Objective: To determine the feasibility of a mobile health (mHealth), media literacy education program, Media Aware, for improving sexual health outcomes in older adolescent community college students. Participants: 184 community college students (ages 18–19) participated in the study from April–December 2015. Methods: Eight community college campuses were randomly assigned to either the intervention or a wait-list control group. Student participants from each campus completed web-based pretest and posttest questionnaires. Intervention group students received Media Aware in between questionnaires. Results: Several intervention effects of the Media Aware program were significant, including reducing older adolescents' self-reported risky sexual behaviors; positively affecting knowledge, attitudes, normative beliefs, and intentions related to sexual health; and increasing media skepticism. Some gender differences in the findings were revealed. Conclusions: The results from this study suggest that Media Aware is a promising means of delivering comprehensive sexual health education to older adolescents attending community college.  相似文献

Objective:This study examined the prevalence and correlates of probable posttraumatic stress disorder (PTSD) in freshman entering college and prospective associations of probable PTSD with additional outcomes. Participants: 2,310 students with data collected from Fall 2014 through Spring 2015. Methods: Incoming freshman completed a survey assessing for relevant variables at the beginning of fall semester and during the spring semester. Results: Seventy percent of the sample endorsed experiencing at least one potentially traumatic event (PTE). 34.4% of PTE exposed individuals met criteria for probable PTSD. Female sex, higher depressive and anxiety symptoms, and interpersonal PTE count were positively associated with PTSD symptoms. Higher PTSD symptoms were associated with higher anxiety and depressive symptoms, and new-onset interpersonal PTE. Conclusions: Identification of factors contributing to risk for PTSD is essential to inform prevention and intervention efforts. Intervention efforts should be targeted to students experiencing PTSD symptoms as they enter college.  相似文献

Digitalization is transforming societies and economies worldwide at an unprecedented scale and pace. In the wake of automation and digitalization, new forms of employment have been emerging in various occupations and sectors, such as the digital platform economy. The emergence of new forms of employment, such as work on digital platforms, requires that existing social protection systems adapt to the specific situation and needs of such workers, as to realize the human right to social security for all. Current social protection coverage for workers on digital crowdwork platforms reveals significant gaps in social security coverage. Where such coverage exists, it is often provided through the workers’ previous or additional jobs, or indirectly through their spouses or other family members. This raises questions about digital platforms free riding on the traditional economy with regard to the financing of social security. How can social protection systems adapt to changing forms of work to ensure full and effective coverage for workers in all forms of employment, including those in “new” forms of employment? How can workers in all types of employment, including those on digital platforms, be protected in an adequate and comprehensive way, combining contributory and non‐contributory mechanisms and based on equitable and sustainable financing mechanisms, so as to ensure adequate social protection to all?  相似文献

Substance abuse among older adults is on the rise. Of particular concern is the increase in alcohol and drug use predicted among Latino elders, expected to result from an upsurge in the Latino population and concurrent growth in the number of older adults. Providing effective treatment for this group will require age-specific, culturally competent interventions. However, few studies have focused on geriatric substance abuse among Latinos. This study aims to lay the groundwork for further research by examining perceptions of the problem among treatment providers and researchers in aging and substance abuse. Implications for social work research and practice are addressed.  相似文献

Women have worse self-rated health and more hospitalization episodes than men from early adolescence to late middle age, but are less likely to die at each age. We use 14 years of data from the U.S. National Health Interview Survey to examine this paradox. Our results indicate that the difference in self-assessed health between women and men can be entirely explained by differences in the distribution of the chronic conditions they face. This is not true, however, for hospital episodes and mortality. Men with several smoking-related conditions--including cardiovascular disease and certain lung disorders--are more likely to experience hospital episodes and to die than women who suffer from the same chronic conditions, implying that men may experience more-severe forms of these conditions. While some of the difference in mortality can be explained by differences in the distribution of chronic conditions, an equally large share can be attributed to the larger adverse effects of these conditions on male mortality. The greater effects of smoking-related conditions on men's health may be due to their higher rates of smoking throughout their lives.  相似文献

Nuclear waste cleanup is a challenging and complex problem that requires both scientific analysis and dialogue among a variety of stakeholders. This article describes an effort to develop an online information system that supports this analytic-deliberative dialogue by integrating cleanup information for the Hanford Site, and making it more "transparent." A framework for understanding and evaluating transparency guided system development. Working directly with stakeholders, we identified information needs and developed new ways to organize and present the information so that it would be more transparent to interested parties, with the ultimate aim of fostering greater participation in decision dialogues and processes. The complexity of the information needed for dialogue suggested that several types of communication devices ("information structures") were warranted. Five information structures were developed for the pilot Decision Mapping System (http://nalu.geog.washington.edu/dms). Decision maps hyperlinked decision information to maps of Hanford. Background Information provided context in a narrative format. Decision Paths organized decision process information on a timeline and provided direct hyperlinks to online documentation. The Geographic Library hyperlinked decision documents to maps. Finally, a Discussion Forum allowed users to make comments and view remarks from others. Early lessons from this work suggest that transparency is integral to long-term management, a participatory design process contributed greatly to its perceived success, and better data integration to support decision making is needed. This work has broad implications for risk communicators and risk managers because it speaks to the design of information systems to support "analytic-deliberative" decision processes (i.e., those that rely upon both risk science and public dialogue).  相似文献
