Objective: To analyze the overlap of nonsuicidal self-injury (NSSI) and suicide-related behaviors (SRB) among college students with regard to demographics, mental health, and coping styles. Participants: Respondents were 572 undergraduate students at a southwestern public university. Methods: Data were collected in 2015. Respondents completed a demographic survey and assessments of NSSI, SRB, internalizing symptoms (ie, anxiety, stress, and depression), aggression, and negative coping strategies. The survey was administered via a Web-based procedure. Results: Women reported more frequent cutting behaviors than men. Endorsement of NSSI was also associated with an increased likelihood of lifetime SRB. A subgroup of students endorsing both NSSI and SRB demonstrated poorer mental health, more negative coping, and self-reported female sex. Conclusions: College healthcare providers may benefit from competency-based training in techniques for the combination treatment of NSSI and SRB, as well as culturally based models of suicide. 相似文献

Objective: Due to the short life expectancy of black men, it is important to understand what impacts health behaviors in this group so that interventions and programs can be developed to improve their health behaviors which may help in increasing the life expectancy of black men. The purpose of this study was to understand what perceived barriers exist for black college men that prevent them from engaging in healthy behaviors. Participants and Methods: Thirty-five black male students at a southern Historically Black College and University participated in five focus groups and four interviews. A qualitative analysis was used to analyze data for similar themes and codes. Results: Perceived barriers to engaging in healthy behaviors appear to be influenced by image, food cost, and education. Cues to action for not engaging in healthy behaviors appear to be related to role models. Conclusions: Black college men are not adequately informed or educated about elements that can impact their health and how they can improve it. College administrators and researchers should develop interventions that include elements of increasing health knowledge and age-appropriate role models to improve health behavior change among this group. 相似文献

Objective: To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students. Participants: Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively. Methods: Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart. Results: For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up. Conclusions: Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use. 相似文献

Among their many responsibilities, foster parents are tasked with providing healthy food and proper nutrition to children with a variety of physical, psychological, and emotional needs. Using the lens of symbolic interactionism, this exploratory mixed methods study examined how foster parents attend to the nutritional needs of abused and neglected children. Methods used included both quantitative surveys and qualitative follow-up interviews. Surveys were completed by 23 foster parents in a large, Midwest metropolitan area. Parents reported they provided their children balanced meals, although one-third of households reported instances of food insecurity. During qualitative interviews, foster parents (N = 9) described how children arrived at their home with a variety of unhealthy eating habits, some severe in nature. Parents discussed strategies used to modify and improve eating patterns, including offering healthy food choices, having children plan meals, and gathering as a family for daily dinners. In general, parents understood the link between unhealthy eating and past childhood trauma, but also reported being unprepared for more serious eating problems like hoarding. Findings indicate that foster parents need food assistance to increase food security as well as training in assessing and responding a variety of unhealthy child eating behaviors. 相似文献

This study explored perceptions of community informants on socioenvironmental factors that explain why rates of child maltreatment reporting are different in neighborhoods with similar population characteristics. This study used data from the SoCal Neighborhoods and Child Welfare study, a multiphase, mixed-methods study of neighborhoods in Los Angeles and San Diego counties. Semistructured qualitative interviews with key informants (N = 28) in 22 census tracts explored factors that account for differences in maltreatment rates among sociodemographically similar neighborhoods. Thematic content analysis revealed three themes regarding neighborhood contributors to maltreatment behaviors and reporting: (a) community norms and values, (b) community resources and providers, and (c) housing dynamics and built environment. Findings indicate complexity in forces that affect maltreatment behavior and reporting. Adding to research on neighborhood social dynamics and child maltreatment, findings suggest that composite indicators of maltreatment within neighborhoods are affected by maltreatment behaviors and the definition, recognition, and reporting of maltreatment. 相似文献

Currently, disabilities organizations are increasingly being challenged by the requirement for individualized service, expectations to show personal outcomes, and the need to base their services on evidence-based practices. Social entrepreneurship (SE) is being put forward as an innovative approach for dealing with these challenges. This article presents a systems approach to SE based on a program logic model. This model identifies the input factors (a strong social vision, exploiting opportunities, maximizing resources), throughput strategies (entrepreneurial orientation, critical thinking skills, networking, capacity building), and outcome components (improving people’s lives, community-building, improving society) of SE at the micro, meso, and macro level. Also, the importance of planning for contextual changes as a social entrepreneur is discussed. The article concludes with presenting three inspiring practices regarding SE in the field of disabilities organizations. 相似文献

This study argues that different cities in China have different resource environments available for NGOs. Organizations react to these resource environments by constructing appropriate resource strategies, which in turn shape the characteristics and structures of the NGOs of that city. It further examines how these characteristics and structures influence the construction and performance of citizenship in an authoritarian environment. Specifically, some types of NGOs encourage Chinese citizens to be passive, while others offer a model for people to actively engage with social issues. This is aptly demonstrated in an analysis of NGOs operating across four cities—Beijing, Shanghai, Kunming, and Nanjing—which reveals three different types of resource environments and behavioral models for NGOs. We subsequently discuss the implications of each model for citizen engagement. 相似文献

Adult social care services in the United Kingdom have undergone a period of transformation over recent years, characterised by a drive towards personalised care. Concurrently, social care budgets have been significantly reduced. This study aimed to explore the daily living experiences of adults with mild/moderate intellectual disabilities, who are at risk of no longer meeting eligibility criteria for statutory support. Focus group discussions, which included both people with intellectual disabilities and support workers, were analysed thematically. Two broad themes are presented: independence and agency; and social capital and well-being. While some participants echoed ideas central to the personalisation narrative, a number of contextual barriers to achieving greater independence and agency were discussed. Moreover, greater independence was not a desired goal for all participants. The findings highlight the potential mismatch between personalised social care, as delivered within significant budget constraints, and the needs of adults with intellectual disabilities. 相似文献

Austerity places intense pressures on labour costs in paid care. In the UK, electronic monitoring technology has been introduced to record (and materially reduce) the working time and wages of homecare workers. Based on empirical findings, we show that, in a ‘time of austerity’, care is reductively constructed as a consumption of time. Service users are constructed as needy, greedy, time‐consumers and homecare workers as resource‐wasting time‐takers. We point to austerity as a temporal ideology aimed at persuading populations that individual deprivation in the present moment, self‐sacrifice and the suppression of personal need in the here and now is a necessary requirement to underpin a more secure national future. Accordingly, women in low‐waged care work are required to eschew a rights‐bearing, present‐tense identity and are assumed willing to suppress their entitlements to lawful wages as a sacrifice to the future. By transforming our understandings of ‘care’ into those of ‘time consumption’, and by emphasizing the virtue of present‐tense deprivation, a politics of austerity appears to justify time‐monitoring in care provision and the rationing of homecare workers’ pay. 相似文献
