Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.  相似文献

Previous research has documented that adverse life experiences during adolescence, particularly for ethnic minorities, have a long-term influence on income and asset attainment and that this relationship is largely mediated by educational achievement. We extend prior research by investigating three research questions. First, we investigate the extent to which community disadvantage, family factors and race/ethnicity each exert an independent influence on young adult socioeconomic attainment. Second, we examine whether youths’ educational attainment mediates these independent influences on socioeconomic attainment. Third, we test whether educational attainment ameliorates the negative influences of disadvantaged community and family conditions and race/ethnicity on socioeconomic attainment. We address these questions using multilevel modeling with longitudinal, prospective data from Waves 1 and 4 of National Longitudinal Study of Adolescent Health, which has a nationally representative sample of adolescents (N?=?13, 450; 53?% females). Regarding our first research question, our results indicated that African Americans, youth from disadvantaged communities, lower SES families achieve significantly lower levels of earnings, assets, and job quality during young adulthood. Second, we found that young adults’ educational level only partially mediate the influences of family and race/ethnicity influences on young adults’ socioeconomic attainment. Third, we found that young adults’ educational level buffered the influence of early socioeconomic adversities and accentuated the positive influences of family resources. Findings highlight the importance of social context as well as educational opportunities during childhood and adolescence for economic stability in early adulthood.  相似文献

Despite the declining rate of teen pregnancies in the United States, academic and public health experts have expressed concern over the still relatively high rate of rapid repeat pregnancies among adolescents, particularly among minority youth. Using a sample of over 300 African American female adolescents, the current study used insights from the prototype/willingness model of adolescent risk behavior to explore this risk. More specifically, it assessed the relationship between entry into unwed motherhood during mid-to-late adolescence and changes in prototypes of unmarried pregnant teens. Further, it explored the extent to which these changing prototypes accounted for young mothers’ later contraceptive expectations. We tested the possibility that social images were affected not only by personal experience (the birth of a child) but also by the family and community context in which this experience took place. The findings show that the early entrance into teen motherhood was associated with a shift toward more favorable prototypes of unwed pregnant teens, but that this was only the case for young mothers in disadvantaged contexts. Given this, prototype changes helped to explain the link between teen motherhood and contraceptive expectations only for those in disadvantaged contexts. We discuss these findings in terms of their practical and theoretical implications.  相似文献

Corporal punishment is a controversial practice used by the majority of American parents and is especially prevalent among African Americans. Research regarding its consequences has produced mixed results although it is clear that there is a need for considering the context within which corporal punishment is administered. To assess the impact of spanking, we employed an expanded parenting typology that includes corporal punishment. Longitudinal self-report data from a sample of 683 African American youth (54 % female) were utilized to evaluate the relative impact of the resulting eight parenting styles on three outcomes: conduct problems, depressive symptoms, and school engagement. Results from Negative Binomial Regression Models indicate that the effect of corporal punishment depends upon the constellation of parenting behaviors within which it is embedded and upon the type of outcome being considered. While it is never the case that there is any added benefit of adding corporal punishment, it is also the case that using corporal punishment is not always associated with poor outcomes. Overall, however, our findings show that parenting styles that include corporal punishment do not produce outcomes as positive as those associated with authoritative parenting.  相似文献

This is a study of cultural change within democratization. It uses conflict theory to understand the culture of conflict escalation and management, taking Argentina as its example. Beginning with the most extreme dictatorships, The Dirty War and the Rosas period, and then looking at other periods of governance, the essay illustrates that Argentina has an authoritarian culture of conflict. The essay suggests why these patterns have developed in Argentina. It asks whether it is possible to change such cultural patterns and whether the current democratizing effort includes efforts at change. It concludes that the democratization efforts since 1983 have included attempts to change culture, as well as electoral and institutional movement toward democracy.  相似文献

We examine the relationship between values and beliefs about economic justice by conducting a cross-cultural analysis. Social values of Americans and West Germans are compared and the relationships between values and beliefs about the fairness of the distribution of business profits are examined. Data are from the 1984 General Social Survey and its West German counterpart, the 1984 ALLBUS; both surveys contain identical value and economic justice items. We find that among citizens in both countries beliefs about the fairness of the distribution of business profits are related to values even when income and education are held constant, but the relationship is stronger in West Germany. For Americans, beliefs about the fairness of the distribution of business profits are related primarily to conservative values (beliefs that greater efforts lead to greater rewards). In addition, the positive influence of conservative values and of income level on fairness judgments is greater for Americans with higher levels of education. For West Germans, beliefs about the fairness of business profits are related both to conservative and to liberal values (beliefs that class divisions persist). In general, economic fairness judgments of West Germans have a strong ideological basis, but polarization associated with differing ideologies is found. Economic fairness judgments of Americans showed both a simpler ideological basis and some relationship to self-interest. The influence of both factors on Americans' fairness judgments seemed to be affected by socialization due to education. Results are discussed in terms of the prevailing economic ideologies in both countries.  相似文献

There simply is no dos-and-don'ts checklist that will address the myriad issues facing children's attorneys and eliminate the difficult questions that face them. Conscientious lawyering is the key to alleviating potential ethical culpability. This requires the commitment of significant time to learn about the child client and his or her special needs. Unique responses are often required to meet individual problems. Beyond that, attorneys for children are left to determine their own subjective criteria to guide their representation.1
The child is a person, not an object of concern.2  相似文献
