This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin’ it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use. 相似文献

Research has shown that adverse childhood experiences (ACEs) increase the risk of poor health-related outcomes in later life. Less is known about the consequences of ACEs in early adulthood or among diverse samples. Therefore, we investigated the impacts of differential exposure to ACEs on an urban, minority sample of young adults. Health, mental health, and substance use outcomes were examined alone and in aggregate. Potential moderating effects of sex were also explored. Data were derived from the Chicago Longitudinal Study, a panel investigation of individuals who were born in 1979 or 1980. Main-effect analyses were conducted with multivariate logistic and OLS regression. Sex differences were explored with stratified analysis, followed by tests of interaction effects with the full sample. Results confirmed that there was a robust association between ACEs and poor outcomes in early adulthood. Greater levels of adversity were associated with poorer self-rated health and life satisfaction, as well as more frequent depressive symptoms, anxiety, tobacco use, alcohol use, and marijuana use. Cumulative adversity also was associated with cumulative effects across domains. For instance, compared to individuals without an ACE, individuals exposed to multiple ACEs were more likely to have three or more poor outcomes (OR range = 2.75–10.15) and four or more poor outcomes (OR range = 3.93–15.18). No significant differences between males and females were detected. Given that the consequences of ACEs in early adulthood may lead to later morbidity and mortality, increased investment in programs and policies that prevent ACEs and ameliorate their impacts is warranted. 相似文献

台湾当局推行的“去中国化”政策,妄图从思想、文化、教育、意识形态等各个领域,清除中国对台湾的影响,割断“台湾文化”与“大陆文化”的历史渊源,以营造“台独”的文化、心理和社会环境,为民进党实现“渐进式台独”创造条件。这种“去中国化”政策,继承李登辉“两国伦”的衣钵,与日本殖民者当年在台湾推行的“皇民化运动”和“同化”政策如出一辙,也是继承了李登辉“两国论”的衣钵,是不得人心的。 相似文献

国家尺度上铝的社会流动过程解析 总被引：7，自引：2，他引：5
定性解析金属元素的社会流动过程,是定量化开展其物质流分析和资源流研究的前提。铝是世界上生产量与消费量最大的有色金属,同时也是具有良好再生性能的金属。在大量文献调研和专家访谈的基础上,本文基于金属元素物质流分析的一般性框架,详细解析了铝在国家尺度上的社会流动过程,将其概括为3个“四”:四阶段、四种库和四种流。四阶段包括:生产阶段、加工与制造阶段、使用阶段、报废与再生阶段。四种库包括:矿产资源库、第一和第二阶段产品的暂时性库存、使用阶段的社会累积库、各种含铝废弃物的堆存库(包括弃矿、尾矿、选冶废渣堆存场和垃圾填埋场等)。四种流即正向流、逆向流、废物流、进出口流。以四阶段为依托,重点刻画了四种流的具体过程,为进行定量化的铝物质流分析及相应的能量流、价值流和环境影响分析提供了基础。 相似文献

Youth who are aging out of the foster care system face significant barriers to accessing substance use treatment. Mobile interventions have shown efficacy for several mental and physical health issues and may be helpful in overcoming barriers facing foster youth with substance use problems. A program (iHeLP) for substance use reduction was developed that used a computerized screening and brief intervention (SBI) followed by six months of dynamically-tailored text messages. The program was shown to focus groups of youth (N = 24) ages 18–19 who recently left foster care and had moderate to severe substance use risk. Focus group feedback was used to modify iHeLP prior to delivery in an open trial (N = 16). Both study phases included assessments of feasibility and acceptability; the open trial also included assessments of substance use outcomes at 3 and 6 months. Focus groups indicated a high level of acceptability for the proposed intervention components. Of those screened for the open trial, 43% were eligible and 74% of those eligible enrolled, indicating good feasibility. Retention through the final follow-up was 59%, and drop out was associated with involvement in the criminal justice system. Participant ratings for liking, ease of working with, interest in and respectfulness of the SBI were high. Satisfaction ratings for the texting component were also high. A computerized brief screening intervention for substance use risk reduction together with tailored text messaging is both feasible and highly acceptable among youth who have recently aged-out of foster care. 相似文献

Child maltreatment and risk behaviors: The roles of callous/unemotional traits and conscientiousness
Child maltreatment poses significant risk to the development of callous/unemotional traits as well as risk behaviors such as engaging in violence, having sex with strangers, and binge drinking. In the current study, the indirect pathway from child maltreatment to risk behaviors was examined via callous/unemotional traits; whereas the conscientious personality trait was tested as a moderator of this indirect pathway. Young adults and parents (N = 361; Mage = 19.14, SD = 1.44) completed questionnaires on child maltreatment histories, callousness/unemotional traits, personality characteristics, and risk behaviors. Structural equation modeling was used to examine the hypothesized direct, indirect and conditional indirect effects. Findings showed indirect links between the child maltreatment latent factor and physical fighting, having sex with strangers, and binge drinking via callous/unemotional traits. Furthermore, the conscientiousness personality type significantly buffered the connection between callous/unemotional traits and physical fighting, supporting a conditional indirect effects. Callous/unemotional traits are important factors in the underlying mechanism between child maltreatment and risk behaviors among young adults, and conscientiousness serves as a protective factor against violence. Preventive intervention programs and clinicians may benefit from focusing in addressing callous/unemotional traits among youth who report childhood maltreatment experiences as well as targeting conscientiousness as a protective factor. 相似文献
