Current research on how adolescents cope with bullying is primarily quantitative, examines youth in Grades 1 through 6, and neglects to specifically assess how victims of bullying cope with being bullied. The current qualitative study explored the coping strategies of 22 rural middle- and high-school youth victimized by bullying. Results indicated that youth report using an array of emotion focused coping strategies (an internal coping strategy that focuses on emotion regulation) and problem focused coping strategies (active behaviors that are aimed to decrease or eradicate the stressor). These coping strategies included help seeking, physical and verbal aggression, standing up for themselves, and prosocial bystander behavior. While the majority of coping strategies were similar between middle- and high-school participants, these groups reported utilizing verbal and physical aggression in different ways. Further, certain coping strategies, such as help seeking and lashing out with physical and verbal aggression, were utilized as both emotion- and problem-focused coping strategies. Implications are discussed.  相似文献

Objective: The purpose of this pilot study was to evaluate the Resilience and Coping Intervention (RCI) with college students. Participants: College students (aged 18–23) from a large Midwest US university who volunteered for a randomized controlled trial during the 2015 spring semester. Methods: College students were randomly assigned to an intervention (n = 64) or a control (n = 65) group. Intervention participants received three 45-minute RCI sessions over subsequent weeks. All participants completed pre- and post-intervention assessments at the beginning of Week 1 and end of Week 3. Student resilience, coping, hope, stress, depression, and anxiety were assessed. Results. RCI participants reported significantly more hope and less stress and depression from Week 1 to Week 3 compared with control participants. Results for resilience also approached statistical significance. Effect sizes were small to moderate. Conclusions: This study found preliminary evidence that RCI is an effective resilience intervention for use with college students.  相似文献

This street participatory action research (Street PAR) study organized 15 residents to document street‐identified Black youth and adult's negative experiences with police in Wilmington, Delaware. Data were collected on mostly street‐identified Black men and women aged 18–35 in the forms of (1) 520 surveys, (2) 24 individual interviews, (3) four dual interviews, (4) three group interviews, and (5) extensive field observations. Forty‐two percent of survey participants reported being stopped by police in the last year. However, with the exception of being “stopped,” participants overall reported little negative contact with police at least within the past year. Chi‐square and ANOVA analyses suggest an interactional relationship exists between race, gender, and age on experiences with police. Younger Black men (18–21) were found to have the most negative contact with police. Analysis suggests a smaller, more hardened mostly male variant of the larger street community has had repeated contact with police. Qualitative analysis reveals at least two major themes: (1) disrespect and disdain for residents and (2) low motivation for working with police. Street PAR methodology was also found to be instrumental in working with local residents and the Wilmington Police Department to improve conditions between residents and police.  相似文献

This study extends Flores et al.'s ( 2006 ) 36‐year analysis of racial/ethnic minority (REM) career research to identify recent trends in choice of topics and leading individual and institutional contributors. The authors identified 166 articles on REM career research published from 2005 to 2015 in the Journal of Vocational Behavior, The Career Development Quarterly, the Journal of Career Assessment, and the Journal of Career Development. Of these studies, 92% were empirical, with more than three quarters of these using quantitative rather than qualitative methodology. Most frequently, the empirical studies (n = 153) were based on samples of high school (30.7%) or undergraduate (34.6%) students. The authors discuss the implications of their findings and suggest ways to expand REM career research in the future.  相似文献

Middle school is the appropriate time for students to begin exploring careers and improving self‐efficacy; however, empirically supported career and college readiness interventions for U.S. middle school students are limited. Examining the effect of an intervention that combined a virtual experience and a local college visit on middle school students (99 girls, 74 boys), the authors found that participating students had higher levels of college and career self‐efficacy than did nonparticipating students. The study shows that a workshop of the online Florida CHOICES program coupled with a campus visit increased middle school student career and college self‐efficacy. Future research should include longitudinal studies and use of diverse populations to improve generalizability of study results.  相似文献

Objective: Sexual assault is a pervasive crime on our college campuses and many survivors do not seek post-assault resources. This study will explore components of alternative interventions to consider in the development of campus-based interventions for sexual assault survivors. Participants: Three stakeholder groups including survivors (n = 8), healthcare providers (n = 6), and advocates (n = 19) were recruited from May 2014 to December 2014 from two university campus communities using flyers and purposive sampling. Methods: A qualitative study design utilized semi-structured interviews and semi-structured focus groups with survivors, healthcare providers, and advocates. Results: Five themes emerged to consider for future campus-based sexual assault interventions: (a) culture of caring, (b) one-stop shop, (c) validation, (d) survivor control and agency, and (e) confidentiality. Conclusions: Although accessible and effective options for post-assault care do currently exist, participants described alternative future interventions that were either (a) print materials or (b) technology-based.  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
