Foster care provides round-the-clock substitute care for nearly 700,000 U.S. children who are temporarily or permanently separated from their family of origin each year. Each state manages its own foster care system according to federal regulations. Despite numerous large-scale federal policy reforms over the past several decades, substantial concerns remain about the experiences and outcomes of children in the foster care system. The most recent effort to reform foster care, the Family First Prevention Services Act of 2018, attempts to both reduce the use of foster care and increase the quality of care. In this report, we review how policy has shaped the experiences and outcomes of children in foster care, where policy has succeeded, and where it falls short of achieving its goals. We then identify opportunities for federal and state policy to better support the safety, health, and well-being of children in foster care. 相似文献

Although recent studies examine overall fertility trends in West Africa, few using advanced demographic techniques focus on adolescents. This study explores long‐term patterns of adolescent childbearing in 12 West African countries using 51 Demographic and Health Surveys covering birth cohorts that span 54 years (1940–1994). We employ classic demographic measures as well as disaggregation by early‐ (10–14 years old), middle‐ (15–17), and late adolescence (18–19). Cohort‐based estimates of total adolescent births, parity progression ratios, and rapid repeat birth probabilities reveal little change over time. Most women begin childbearing in adolescence, the progression to additional adolescent births remains common, and the incidence of rapid repeat births is high. In recent cohorts, women exit adolescence with an average of between 0.4 (Ghana) to 1.3 (Niger) births. Contrary to common assumptions, it is women commencing motherhood in early‐ and middle‐, not later adolescence, who account for most West African adolescent fertility. 相似文献

We examined social and economic resources in the environments of children involved with child protective services and their associations with children's cognitive performance. We used a national dataset of child protection investigations (children aged 6–16 at Wave 1). Using latent class analysis, we constructed profiles of the financial resources, parental education and employment, and family structure and size. We then examined within‐ and across‐time associations between resource environment profiles and children's math and reading scores and tested whether associations differed by family care type. Our latent class analysis identified four distinct family resource environments: educated middle class, single earner, large working class, and severely disadvantaged. Family resource environment profiles predicted current cognitive performance and changes in performance over time, but associations were more consistent for children in biological family care. Children who remain in home following maltreatment allegations may benefit from services that target social as well as economic resources. 相似文献

This study examined whether residents' level of resilience mediated the relationship between social support for exercise from staff and resident satisfaction in assisted living. This was a secondary data analysis using baseline data from a function-focused care intervention study including 171 residents from four assisted living facilities. Using structural equation modeling, we found that mood and social support for exercise from staff were the only variables associated with resilience. Mood, gender, cognition, and social support for exercise from staff directly influenced resident satisfaction and explained 31% of the variance in the model. Implications for future research and practice are discussed. 相似文献

Objective: To examine differences in complete response rates for depression screening questions based on demographic characteristics. Methods: Cross-sectional study examining associations between demographic characteristics and completely responding depression-screening questions. Participants: “Healthy Minds Study” data, collected in a public University in February 2016, where 7,326 students participated. Results: women (AOR: 0.69; 95% CI =0.57–0.83) and gay/lesbian students (AOR: 0.24; 95% CI =0.10–0.60) had better complete response rates. Non-US (AOR: 1.46; 95% CI =1.03–2.07), black (AOR: 3.32; 95% CI =1.92–5.77), and Middle-Eastern students (AOR: 3.73; 95% CI =1.73–8.02) had lower complete response rates. Conclusions: Our study shows sex, gender, citizenship, and race categories have significant differences in complete response rates for the outcome. Our findings have several implications; including recognizing interventions for depression based on responders may not target those that tend to be “partial-responders”. Efforts in survey design, recruiting and completion of surveys should be maximized. 相似文献

This article argues that interdependent relationships are key in realising inclusion and citizenship for people living with dementia. We focus on decision-making as one aspect of everyday life which reflects opportunities and challenges associated with citizenship. Accounts of everyday decision-making from people living with dementia provide insight into strategies for negotiating responsibilities as they shifted with dementia. An inductive, secondary data analysis developed decision narratives from the data of 61 interviews conducted in the United Kingdom. The interviews were with 12 people with a diagnosis of dementia plus their nominated care-partner in a qualitative study which focused on information management and sense of self. The secondary data analysis identified strategies for inclusion, emphasising relational interdependency amidst challenges. The five-stage framework of an Ethic of Care positions this interdependency as a response to barriers to inclusion and citizenship. Interdependency, therefore, emerges as key to realising relational citizenship. 相似文献

This study tested sexual abuse as a unique predictor of subsequent adolescent sexual behaviors, pregnancy, and motherhood when in company with other types of maltreatment (physical abuse, neglect) and alternative behavioral, family, and contextual risk factors in a prospective, longitudinal study of maltreated (n = 275) and comparison (n = 239) nulliparous females aged 14–19 years old assessed annually through 19 years old. Hierarchical regression was used to disentangle risk factors that account for the associations of maltreatment type on risky sexual behaviors at 19 years old, adolescent pregnancy, and adolescent motherhood. Findings indicate that sexual and physical abuse remain significant predictors of risky sexual behaviors, and that sexual abuse remains a significant predictor of adolescent motherhood when alternative explanatory variables are controlled. 相似文献

Theorizing the contours of televisual pregnancy beauty, this essay demonstrates how televisual stylistics construct and communicate a political ideology of pregnancy. When the crime dramas Bones and In Plain Sight incorporated their star actors’ pregnancies, they produced different televisually styled portrayals of pregnancy; these medium-specific portrayals play an important role in how pregnancy itself is culturally conceptualized. Although pregnancy beauty, the commodification and sexual objectification of the pregnant and postpartum body, has been analyzed in ways that link it to post-industrial, neoliberal, capitalist, and patriarchal forces, this analysis demonstrates how televisual style sets the scene for this broader discourse. Specifically, I contend that the costuming, blocking and staging, cinematography, and editing determine how the pregnant body appears, and this then communicates a clear ideology to viewing audiences. Through these two case studies, I analyze contrasting televisual styles and argue that while Bones’ style disciplines the pregnant body and In Plain Sight’s style welcomes the pregnant body, both styles enact a televisual pregnancy beauty that commodifies pregnancy. 相似文献

Experiential learning theory suggests that students increase their understanding when given the opportunity to experience a particular situation in addition to learning about it intellectually. This theory was used to construct an assignment to assist social work master’s students in better understanding food insecurity and the Supplemental Nutrition Assistance Program (SNAP). Through coding previously collected reactions to the assignment, the researchers discovered multiple reoccurring themes: increased understanding of SNAP, feelings about the program, realizations regarding individual privilege, client stigma, the social experience of eating, and empathy for those who experience food insecurity. Through this exercise, students increased their knowledge of the program and also gained a better understanding of how food insecurity personally affects individuals and families. 相似文献
