ABSTRACTObjective: To evaluate the impact of educational text messages (TMs) on folate/folic acid knowledge and consumption among college-aged women, and to evaluate the impact of providing folic acid supplements on folate/folic acid intake among college-aged women. Participants: A total of 162 women (18–24 years) recruited from a university. Methods: The protocol included 3 study visits and a 6-week intervention for 4 groups: control; TM only; supplement only; and TM+supplement. Supplement groups received folic acid–containing supplements. TM groups received 18 folate-related TMs. Participants completed knowledge quizzes, supplement intake questions, a self-efficacy scale, and dietary recalls. Results: Despite receiving the same folic acid education, intake of folic acid and total folate was greater in the supplement groups compared with the non-supplement groups at mid- and post-study. TMs had no impact on any study measure. Conclusion: Provision of a folic acid–containing supplement enhanced short-term folic acid intake, supporting the provision of supplements to this population group. 相似文献

AbstractObjectives: Stress is the most commonly reported impediment to academic performance among college students. The objectives of this study were to examine the accuracy of these perceptions, identify demographic and psychosocial factors that distinguished among students who differed in perceptions of how stress affected their performance, and assess the relations between these factors and grade point average (GPA). Participants: Undergraduate students (N?=?8,997) from 20 Midwestern schools. Methods: Participants completed online surveys during February–March 2015 that assessed perceived impediments to academic performance, cumulative GPA, demographic information, and psychosocial factors. Results: Students who reported that stress affected their performance had lower GPAs, and reported more stress and lower coping self-efficacy, resilience, and social support. Male, heterosexual, and ethnic-minority students were less likely to report having stress (but did not have higher GPAs). Conclusion: Stress reduction interventions should target psychosocial factors related to perceiving stress as an impediment and to poorer performance. 相似文献

Playgrounds are important features of residential areas. Their design influences child play behaviour, particularly ‘pretend play’. With a growing number of young families moving into new suburbs, investigation into the extent to which pretend play is considered in playground design is an important planning issue. This is the focus of this research. Three playgrounds in Perth, Western Australia, were chosen as case studies, and intercept surveys of parents supervising children at these playgrounds and observation of the children behaviour were carried out. Park managers, landscape architects and community facilities managers from outer metropolitan councils were also interviewed. A key finding was that multi-purpose play equipment, particularly sand and themed playgrounds, best fostered pretend play. Further, while local government officers were supportive of pretend play, several factors limit the inclusion of pretend play features into playground designs, primarily risk management. Officers acknowledged that high-risk play was conducive to pretend play, but the need to reduce risk was the main consideration for playground design. The overall conclusion was that pretend play is neglected in playground designs, therefore greater education is needed of the value of pretend play in playground design needed, including the role of risk. 相似文献

In the United States about 17% of adolescents meet diagnostic criteria for mental, emotional, and behavioral disorders. Six million young people receive treatment services annually for mental, emotional, or behavioral problems. These problems affect 1 in 5 families and cost $247 million annually (O'Connell, Boat, & Warner, 2009). Some strategies for preventing mental, emotional, and behavioral disorders in young people have been developed, tested, and found to be effective in preventing the onset, persistence, and severity of psychological disorders, drug abuse, and delinquency. Unfortunately, tested and effective prevention policies, programs, and practices are not widely used (O'Connell, Boat, & Warner, 2009). This paper highlights recent advances in prevention science and describes some opportunities and challenges in advancing the use of science-based prevention in communities. The chapter concludes by exploring the potential role of social work education in developing a workforce ready to increase community access to effective prevention strategies. 相似文献

Evidence from male‐dominated sectors points to high levels of disability and the disabling nature of working environments. However, research of this nature assumes a medical model of disability that does not account for the social construction of disability or the lived experiences of disabled employees. Using data from seven focus groups (n = 44) and semi‐structured interviews with professional transport employees with life‐long hidden ‘impairments’, including dyslexia, dyscalculia, dyspraxia, ADD/ADHD and Asperger syndrome (n = 22), this paper explores the lived experiences of men and women working in a sector traditionally dominated by men, the transport industry. Key themes include homosociality, public–private divide and the impact of changing work practices. Further, the data revealed how those with hidden ‘impairments’ in part construct their identities in relation to both non‐disabled colleagues and those considered stereotypically representing disability (wheelchair users). This study furthers understandings of the relationality of gender and disability in the workplace, and the lived experiences of disabled employees. 相似文献

Previous research suggests that the choice of graphical format for communicating risk information affects both understanding of the risk magnitude and the likelihood of acting to decrease risk. However, the mechanisms through which these effects work are poorly understood. To explore these mechanisms using a real‐world scenario, we examined the relative impact of two graphical displays for depicting the risk of exposure to unexploded ammunition during potential land redevelopment. One display depicted only the foreground information graphically (a bar graph of the number of people harmed), and a second depicted the foreground and background graphically (a stacked bar graph representing both the number harmed and at risk). We presented 296 participants with either the foreground‐only or the foreground and background graphical display and measured a broad set of outcome variables, examining (1) the graphical display effect on each of the outcome measures and (2) the pathways by which any display effects work to influence decision making. We found that the foreground‐only graphical display increased perceived likelihood and experienced fear, which produced greater worry, which in turn increased risk aversion. In addition, a positive evaluation of the communication materials increased support for policies related to land redevelopment, whether those policies were risk taking or risk mitigating. Finally, the foreground‐only graphical display decreased understanding of the risk magnitude, showing that approaches to accomplish one risk communication goal (promoting risk‐averse decisions) may do so at the expense of another goal (increasing understanding). 相似文献

Despite improvements in forecasting extreme weather events, noncompliance with weather warnings among the public remains a problem. Although there are likely many reasons for noncompliance with weather warnings, one important factor might be people's past experiences with false alarms. The research presented here explores the role of false alarms in weather‐related decision making. Over a series of trials, participants used an overnight low temperature forecast and advice from a decision aid to decide whether to apply salt treatment to a town's roads to prevent icy conditions or take the risk of withholding treatment, which resulted in a large penalty when freezing temperatures occurred. The decision aid gave treatment recommendations, some of which were false alarms, i.e., treatment was recommended but observed temperatures were above freezing. The rate at which the advice resulted in false alarms was manipulated between groups. Results suggest that very high and very low false alarm rates led to inferior decision making, but that lowering the false alarm rate slightly did not significantly affect compliance or decision quality. However, adding a probabilistic uncertainty estimate in the forecasts improved both compliance and decision quality. These findings carry implications about how weather warnings should be communicated to the public. 相似文献
