Cross-system collaboration among child welfare (CW), alcohol and other drugs (AOD), and court organizations shows promise in addressing the many needs of CW-involved families experiencing parental substance use disorders (SUDs). Research has suggested that differing perceptions of parents with SUDs among staff in these organizations may hinder the collaborative process. Using a sequential explanatory mixed-method approach, this study explored staff perceptions of parental SUDs among CW, AOD, and court organizations. Logistic regression analyses indicated that, compared to CW respondents, AOD respondents were: (a) less likely to believe that parents could provide effective parenting; (b) more likely to believe that abstinence should be a criterion for reunification; (c) more likely to agree that parents should receive jail time as a consequence for noncompliance with court orders; and (d) more likely to believe that parents could succeed in treatment. Thematic analyses of these focal areas identified two core themes (focus on the primary client and mandated time frames for permanency), as well as multiple subthemes, that provided a nuanced understanding of differing perceptions on these matters. Suggestions for the development of anticipatory cross-system training and practices and implications for policy evaluation are discussed.  相似文献

在英语中,代词的使用范围很广,频率很高。因此就某一方面而言英语学习者的语言水平可以通过其对代词的使用正确与否进行考证。人称代词和物主代词的误用是代词误用的一个重要方面,本文从英、汉两语对代词的分类,汉语的负迁移,学习者思维定式角度测试分析了人称代词和物主代词误用的原因并阐述出人称、物主代词的误用在某种意义上说属于中介语的石化现象。  相似文献

ABSTRACT

Research indicates that many college students report posttraumatic stress disorder (PTSD) or substance use disorder (SUD), yet there has been scant attention paid to the co-occurrence of these disorders in college students. This review examines the co-occurrence of PTSD and SUD in college students. Recommendations for counseling centers are provided regarding the assessment of this population, an overview of treatment issues, and three areas of clinical importance when working with this population: risk behaviors, interpersonal violence, and social isolation. Future directions for research are also suggested.  相似文献

By 1986, all of the University of California (U.C.) Campus Libraries as well as the Stanford University Libraries had completed the Psychology Conspectus as part of the North American Collections Inventory Project (NCIP). Phase I. Between 1986 and 1988, they participated in a "pilot" project which was designed to further review, analyze and explore possibilities for coordinating policy in the subject area of psychology. The article is a recounting of some issues and problems encountered in this attempt.  相似文献

ABSTRACT

In 1996 a team of researchers at the Alcohol Research Group (ARG) in Berkeley and the Addiction Research Foundation (ARF) in Toronto began a three year study of U.S. federal alcohol control policy. This paper draws on anecdotal evidence from the Policy Project to make a case study of the impact of Internet information resources on the development and adaptation of research strategies. We consider how Internet access affects utilization of information services within an organization; prospects and pitfalls in adapting research strategies to Internet resource availability; critical Internet resources for substance abuse policy analysis; and measures of utilization and effectiveness applicable to assessing the impact of Internet resources.  相似文献

logistic回归分析在医学研究领域应用较为广泛,但因其涉及的因素较多,统计方法较为复杂,部分研究者未咨询流行病学和卫生统计学专业人员而盲目套用统计学方法,造成其在应用logistic回归分析处理数据时出现诸如自变量选取和纳入、统计模型选择、结果表述和报告时误用错用情况的发生。本文选取公开发表的医学论文,举例分析文章中logistic回归误用错用的情况,指出其正确应用方法,为医学期刊编辑处理类似稿件提供参考。  相似文献

The present study examines the role of communication in shaping norms and behaviors with significant personal and societal consequences. Based on primary socialization theory and the general theory of family communication, parental anti-substance-use socialization processes were hypothesized to influence early adolescents’ substance-use norms and behaviors. Using longitudinal data (N?=?1059), the results revealed that parent-adolescent prevention communication about substance use in the media and parental anti-substance-use injunctive norms were positively associated with early adolescents’ personal anti-substance-use norms, which, in turn, led to decreases in recent alcohol, cigarette, and marijuana use. It was also found that family expressiveness and structural traditionalism positively related to the hypothesized association between parental socialization processes and early adolescents’ norms and behaviors.  相似文献
