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

Self-report measures of perceived pubertal timing correspond only weakly with clinical measures of “objective” physical development. Peer and school contexts shape adolescents’ self-perceptions of pubertal timing. The current study examined associations between perceived pubertal timing and the pubertal timing reported by nominated friends and schoolmates. Participants included 2817 adolescents (Mage = 16.6; 49 % female; 16 % Black; 20 % Hispanic) from the National Longitudinal Study of Adolescent Health. Three measures of pubertal timing were included: age-standardized ratings of body changes, comparisons of development relative to peers (relative timing), and, in females, age at menarche. It was hypothesized that relative timing, which explicitly asks adolescents to compare themselves to their peers, would be related to the age-standardized pubertal timing of nominated friends and schoolmates. Surprisingly, there were no associations between relative timing and age-standardized pubertal timing reported by peers, suggesting that pubertal self-perceptions do not fluctuate in response to the average level of development in a friend group. Instead, males were similar to nominated friends and schoolmates in age-standardized ratings of body changes, and females were similar to nominated friends in relative timing, controlling for race, ethnicity, and age. Different self-report measures of pubertal timing index different underlying constructs, and the social processes that influence adolescents’ perceptions of pubertal maturation may differ between genders. 相似文献

Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5 % female, 14–19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships. 相似文献

’Not Septimus Now‘: wives of disabled veterans and cultural memory of the First World War in Britain
Jessica Meyer 《Women's history review》2013,22(1):117-138
Much of the writing on gender and the First World War has looked at the ways in which pre-war gender norms were reasserted in British society after the War. The article looks at the experiences of one group of women, the wives of men psychologically disabled by the experience of war, to show how disability could prevent the reassertion of pre-war gender roles. The experiences of these women, as expressed in the disability files created by the Ministry of Pensions, is then compared with the dramatisations of wives of disabled veterans in two post-war novels. This comparison highlights the ways in which such dramatisations turned the figure of the wife of the disabled veteran into a symbol of suffering that may be compared to the similarly symbolic figures of the neurasthenic veteran. 相似文献

Many U.S. cities function without regular problems. They have well‐kept roads, sewers that never overflow, and public parks with swing sets and restrooms. Others struggle to maintain balanced budgets, fail to adequately equip or staff their police forces, and offer little assistance to residents of limited means. What explains these differences? I argue that segregation along racial lines contributes to public goods inequalities. Racially segregated cities are also politically polarized cities, making collective investment more challenging and public goods expenditures lower. I provide evidence for this argument using election data from 25 large cities and demographic data matched to city finances in more than 2,600 places. To handle the problem of endogeneity, I instrument for segregation using the number of waterways in a city. I find that segregated municipalities are more politically polarized and spend less on a wide range of public goods. 相似文献

This article describes characteristics, service experiences, and outcomes for 350 ex-offenders with minor-aged children who were served at the John Inman Work and Family Center (WFC), a multiservice program offering assistance with employment, child support, and family reconnection. Following their visit to the WFC, fathers had higher rates of employment and child support payment. They also returned to prison at lower rates than the general offender population. Although the findings suggest that parents who leave prison benefit from a collaborative facility that offers multiple services, more rigorous research over longer periods of time is needed to reliably assess the effectiveness of reentry programs. 相似文献
