The purpose of the current study is to examine the mediation role of social support in the relationship between exposure to violence at school and mental health among adolescents within the framework of two structured models via structural equation model (SEM). The participants consist of a total of 1420 9th, 10th, and 11th grades high school students (54.5% girls and 45.5% boys). The students’ ages ranged from 14 to 18 years with a mean of 16.11 (SD = 0.91) for total sample. 38 percent of the participants are in the 9th grade, 34.1 percent are in the 10th grade, and 28 percent are in the 11th grade. Findings from both models indicated that social support mediated the relationships between exposure to violence and mental health among adolescents. Additionally, both models showed that the associations between exposure to violence, social support and mental health varied by gender. Contributions and implications of the current findings are discussed in detail.  相似文献

Sexual abuse has the potential to generate serious emotional consequences for its victims, but there is high variability in the symptoms reported by different victims. Therefore, it is necessary to ascertain the factors associated with the symptoms presented by sexual abuse victims. The aim of the study was to use a single model to evaluate the relationship between sexual abuse characteristics (frequency, violence, relation with the aggressor and physical commitment), cognitive and behavioral factors (self-efficacy, active coping and perceived family support) and internalizing symptoms (anxiety, depression and posttraumatic stress) in a group of sexually abused adolescents. The participants included 106 female adolescent victims of sexual abuse (M = 14.25 years, SD = 1.74). The results of a path analysis indicated that sexual abuse characteristics were unrelated to symptomatology. Only a negative relationship was observed between the victim’s relationship with the aggressor and PTSD symptomatology. The violence of the sexual abuse was negatively related to self-efficacy, and self-efficacy was positively related to active coping and negatively related to symptomatology. Finally, the perception of family support was positively related to self-efficacy and negatively related to symptomatology. These results suggest the need to consider the studied factors in the process of psychotherapy with victims of sexual abuse.  相似文献

Child poverty is well known as a major risk factor for child maltreatment. However, it is not known whether parental psychological distress and individual-level social capital mediate the association. We examined the mediation effect of these two factors on the association between child poverty and maltreatment. In the Adachi Child Health Impact of Living Difficulty (A-CHILD) Study, a questionnaire was administered to all caregivers of first-grade children in every public elementary school in Adachi City between July and November 2015, and valid responses were used for analysis (N = 3944). Logistic and Poisson regression analyses were employed to examine the association between child poverty and maltreatment. Child poverty was defined in this study as meeting one of these criteria: 1) household income less than 3 million yen; 2) deprivation of specific material items that children or the household requires, or 3) experience of being unable to pay for lifeline utilities. Child maltreatment (physical abuse, neglect, and psychological abuse) was answered by parents. We confirmed a robust association between child poverty and maltreatment. Mediation analysis indicated that parental psychological distress mediated more than 60% of the association between child poverty on physical abuse and psychological abuse, while individual-level social capital mediated only 10% of the association with any type of maltreatment. In addition, structural equation modeling analysis revealed that the association was mediated by both parental psychological distress and social capital simultaneously. The findings suggest that supporting parental psychological distress may be an effective intervention to remedy the negative impact of child poverty on maltreatment.  相似文献

Recent theoretical and empirical research outlined the role of organizational identification in the stress process. We provide an empirical test of the social identity model of stress by testing a two-step mediation model of the identification-burnout link. We hypothesize that strongly identified teachers will receive more support from colleagues which, in turn, relates to perceptions of reduced workload, which finally leads to both lower work- and student-related burnout. We tested our model in a large cross-sectional sample of 2685 Swiss teachers representing half of the teacher population of Ticino Canton. Hypotheses were supported. Implications for theory and practice are discussed.  相似文献

While the importance of a supportive context for entrepreneurship is widely acknowledged, its antecedents are rarely investigated. We apply the concept of organizational climate to higher education institutions and examine the drivers of students’ perceptions of the entrepreneurial climate in their university. Combining data from two unique datasets and using multilevel techniques, we analyze the relationship between university characteristics and such climate perceptions of 8009 students at public universities in Germany. We find university entrepreneurship measures to have a positive effect on students’ climate perceptions, which also depend on students’ background and gender. In addition, we find evidence for different peer effects, depending on students’ affinity for entrepreneurship. For the general student population, including entrepreneurship content in their normal studies seems to be required to initiate a social process of sensemaking. However, students’ perception of the entrepreneurial climate only depend to a certain degree on intentional entrepreneurship measures. In our study, general university characteristics have the strongest influence on climate perceptions. Overall, our study adds to our understanding of which parameters are important for establishing a more favorable and inspiring climate for becoming an entrepreneur at higher education institutions.  相似文献

In the present study we add to the literature by exploring the degree to which UK practitioner psychologists perceive themselves able to support sport coaches, and how professional training prepares psychologists for coach work across performance domains. Ten participants comprising seven sport and exercise psychologists with Health Care Professions Council (HCPC) practitioner psychologist status and three trainee psychologists studying towards the British Psychological Society (BPS) qualification in sport and exercise psychology (QSEP) were individually interviewed. All participants reported prior experience of working with coaches across all performance domains. We explored: practitioner’s understanding of the challenges coaches face within their job; practitioner’s experiences of coach work; perspectives about the ways in which practitioners could and should support coaches; and, the degree to which professional training prepares practitioners for coach work. Using recommended procedures of Connelly and Peltzer, content analysis revealed practitioners perceived the challenges faced by coaches are different at grassroots level compared to those working with elite athletes, and that practitioners require skills to provide one-to-one coach support and group-based interventions. All practitioners perceived that training programmes do not adequately equip trainees with skills required for coach work. We discuss the implications for enhancing practitioner training in the UK.  相似文献

Nature-based tourism experiences have the potential to change the environmental knowledge, attitudes and behavior of visitors; but such experiences may be beyond the physical and/or financial reach of many people. To influence the conservation behavior of populations world-wide, a more accessible yet equally effective strategy is required. Using an experimental design, this study explored whether a conservation documentary about Australian marine environments, together with post-viewing support materials, prompted the adoption of conservation behaviours. Questionnaires revealed environmental knowledge, attitudes and behavioural intentions rose immediately after viewing the documentary. Ten weeks later, these levels were maintained or decreased slightly for those who received post-viewing support (Facebook, help sheet or both), but decreased markedly in the control group. Results are similar to those reported in wildlife tourism studies. Implications for the use of documentaries in place of nature experiences are discussed.  相似文献

As more Teacher Assistants (TAs) take on the responsibility of supporting students with disability and learning difficulties questions arise as to the appropriate qualifications for such work, the adequacy of training, and the policy and practice of schools employing TAs. A qualitative study, informed by multiple perspectives, was conducted in four mainstream primary schools in an Australian capital city to examine the actual qualifications of the TAs as opposed to those required by their employer. Despite role changes since the 1990s, TA qualifications remained unchanged and TAs could be employed with no post-school qualifications. Little training was provided, no training policy existed and access to training across schools differed. Participants' perspectives on the qualifications and training required by TAs also varied. While this paper examines qualifications and training of TAs in Australia, findings are relevant to educators internationally where TAs support students with disability and learning difficulties. Tying TA qualifications to salary incentives and a career structure in which TAs are responsible for supplemental instruction only, is recommended. A Certificate IV in Education Support or School Age Education and Care, complemented by literacy and numeracy tests, are recommended minimum requirements. Finally, teachers should be included in TA recruitment and supervision.  相似文献

This paper contributes a rich picture of how students from refugee backgrounds navigate their way into and through undergraduate studies in a regional Australian university, paying particular attention to their access to and use of different forms of support. We draw on the conceptualisation of ‘hot’ and ‘cold’ knowledge, offered by Ball and Vincent (1998. “‘I Heard it on the Grapevine’: ‘Hot’ Knowledge and School Choice.” British Journal of Sociology of Education 19 (3): 377–400), and the addition of ‘warm’ knowledge offered by Slack et al. (2014. “‘Hot’, ‘Cold’ and ‘Warm’ Information and Higher Education Decision Making.” British Journal of Sociology of Education 35 (2): 204–223), to develop an understanding of how students from refugee backgrounds make choices about how they locate, select and access support for their studies. The findings of this paper suggest that students from refugee backgrounds do not view the ‘cold’ (unfamiliar-formal) institutional support on offer as ‘for them’; instead they expressed a preference for the ‘warm’ (familiar-formal) support offered via ‘trusted’ people who act as literacy/sociocultural brokers or ‘hot’ (familiar-informal) support of their grapevine of other students (past and present) or experienced community members.  相似文献
