates of violence and delinquency. However, whether at-school substance use is a useful marker for other serious health risks and whether this association varies by gender or substance is still unclear.
