Scientific research has made major contributions to adolescent health by providing insights into factors that influence it and by defining ways to improve it. However, US adolescent sexual and reproductive health policies—particularly sexuality health education policies and programs—have not benefited from the full scope of scientific understanding. From 1998 to 2009, federal funding for sexuality education focused almost exclusively on ineffective and scientifically inaccurate abstinence-only-until-marriage (AOUM) programs. Since 2010, the largest source of federal funding for sexual health education has been the “tier 1” funding of the Office of Adolescent Health’s Teen Pregnancy Prevention Initiative. To be eligible for such funds, public and private entities must choose from a list of 35 programs that have been designated as “evidence-based” interventions (EBIs), determined based on their effectiveness at preventing teen pregnancies, reducing sexually transmitted infections, or reducing rates of sexual risk behaviors (i.e., sexual activity, contraceptive use, or number of partners). Although the transition from primarily AOUM to EBI is important progress, this definition of evidence is narrow and ignores factors known to play key roles in adolescent sexual and reproductive health. Important bodies of evidence are not treated as part of the essential evidence base, including research on lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth; gender; and economic inequalities and health. These bodies of evidence underscore the need for sexual health education to approach adolescent sexuality holistically, to be inclusive of all youth, and to address and mitigate the impact of structural inequities. We provide recommendations to improve US sexual health education and to strengthen the translation of science into programs and policy.  相似文献

Understanding psychosocial factors that affect the academic achievement of Hispanic adolescents remains a nationwide priority in the United States. Extending previous studies of the stressful effects of perceived discrimination, this year-long longitudinal study examined the correlates of perceived ethnic in-group rejection, coping strategies and fatalistic beliefs, on depressive symptoms, grades, and college aspirations of 2,214 Hispanic adolescents (54 % female) in Southern California. Based on the transactional model of stress and coping and on self-perception theory, structural equation models revealed that high perceived intragroup rejection (10th grade) and low levels of active coping (11th grade) were associated with depressive symptoms in 11th grade. Also, depressive symptoms partially mediated the link between intragroup rejection and both academic outcomes. Avoidant coping strategies (e.g., watching TV) also predicted depressive symptoms and were positively related to fatalism. In addition, fatalism was negatively related to grades and aspiration to attend college. The findings suggest the need to help adolescents find adequate outlets for communication and to create awareness about the potential effects of intragroup rejection.  相似文献

Conventional wisdom and scholarly research indicate that to win a policy debate political actors should frame the issue strategically—that is, selectively highlight considerations that mobilize public opinion behind their policy position. Engaging the opponent in a dialogue (i.e., focusing on the same considerations) is portrayed as a suboptimal strategy because political actors forfeit the ability to structure the debate. Using over 40 public opinion polls and a detailed content analysis of news stories, I examine the use of framing and engagement strategies during the 1993–94 debate over health care reform. The analysis shows that engagement was more effective at increasing support for reform than framing. This study is the first to document the role of engagement in a policy debate, and it extends work showing that this strategy is more common in election campaigns than scholars once suspected.

Achievement, engagement, and students’ quality of experience were compared by racial and ethnic group in a sample of students (N = 586) drawn from 13 high schools with diverse ethnic and socioeconomic student populations. Using the Experience Sampling Method (ESM), 3,529 samples of classroom experiences were analyzed along with self-reported grades. Similarities and differences in achievement, engagement, and quality of experience among white, black, Latino, and Asian students were examined. The most marked differences found were between black and white students. Consistent with several previous studies, an engagement–achievement paradox was found in which black students reported higher engagement, intrinsic motivation, and affect in classrooms, but lower GPA relative to white students. A similar engagement–achievement paradox was found for students from low SES communities compared to those from high SES communities. Analyses also revealed racial and ethnic differences in the relationship of engagement with on-task behavior and contextual factors. Being on-task when in classrooms had a more positive effect on the engagement of black students relative to white students. The contextual effect of being in school versus home or in public on engagement was also more positive for black students than white students. Contextual factors and measurement issues are emphasized in the interpretation of findings and suggestions for future research.

David J. Shernoff   is an Assistant Professor of educational psychology at Northern Illinois University broadly interested the relationship between human development and education. He completed his doctoral studies at the University of Chicago and the Sloan Center for Working Families, where he applied Mihaly Csikszentmihalyi's theory of flow and Experience Sampling Method (ESM) to the study of engaging educational contexts. From 2000 to 2003, he served as a post-doctoral fellow at the University of Wisconsin, Madison. His recent publications include “Engagement in after-school program activities: Quality of experience from the perspective of participants” in Journal of Youth and Adolescence (Shernoff and Vandell 2007). Jennifer A. Schmidt   is Associate Professor of Educational Psychology at Northern Illinois University. Her research focuses on the nexus of subjective experience, context, and individual development by examining the ways in which social, cultural, and situational circumstances mold experience, which in turn affects development. She earned her PhD. in Psychology: Human Development from the University of Chicago in 1998, where she studied how adolescents’ daily experiences with challenge fosters resilience among adolescents facing adversity. Following the completion of her doctoral studies she was appointed Research Director for the University of Chicago’s Sloan Center on Parents, Children and Work, housed within the National Opinion Research Center. In 2001 she joined the faculty at NIU, where she teaches courses in Educational Psychology and Child Development, Research Design, and Motivation.  相似文献

The involvement of adolescents with deviant peer groups is one of the strongest proximal correlates to juvenile delinquency and stems from a variety of causes. Past research has linked ineffective parenting with peer variables, including deviant peer group involvement and peer conflict during adolescence. In this study, adolescents’ appraisals of procedural justice within the family (adolescents’ appraisals of how fairly they are treated by parents in the process of resolving family conflict) were examined as one aspect of effective parenting that may relate to deviant peer group involvement in early adolescence. Data from 1660 middle school students (ages 11–14, mean = 12.6) indicated that higher appraisals by adolescents of procedural justice during family conflict resolution were related to lower levels of both peer conflict and deviant peer group involvement. A structural model was tested in which the relationship between adolescents’ appraisals of procedural justice in the family and deviant peer group involvement was partially mediated by measures of peer conflict. This model was found to have adequate fit to the data, indicating that part of the relationship between procedural justice appraisals and deviant peer group involvement can be explained by levels of peer conflict. Implications of these findings are discussed.

The current study, using data from 374 African American students (59.4% female) in grades 7–12 attending a rural, southern county public school, addressed associations of self-efficacy, ethnic identity and parental support with “future education orientation.” Both gender and current level of achievement distinguished adolescents with differing levels of future education orientation. The strongest predictors of future education orientation were self-efficacy, ethnic identity and maternal support. Gender did not moderate these associations. Implications for future research include the need to conduct longitudinal studies and research that integrates quantitative and qualitative methods to elucidate further the nature and importance of future education orientation for African American youth. Also needed are policies and programs that facilitate school bonding and academic performance, as are efforts that focus specifically on enhancing the future education orientation and academic success of African American male adolescents.

This study examines whether parents have the prerequisite knowledge about police interrogation that would allow them to compensate for youths’ knowledge deficits, protect their interests, and buffer against their vulnerability to coercion. A racially diverse urban/suburban convenience sample of 77 11- to 13-year-olds, 46 14- to 15-year-olds, and 47 16- to 17-year-olds and their parents completed a semi-structured interview on knowledge of legal rights and police practices. Results show that parents know more than younger adolescents about components of the Miranda warning and its behavioral implications but do not necessarily know more about police strategy or the parameters of parental protection. Age and socioeconomic status were associated with youths’ risk for poor knowledge. Among parents, IQ, race, and the child’s age predicted risk classification. Parent IQ, socioeconomic status, and youths’ justice experience, race, and age predicted whether families were classified as at risk for poor knowledge. The results question legal assumptions about parents’ capacity for protecting youths’ interests without intervention.

This article discusses women and peace-building in Solomon Islands and the effect of law, theory and practical circumstances on their role. It looks at the place of Solomon Islands women in society historically, with particular reference to war and peace. It then analyses their current status from a legal perspective, looking at the existing Constitution, the proposed Federal Constitution, and relevant aspects of international law. It questions whether gender equity provisions are sufficient to promote participation at a practical level. The article also disputes the effectiveness of various international, regional, and local initiatives, designed to enhance the status of women. The article discusses the application of some of the theories relating to women and peace-building to the circumstances of Solomon Islands. It concludes by looking to the future and discussing means of consolidating women’s position, and increasing their involvement in leadership and decision-making.
