Ryan and Fredericks (1997) measure of vitality, thesubjective feeling of being alive and alert, wasdeveloped in the context of a single factor analysis.The present investigation employed structural equationmodeling (SEM) to assess construct validity andutility of the new measure. A large sample (N = 526) wascollected in two waves, allowing the investigators tofurther develop the model proposed by Ryan andFrederick, and to then validate it on a second dataset. The final model is presented, and the process ofachieving that model is discussed, as are the relativestrengths of SEM in test development.  相似文献

Self‐report data regarding alcohol, cigarette, and marijuana use were collected biennially from ages 14 to 20 in a nationally representative panel sample of adolescents (N=1,897) from the Monitoring the Future study. Growth curve analyses were performed using hierarchical linear modeling to consider psychosocial background, motivation and school attitudes, and parental and peer influences at age 14 as predictors of concurrent substance use and change in substance use. Results indicated that school misbehavior and peer encouragement of misbehavior were positively associated with substance use at age 14 and with increased use over time; school bonding, school interest, school effort, academic achievement, and parental help with school were negatively associated. The protective effects of positive school attitudes and perceptions of high status connected to academics were stronger for low‐achieving compared with high‐achieving youth. Implications for a developmental perspective on substance use etiology and prevention are discussed.  相似文献

Adolescence for the Puerto Rican girl in the United States constitutes a phase of life in which developmental tasks are strained by the demands of her family and exposure to two cultures. This stress renders her adaptive potentials vulnerable to dysfunction. The authors describe the Puerto Rican family, the girl's socialization, the stress of living in dual cultures, and implications for behavioral problems. These factors are integrated to help the practitioner design culturally sensitive interventions.Carl Bryant is an Adjunct Assistant Professor Hunter College School of Social Work and is also in private practice.  相似文献

Policy formulation and decision-making occur within a continually changing sociopolitical environment. Presently, our national health policy lacks coherence and direction. It also is in a state of transition as evidenced by the recent restricted proposal to expand Medicare coverage to catastrophic illness. A comprehensive strategy for balancing escalating medical, hospital, and insurance costs as well as those associated with long-term care while extending access has not been devised. One of the most salient reasons for this is the failure of policy makers to grasp the complexities of the multifaceted stratification system. Its diverse, interrelated strata based on age, sex, economic status, and race are not incorporated in the process of shaping vitally needed and rational health policy. Doris Y. Wilkinson, a professor of sociology at the University of Kentucky, is a co-principal investigator on an intervention project funded by the National Cancer Institute. She recently received the Master of Public Health in Health Policy and Management from Johns Hopkins University.  相似文献

This study investigated cross‐level mediational and moderational community and family influences on adolescent depressive symptoms. Using multilevel data from the National Longitudinal Study of Adolescent Health, we predicted that structural community characteristics such as community poverty and ethnic heterogeneity would influence community social resources, which in turn would influence adolescent depressive symptoms. We further predicted that community social resources would influence adolescent depressive symptoms through family social resources. Findings also suggested that the influence of the parent‐child relationship on adolescent depressive symptoms is weaker in more adverse communities than in less adverse communities. The findings underscore the importance of placing family process models within the community context when adolescent outcomes are investigated.  相似文献

There is perhaps no more pressing issue in school policy today than the achievement gap across social lines. Achievement differences between well-to-do children and poor children and between disadvantaged racial and ethnic minorities and majority whites are large when children first begin school, and they increase over time. Despite years of study and an abundance of good intentions, these patterned achievement differences persist, but who is responsible, and how are schools implicated? The increasing gap seems to suggest that schools are unable to equalize educational opportunity or, worse still, that they actively handicap disadvantaged children. But a seasonal perspective on learning yields a rather different impression. Comparing achievement gains separately over the school year and the summer months reveals that much of the achievement gap originates over the summer period, when children are not in school. The authors review Beginning School Study research on differential summer learning across social lines (that is, by family socioeconomic level) and its implications for later schooling outcomes, including high school curriculum placements, high school dropout, and college attendance. These studies document the extent to which these large summer learning differences impede the later educational progress of children of low socioeconomic status. Practical implications are discussed, including the need for early and sustained interventions to prevent the achievement gap from opening wide in the first place and for high-quality summer programming focused on preventing differential summer learning loss.  相似文献

ABSTRACT

This study examined associations between stepfather–stepchild relationship quality, stepfathers’ depressive symptoms, and two aspects of marriage: marital quality and positive marital interactions. Marital quality was assessed in terms of commitment, trust, passionate and friendship-based love, and happiness. Marital interactions were assessed in terms of intimacy, shared activities, and verbal communication. Using data collected from 149 recently married African American stepfathers, structural equation modeling revealed that when stepfathers reported more positive relationships with their stepchildren, they also reported more positive marital quality and a higher frequency of positive marital interactions (relationship-solidifying activities), and that, in turn, was associated with stepfathers experiencing fewer depressive symptoms.  相似文献

This paper documents an experience of using respondent-driven sampling (RDS) to recruit socially marginalised young people in Sydney, Australia. Respondents were young people aged 16–24?years who were current illicit drug users and who reported at least one feature of social marginalisation (e.g. recent homelessness or juvenile detention). Four seeds initiated the sampling and 61 respondents were recruited until the sampling was closed due to slow progress at week nine. The paper examines: (1) the overall success of RDS and compares this with similar RDS studies; and (2) the sufficiency of network ties among respondents. The analyses suggest that RDS was generally successful in that, despite its small size, the sample achieved adequately long recruitment chains and variables converged to equilibrium. Nevertheless, recruitment was much slower than comparable studies. This could be due to the study population having reduced willingness to participate, a high proportion of respondents who did not fit the selection criteria, and small and disparate networks. Using RDS with marginalised youth may require generous resourcing to allow large incentives to increase willingness, and a lengthy recruitment period. Moreover, the small networks suggest that researchers should start the sampling with a large number of seeds.  相似文献

This study investigated school factors that impact attendance. Interviews and focus groups with over 60 key stakeholders from five Maryland counties were conducted. Respondents indicated that despite individual, family, and community factors that contribute to non-attendance, students will attend a school that is intentional about creating a welcoming climate that is supportive and academically stimulating. Attendance can be improved when schools evaluated policies that may unintentionally deter student attendance, when students feel heard by school personnel, and when students are given opportunities to establish supportive relationships with caring adults in and out of the classroom.  相似文献
