In recent decades, a norm of tolerating group differences has been promoted by laypeople and leaders as a way to manage cultural and religious diversity. But whether such a policy is beneficial for the targets’ sense of group belonging and well-being is unknown. This research investigates how being tolerated differs from being discriminated against and being accepted in its associations with affective well-being and ethnic and national identification of ethnic minorities. We test whether being tolerated is related to well-being through its association with both group identifications. With a sample of ethnic minority group members in the Netherlands (N = 518) we found that being tolerated is related to higher well-being through increased national identification, but not as strongly as being accepted. Being tolerated is different from experiencing discrimination against and being accepted, and its relations to well-being and group belonging often fall between those of discrimination and acceptance. Toleration is associated with higher well-being, but only to the extent that its targets feel included in the overarching national category. 相似文献

“体教结合”是解决当前我国竞技体育发展问题的重要途径和举措。传统的体育后备人才培养模式只重视专项体育技能的发展而忽视了文化教育的重要性,不利于个体的全面发展。“体教结合”更重视人的全面发展,体育与教育的融合,使得竞技体育人才逐渐从运动员这一单一角色向“学生-运动员”双重角色转变。研究以角色认同为切入口,探讨上海“体教结合”举措下,角色的转变对体育竞技后备人才的影响。选取上海体育学院中国乒乓球学院少年班学员作为“学生-运动员”样本,选取国家乒乓球青年队及部分省市队队员作为职业运动员样本,使用结构化心理测量工具,对比两类受访者在运动与学业上的角色认同、心理倦怠与动机变量的差异。得出:在上海“体教结合”举措下,竞技体育后备人才认同“学生-运动员”双重角色,他们在学业任务中的卷入程度更高;双重角色使运动员在运动任务与学业任务上的主观价值感存在差异,表现出双重角色之间的冲突,但对个体的整体人生规划并不冲突;双重角色之间的转化,对于“学生-运动员”的心理健康存在促进效应。 相似文献

A voluminous literature exists on the relationship between team identification and various consumer thoughts, attitudes, and behaviours. However, the psychological meaning of team to consumers remains unknown, as scholars have studied individuals’ identification with a team without empirically investigating its meaning. Following an interpretive mode of inquiry in this study, the authors used interviews and concept mapping to understand the meaning of team among fans of two separate teams. An important discovery is that the meaning of team evolves due to environmental changes and personal experiences. At the same time, the authors determined that the meaning of team in team identification has three broad components: place, past, and present, each of which uniquely contributes to the identity. The authors conclude by discussing the implications of this research on the team identification literature and offering suggestions to practitioners and researchers. 相似文献

Relying on data from a nationally representative sample of youth involved in the child welfare system (CWS) in 1999–2000 (the National Survey of Child and Adolescent Well-Being, Cohort 1) and 2008–2009 (Cohort 2), this study implemented a diverse set of disparity indicators to estimate area-socioeconomic disparities in mental health (MH) services use and changes in area-socioeconomic disparities between the two cohorts. Our study found that there are area-socioeconomic disparities in MH service use, indicating that the rates of MH service use among youth referred to the CWS differ by area-socioeconomic positions defined by county-level poverty rates. We also found that area-socioeconomic disparities increased over time. However, the magnitude of the increase varied widely across disparity measures, suggesting that there are different conclusions about the trend and magnitude of area-socioeconomic disparities, depending upon which disparity measures are implemented. A greater understanding of the methodological differences among disparity measures is warranted, which will in turn impact how interventions are designed to reduce socioeconomic disparities among children in the CWS. 相似文献

Child maltreatment is a risk factor for detrimental effects on mental health that may extend to adulthood. This study aimed to examine the association between exposure to childhood maltreatment, socio-demographic factors, and students’ mental health status and self-esteem. A cross-sectional study enrolled a representative sample of 1270 students from Kuwait University. An anonymous self-administered questionnaire included students’ socio-demographic characteristics, history of exposure to childhood physical and/or emotional maltreatment, DASS-21 to assess mental health status, and Rosenberg self-esteem scale was used. Chi-square test and binary logistic regression models were applied. The study found that among participants, 49.6%(95% CI: 64.8%–52.4%), 63.0%(95% CI: 60.3%–65.7%), and 43.8%(95% CI: 41.1%–46.6%) reported having depression, anxiety, and stress respectively. Moreover, 22.5%(95% CI: 20.1%–24.8%) and 18.6%(95% CI:16.5%–20.9%) reported childhood physical and emotional maltreatment, respectively; while 12.7% reported both. Multivariate analysis revealed that experiencing childhood physical and emotional maltreatment were independent contributors to reporting depression and anxiety; while exposure to only emotional maltreatment contributed to reporting stress. Gender, GPA, childhood enrollment in private/public schools, number of close friends, were other contributors to mental health problems. Participants’ median score of self-esteem was 17/30, and only childhood emotional maltreatment was a significant predictor to low self-esteem after adjustment for other confounders. Mental health problems, and experiencing childhood physical and emotional maltreatment were prevalent relatively high among university students. Childhood corporal and emotional maltreatment were independent predictors to adolescents and young adults’ mental health problems. Experiencing childhood emotional maltreatment predicted low self-esteem. Further research to assess culture factors associated with childhood maltreatment is recommended. 相似文献
