The current study extended limited prior work on polysubstance use among youth in the child welfare system (CWS) by addressing their potentially greater risk of engaging in polysubstance use, the causes of interpersonal variation in use, and changes in use over time, particularly at later points of involvement in the CWS. Using longitudinal data from the National Survey of Child and Adolescent Well-Being (n = 1,178), a series of time-invariant and time-varying demographic and contextual factors were explored to assess their role both overall and at unique points of involvement in the CWS. A series of unconditional and conditional curve-of-factor models were estimated and results indicated that time-invariant characteristics of ethnicity and gender were not related to polysubstance use. Time-variant characteristics of age and placement were associated with polysubstance use and highlighted the dynamic nature of age as a risk factor. Out-of-home placement was protective against later substance use for youth who had been removed from contexts with their original caretaker where there were higher levels of reported violence. Our results suggest that in the child welfare population, the modeling of multiple substances rather than a single substance in isolation is more informative because it yields information on the confluence of behaviors that tend to occur and evolve together. 相似文献

In a Registered Report, the authors propose a new survey-bias-mitigation method—incorporating inverse probability weighting via boosted regression—to better understand lesbian, gay, bisexual, or questioning (LGBQ)-heterosexual youth risk disparities. This method is tested using the 2019 US Centers for Disease Control and Prevention-collected Youth Risk Behavior Survey (YRBS) national data, which contain 12,847 observations (ages 12–18 [M = 16, SD = 1.25]; 49.1% male [8.7% LGBQ] and 50.9% female [22.4% LGBQ]; nationally representative regarding race and ethnicity). Looking across 44 outcomes, the authors found that the YRBS contains responses that are potentially biased against LGBQ youth in systematic ways, inflating perceived risk for this group in some outcomes. This potential bias is more pronounced among reported males than among reported females, and it is more pronounced for low-incidence outcomes. For example, the steroid-use disparity estimate among reported males reduced by 67%, while the reduction in bullying victimization was small and not statistically significant. The authors discuss robustness of results, the new method, and data policy implications. 相似文献

Education for All has focused international attention on the goals of universal primary education and improved education quality.
However, national indicators related to these goals often mask significant differences among demographic and social groups,
as well as among geographical regions within countries. This paper, based on a study commissioned by UNESCO’s Global Monitoring
Report team, examines within-country (regional) disparities in participation in primary education in between 55 and 60 countries
in sub-Saharan Africa, Asia and the Pacific, Latin America and the Arab States. After reviewing the methodology used in the
analysis, the paper compares countries’ disparities in net enrolment rates before and after the Dakar Framework was established
in 2000, changes over the pre- to post-Dakar period and a comparison of net enrolment rates with pupil-teacher ratios—one
of the standard measures of education quality. Overall, the analysis finds significant differences in the magnitude of regional
disparities in primary participation across the countries, with the smallest disparities in Latin America and the largest
in sub-Saharan Africa. While just over half the countries with both pre- and post-Dakar data showed improvements over the
period, there was little change in countries’ rankings on the disparities measures over this period. 相似文献

Little is understood about why some youth from low‐socioeconomic‐status (SES) environments exhibit good health despite adversity. This study tested whether role models and “shift‐and‐persist” approaches (reframing stressors more benignly while persisting with future optimism) protect low‐SES youth from cardiovascular risk. A total of 163 youth, ages 13–16, completed role model interviews and shift‐and‐persist measures while cholesterol and inflammatory markers, interleukin‐6 (IL‐6), and C‐reactive protein were assessed. Low‐SES youth with supportive role models had lower IL‐6. Low‐SES youth high in shift‐and‐persist also had lower IL‐6. Shift‐and‐persist partially mediated the interaction of SES and role models on IL‐6. Benefits were not found among high‐SES youth. Identifying psychological buffers in low‐SES youth has implications for health disparities. 相似文献

Mental health disparities between heterosexual and sexual minority youth are partly explained by the higher rates of victimization experienced by sexual minority youth. The onset and progression of these victimization disparities, however, are poorly understood. Using multirater longitudinal data, trajectories of victimization starting at age 9 were compared among youth who did and did not report same-sex attraction at age 15 (N = 310). Self and teacher, but not primary caregivers, reported victimization was significantly higher among sexual minority youth starting at age 9, but did not vary across time. The findings underscore the importance of understanding homophobic experiences of sexual minority youth during late childhood and early adolescence in order to inform prevention programs. 相似文献

中国地区间收入差距问题的模型分析 总被引：2，自引：0，他引：2
从统计数据看,中国各地区间收入存在较大差距。这个问题可以通过设计一个关于地区间收入差距的模型来解释。在这个模型中,我们假设有两个地区,这两个地区只有一个行业,并假设资本不能进行地区间的相互流动,从而表示出两个地区间的人均收入差距。于是就有了地区间人均收入差距形成的原因及消除地区间收入差距的条件。分析结果表明:地区间的禀赋差距和劳动力缺乏流动是中国地区间收入差距产生的主要原因;政府的转移支付和劳动力的自由流动,对消除地区间的收入差距有着十分重要的意义。 相似文献

This study examined the impact of the Family Check-Up (FCU) and linked intervention services on reducing health-risk behaviors and promoting social adaptation among middle school youth. A total of 593 students and their families were randomly assigned to receive either the intervention or middle school services as usual. Forty-two percent of intervention families engaged in the service and received the FCU. Using complier average causal effect analyses, engagement in the intervention moderated intervention outcomes. Families who engaged in the intervention had youth who reported lower rates of antisocial behavior and substance use over time than did a matched control sample. Results extend previous research indicating that a family-centered approach to supporting youth in the public school setting reduced the growth of antisocial behavior, alcohol use, tobacco use, and marijuana use throughout the middle school years. 相似文献

Using data from the National Education Longitudinal Study of 1988, this study documented college attendance patterns of rural youth in terms of the selectivity of first postsecondary institution of attendance, the timing of transition to postsecondary education, and the continuity of enrollment. The study also examined how these college attendance patterns among rural students differed from those among their nonrural counterparts and which factors explained these rural–nonrural differences. Results showed that rural youth were less likely than their nonrural counterparts to attend a selective institution. In addition, rural youth were more likely to delay entry to postsecondary education compared to their urban counterparts. Finally, rural students were less likely than their urban counterparts to be continuously enrolled in college. Much of these rural–nonrural disparities in college attendance patterns were explained by rural–nonrural differences in socioeconomic status and high school preparation. Policy implications, limitations of the study, and future research directions are also discussed. 相似文献

Absctract. This article describes a two‐year study addressing the effectiveness of a highly structured, systematic tutoring intervention implemented by minimally trained college students with two cohorts of at‐risk first‐grade readers. Participants were 61 first‐grade children in Cohort 1 and 76 first‐grade children in Cohort 2. Tutors participated in three one‐hour training sessions and received occasional on‐site assistance. Individual tutoring sessions were scheduled for three to four times each week for one school year, with each cohort receiving approximately 10–14 hours of instruction across 44 sessions. The curriculum included a game to teach phonemic awareness and letter‐sound correspondence, structured word‐study activities, reading of leveled books, and simple comprehension strategies. Significant differences were found on measures of phonemic awareness and nonsense word reading for both cohorts. For Cohort 1, but not Cohort 2, significant differences were also detected for real‐word identification. Our results support using tutors to provide additional assistance and instruction in early reading, even when tutors are not professionally trained teachers. 相似文献

从主体功能区的视角对广东省公共卫生支出及公共卫生资源配置状况进行分析,结果发现,虽然近年来各类主体功能区在公共卫生支出上的差异有所缩小,但是公共卫生服务资源非均等化程度却有恶化的趋势,重点开发区和生态发展区在公共卫生资源分配中明显处于弱势地位。为了促进实现公共卫生服务均等化,必须逐步缩小重点开发区、生态发展区与优化开发区在公共卫生服务上的差距,提高公共卫生资源配置的公平性。 相似文献

ABSTRACTAt-risk adolescents may experience Social Determinants of Health (SDoH) that lead to higher rates of risky sexual behavior, including increased risk of pregnancy and sexually transmitted infections. These SDoH may include components such as unstable family structures, incomplete education, and poverty. Targeting at-risk youth for sexuality education is one way to work toward decreasing sexual health disparities. However, preferences for sexuality education approaches may differ among at-risk youth by additional factors including sex and sexual orientation. The purpose of this study was to describe sexuality education preferences among at-risk youth and how sexuality education preferences differ based on sex and sexual orientation in an at-risk sample of high school-aged youth in Texas. Results indicate sexuality education preferences differ based on sex and sexual orientation when examined by sexual health topics and methods of delivery. Implications of this study indicate including at-risk youth in sexual health programs may be a way to target those at-risk of adverse SDoH, but these groups also have specific preferences for sexuality education. 相似文献

Out-of-school-time programs for youth that are focused on STEM content are often seen as affording opportunities to increase youth engagement, interest, and knowledge in STEM domains, yet we know relatively little about how youth actually experience such programs. In this article, we explore how experiences and activities employed in the delivery of summer STEM programs are associated with youth engagement during programming, and whether youth characteristics moderate these relationships. Data were collected from 203 youth (ages 10–16) in nine summer programs using multiple methods including video, experience sampling, and surveys. Through the use of cross-classified, multi-level models, we found that youth reported higher engagement in program activities they perceived to be more challenging and relevant, and in activities, they perceived to have more affordances for learning or developing skills. Gender moderated these relationships such that the positive relationships observed among males were muted or nonexistent for girls. We further identify that program activities are differently associated with fostering challenge, relevance, and learning. Findings have implications for out-of-school STEM programming for youth. 相似文献

The purpose of this study was to examine slopes from curriculum-based measures of writing (CBM-W) as indicators of growth in writing. Responses to story prompts administered for 5 min to 89 students in Grades 2–5 were collected across 12 weeks and scored for correct word sequences (CWS) and correct minus incorrect sequences (CIWS). Linear mixed modeling revealed that, for students in Grades 2–3, a linear model with random effects on both intercept and slope fit the data best. For students in Grades 4–5, growth trends varied depending on number of weeks and scoring procedure used. The time point at which slopes were significantly different from zero varied by scoring procedure and grade. Gender was related to intercept and slope for CWS and CIWS in Grades 2–3 and to intercept and linear slope for CWS and CIWS in Grades 4–5. Findings suggest that CBM-W may be appropriate for monitoring student progress, and that gender should be considered in data-based decision making. 相似文献

The relative age effect (RAE) has been demonstrated in many youth and professional sports. In this study, we hypothesized that there would also be a RAE among youth chess players who are typically involved in a complex cognitive task without significant physical requirements. While typical RAEs have been observed in adult chess players, in this paper we wanted to focus primarily on youth chess players. In addition, we also examined RAEs in both participation rates and performance levels in a national chess championship. Therefore, the RAE was examined in a complex cognitive task that has no significant physical requirements, more specifically among youth chess players. Data were analyzed (1) for all registered Belgian youth chess players over a 5-year period (2009–2013) and (2) for participants of the Belgian youth championship 2013. Results indicated an overall RAE among all Belgian youth chess players over the last 5 years. The likelihood of participation was significantly greater for players born in the first birth-date quartile (χ² = 10.21, p < .05; r = ?.77, p < .01; w = .07) and the likelihood of participation decreased when youth chess players were born in the last quartile of the year. These effects were most prominent in the under-8 and under-10 year olds. There also appeared to be a performance-related RAE. Kolmogorov–Smirnov tests (p < .05) showed that players born in the first months of the selection year were significantly more often in the top 10 players for each age level of the Belgian Youth Championship 2013. 相似文献

Racial disparities in school discipline may have collateral consequences on the larger non-suspended student population. The present study leveraged two longitudinal datasets with 1201 non-suspended adolescents (48% Black, 52% White; 55% females, 45% males; Mage: 12–13) enrolled in 84 classrooms in an urban mid-Atlantic city of the United States during the 2016–2017 and 2017–2018 academic years. Classmates' minor infraction suspensions predicted greater next year's defiant infractions among non-suspended Black adolescents, and this longitudinal relation was worse for Black youth enrolled in predominantly Black classrooms. For White youth, classmates' minor infraction suspensions predicted greater defiant infractions specifically when they were enrolled in predominantly non-White classrooms. Racial inequities in school discipline may have repercussions that disadvantage all adolescents regardless of race. 相似文献

Although critiqued for circular reasoning and lack of definitional and analytic clarity, social capital has garnered widespread interest in two areas relevant to environmental education (EE): the impact of family and community-level social capital on positive youth development and of community-level social capital in fostering collective action to manage natural resources. Although EE is normally considered for its value relative to environmental outcomes or natural capital, intergenerational, community, and other approaches to EE may also foster social capital. Drawing on Putnam’s definition of social capital, which emphasizes civic engagement, we developed and tested for reliability a survey to measure cognitive and structural attributes of social capital among youth. We conclude that although several attributes of our instrument are useful for use with youth aged 10–18 years in EE contexts, much more work needs to be done on conceptualizing and developing measures of social capital that are relevant to EE. Further, we suggest that social capital presents a framework for how EE programs can bring youth and adults together to create the conditions that enable collective action, as a complement to ongoing work in EE focusing on individual behaviors. 相似文献

Identifying mechanisms that explain the relationship between anxiety and depression are needed. The Tripartite Model is one model that has been proposed to help explain the association between these two problems, positing a shared component called negative affect. The objective of the present study was to examine the role of loneliness in relation to anxiety and depression. A total of 10,891 school‐based youth (Grades 2–12) and 254 clinical children and adolescents receiving residential treatment (Grades 2–12) completed measures of loneliness, anxiety, depression, and negative affect. The relationships among loneliness, anxiety, depression, and negative affect were examined, including whether loneliness was a significant intervening variable. Various mediational tests converged showing that loneliness was a significant mediator in the relationship between anxiety and depression. This effect was found across children (Grades 2–6) and adolescent (Grades 7–12) school‐based youth. In the clinical sample, loneliness was found to be a significant mediator between anxiety and depression, even after introducing negative affect based on the Tripartite Model. Results supported loneliness as a significant risk factor in youths' lives that may result from anxiety and place youth at risk for subsequent depression. Implications related to intervention and prevention in school settings are also discussed. 相似文献

Truancy is known to: Hamper academic achievement, predict a range of school-related problems and cause early school leaving. Hence, the development and implementation of measures to tackle truancy are considered as important strategies to prevent early school leaving in Europe. Despite this, there is almost no comparative research which studies variation in truancy rates. This article relies on PISA 2012 data from 24 European countries to empirically answer two questions: (1) To what degree do truancy rates vary cross-nationally? and (2) Do these differences in truancy rates relate to characteristics of the educational system? We found that between-country truancy rates varied more than differences in early school leaving. Moreover, even after taking into account control variables such as economic development and youth unemployment rates, the ways in which educational systems select and group pupils are closely related to truancy rates. 相似文献
