BackgroundExtensive research has examined the relationship between exposure to family violence and its long-term mental health effects. Social support has been found to moderate this relationship, but there is a dearth of research on its mediating role.ObjectivesThe article presents the results of a study on the relationship between witnessing interparental violence and experiencing parental violence during childhood and adolescence on the one hand, and post-traumatic stress symptoms (PTSS) during young adulthood on the other. In addition, the article presents results on the role of social support as a mediator in this relationship.Method, participants, and settingA cross-sectional survey was conducted among 516 Israeli university and college students (90.7% female, and 9.3% male; M age = 24.9, SD = 2.7) using a retrospective, self-administered questionnaire.ResultsThe results revealed that exposure to each pattern of family violence (i.e., witnessing interparental violence and experiencing parental violence) predicted higher levels of PTSS. Furthermore, social support was found to partially mediate the relationship between exposure to family violence during childhood and adolescence and current PTSS as well as its four symptoms, i.e., depression, sleep disturbance, dissociation, and anxiety.ConclusionsThe results of the current study highlight the important role of social support in the association between adversities experienced early in life and young adulthood outcomes. The findings are interpreted on the basis of Conservation of Resources Theory (Hobfoll et al., 1990), which served as the conceptual framework for the study. The limitations of the study and implications for future research are discussed. 相似文献

BackgroundAdverse childhood experience (ACE) and intimate partner violence (IPV) have sustained, deleterious effects on physical and mental health. Few studies have examined how to help Latina survivors of ACEs and/or IPV regain control of their health.ObjectiveTo inform interventions for this population, we examined whether mastery of stress and patient activation mediate the relationship between a history of ACE and/or IPV and mental and physical health.Participants and settingWe recruited 235 Latina women (M age = 29.6, SD = 5.75) from primary care clinics.MethodFor this cross-sectional study, we used linear regressions to examine the association between ACEs, history of IPV, and health, and the sobel’s test to determine whether patient activation and mastery of stress mediated the relationships between ACEs, IPV, and health.ResultsMost women reported at least one ACE (61.7%, n = 137) and 22.2% (n = 55) reported a history of IPV. Mastery of stress mediated the relationship between ACE and physical health (b= -3.16 p = .002) and mental health (b= -3.83, p < .001). Mastery of stress also mediated the relationship between history of IPV and physical health (b= -2.62, p = .008) and mental health (b= -2.74, p = .006). Patient activation was not associated with a history of trauma or mental health.ConclusionWhile past experiences of trauma cannot be changed, results from this study suggest that improving an individual’s mastery of stress may be a point of intervention for improving mental and physical health among survivors of ACEs and IPV. 相似文献

BackgroundDespite global efforts to end violence against children in all settings, reports reveal that violence against children is still highly prevalent, especially in low-and middle- income countries. Violence in childhood is associated with a host of negative outcomes, and exposure in one setting can easily spill over to other contexts. For instance, exposure to family violence was not only related to mental health problems but also seems to be a risk factor for peer victimization.ObjectivesThe present study aimed to examine the prevalence of maltreatment within the family and adolescents’ mental health problems and their relation to peer victimization. We also aimed to gain new insights into the perceptions of adolescents concerning maltreatment within their families.MethodsData were collected from April to November 2017 in a representative sample of 702 students from 12 public secondary schools in Southwestern Uganda who responded to self-administered questionnaires.ResultsOverall, 95% of the students experienced at least one type of family violence in the past month. Students (81.3%) had endorsed some level of acceptance of violent discipline as a valid strategy in response to any misbehavior. Maltreatment within the family was related to peer victimization (β = .47) and this relation was mediated by mental health problems (0.002, 95%-CI: 0.001–0.004).ConclusionsThe results indicated a high prevalence of maltreatment within Ugandan families that was associated with peer victimization. This underscores the need to implement interventions aiming to reduce maltreatment and violence in order to protect children from potentially negative consequences. 相似文献

BackgroundToday, almost half of all refugees worldwide are children and adolescents, nearly a quarter of whom arrive in Europe as Unaccompanied Refugee Minors (URM). Many URMs have experienced the cumulative stress of being exposed both to the adverse environmental conditions which drive forced migration, and to the traumatic experience of displacement and resettlement. These experiences, coupled with other developmental stressors, may impede their overall development and increase their likelihood of mental health problems. Despite the evident vulnerability of URMs, much controversy currently surrounds the legitimacy of their arrival in host countries and their mental health is given little consideration.ObjectiveThis review synthesises and examines the limited published literature on the impact of traumatic refugee experiences on the mental health and development of URMs.MethodsAcademic databases and other sources were searched using key terms relating to URMs and mental health.ResultsThe findings confirm in large part that being a URM negatively influences mental health development, and that adolescence and being female are particular indicators of increased risk of psychiatric disorders. However, cultural differences in measurement and assessment of mental health are important confounding factors.ConclusionsThe current literature on youth in transit consistently paints a picture of how experiences URMs face can place a great burden on their mental health - clearly depicting an urgent need to consider their mental health within the current climate. The pressing need for improved care based on best practice is discussed. 相似文献

Recent research has shown that example study only (EE) and example-problem pairs (EP) were more effective (i.e., higher test performance) and efficient (i.e., attained with less effort invested in learning and/or test tasks) than problem-example pairs (PE) and problem solving only (PP). We conducted two experiments to investigate how different example and problem-solving sequences would affect motivational (i.e., self-efficacy, perceived competence, and topic interest) and cognitive (i.e., effectiveness and efficiency) aspects of learning. In Experiment 1, 124 technical students learned a mathematical task with the help of EEEE, EPEP, PEPE, or PPPP and then completed a posttest. Students in the EEEE Condition showed higher posttest performance, self-efficacy, and perceived competence, attained with less effort investment, than students in the EPEP and PPPP Condition. Surprisingly, there were no differences between the EPEP and PEPE Condition on any of the outcome measures. We hypothesized that, because the tasks were relevant for technical students, starting with a problem might not have negatively affected their motivation. Therefore, we replicated the experiment with a different sample of 81 teacher training students. Experiment 2 showed an efficiency benefit of EEEE over EPEP, PEPE, and PPPP. However, only EEEE resulted in greater posttest performance, self-efficacy, and perceived competence than PPPP. We again did not find any differences between the EPEP and PEPE Condition. These results suggest that, at least when short training phases are used, studying examples (only) is more preferable than problem solving only for learning. Moreover, this study showed that example study (only) also enhances motivational aspects of learning whereas problem solving only does not positively affect students’ motivation at all. 相似文献

失地农民进入城市会面临某些心理不适问题,具体表现在居住变化、经济压力、就业不足与保障不力等导致的心理不安、焦虑与抵触失衡心理,以及社会交往产生的封闭自卑心理、城市认同感欠缺与市民意识缺失等。心理不适问题的产生既与城市体制性因素以及城市居民的偏见与歧视有关,也与失地农民自身人力资本不足、农村传统文化的持续影响有关。应该从物质层面做好就业与保障工作、从社会文化层面扭转生活方式与价值观念以及从个体心理层面构建心理调适机制来实现失地农民心理适应。 相似文献

Background:Research on achievement goal orientations in sport has typically relied on the use of variable-centered approaches that tend to overlook population heterogeneity.In this study,we used a person-centered approach to identify subgroups of competitive tennis players according to unique combinations of achievement goal orientations and tested for subgroup differences in motivation and mental toughness.Methods:A sample of 323 competitive tennis athletes(69.35%male)between 15 and 25 years of age(17.60±2.40 years,mean±SD)completed the 3×2 Achievement Goal Questionnaire for Sport,Sport Motivation Scale Ⅱ,and Mental Toughness Index.Latent profile analysis was used to identify unique combinations of achievement goal orientations.Comparisons between latent subgroups on autonomous motivation,controlled motivation,and mental toughness were performed using analysis of variance.Results:Latent profile analysis supported 3 distinct patterns of achievement goal profiles that were primarily distinguishable based on valence of competence(i.e.,approach vs.avoidance).Analyses of variance indicated that athletes who were classified into subgroups that endorsed approach types of goals(regardless of the types of avoidance goals they endorsed)reported higher levels of autonomous motivation and mental toughness.Conclusion:Results indicated that athletes tend to pursue a number of achievement goals collectively rather than in isolation.Although approach goals are more commonly linked to adaptive psychological functioning and positive outcomes,avoidance goals may also be associated with desirable psychological characteristics if they are pursued in conjunction with approach types of achievement goals. 相似文献
