Objective: Pain affects a significant proportion of college students in the United States and has been linked to anxiety and depressive symptoms. Rumination and worry, two transdiagnostic factors linked to comorbidity, may explain the relationship between pain and mental health symptoms.

Current Study: The current study examined worry and rumination as explanatory factors in the relationship between pain and anxiety and depressive symptoms in a sample of college students with pain (n?=?1,577; 79.9% female).

Results: Results indicated that both rumination and worry explained the relationship between pain and depressive and social anxiety symptoms, while rumination alone explained the relationship between pain and anxious arousal symptoms.

Conclusion: The current study provides novel empirical evidence that worry and rumination each help explain the relationship between pain and anxiety and depressive symptoms among college students with current pain, and college students in pain may benefit from targeted psychosocial strategies aimed at decreasing worry and ruminative responses.  相似文献

This article explores the migrant networks that develop between migrants, non‐migrants and the larger Indian diaspora. Specifically, it examines the decision to migrate to Toronto, Canada and how this decision is shaped by, and in turn shapes the migrant network. Based on 35 interviews with migrants from Karnataka, South India, two main findings are presented. First, migrants are deliberately choosing settlement countries in which their families are not yet located, thereby becoming “migrant pioneers” in their country of settlement, which is an attempt to expand their migrant networks globally. Second, the narratives these migrants receive and subsequently impart to others are often inaccurate, which can lead to miscommunication flows among these migrant networks. These findings are considered in light of the large body of research on migrant networks and the ways they develop and transmit information. This paper argues that existing understanding of migrant networks is somewhat static. Findings indicate that these “migrant pioneers” may be engaging in global risk‐diversification strategies for subsequent generations, but may themselves suffer from the more immediate consequences of misinformed networks.  相似文献

Early investigations of the effects of non-normality indicated that skewness has a greater effect on the distribution of t-statistic than does kurtosis. When the distribution is skewed, the actual p-values can be larger than the values calculated from the t-tables. Transformation of data to normality has shown good results in the case of univariate t-test. In order to reduce the effect of skewness of the distribution on normal-based t-test, one can transform the data and perform the t-test on the transformed scale. This method is not only a remedy for satisfying the distributional assumption, but it also turns out that one can achieve greater efficiency of the test. We investigate the efficiency of tests after a Box-Cox transformation. In particular, we consider the one sample test of location and study the gains in efficiency for one-sample t-test following a Box-Cox transformation. Under some conditions, we prove that the asymptotic relative efficiency of transformed t-test and Hotelling's T 2-test of multivariate location with respect to the same statistic based on untransformed data is at least one.  相似文献

The cross-national measurement invariance of the teacher and classmate support scale was assessed in a study of 23202 Grade 8 and 10 students from Austria, Canada, England, Lithuania, Norway, Poland, and Slovenia, participating in the Health Behaviour in School-aged Children (HBSC) 2001/2002 study. A multi-group means and covariance analysis supported configural and metric invariance across countries, but not full scalar equivalence. The composite reliability was adequate and highly consistent across countries. In all seven countries, teacher support showed stronger associations with school satisfaction than did classmate support, with the results being highly consistent across countries. The results indicate that the teacher and classmate support scale may be used in cross-cultural studies that focus on relationships between teacher and classmate support and other constructs. However, the lack of scalar equivalence indicates that direct comparison of the levels support across countries might not be warranted.  相似文献

We liaised with a wharekura (Māori language immersion school) to translate and disseminate an online survey for a group of Māori youth in Southland, New Zealand (NZ). The focus of this article is not results, but the processes of respondent orientation and engagement to more genuinely include Māori in a youth survey. An online survey about transport and well-being was conducted with older teenagers from 12 schools, including the wharekura. After working with wharekura staff and students, the survey was translated from English into te reo Māori using best-practice methods. Steps were taken to safeguard authentic engagement, including how the survey translation was conducted, and how the survey data were shared. This NZ-specific experience adds to the literature about the practice of applying the principle of respondent orientation to the process of translating an existing survey into te reo Māori, demonstrating commitment to some Treaty of Waitangi principles. While this is not a kaupapa Māori research project, it is informed by some kaupapa Māori principles. This may be seen as a limitation of this work; however, we believe there are many positive experiences and lessons to be learned from our approach.  相似文献

DO RACE AND ETHNICITY MATTER AMONG FRIENDS?   总被引:4,自引:0,他引:4  
Using the National Longitudinal Study of Adolescent Health (or Add Health), a nationally representative sample of adolescents in 1994–1995, we examine if and how friendship activities differ among interracial, interethnic, and interethnic friendships of white, black, Hispanic, and Asian youths. We find that best friends are more likely than higher-order friends to be from the same ethnic group and that best friends report more shared activities during the past week than do their higher-order friendship counterparts. Hence, we argue that shared activities is a useful indicator of friendship intimacy. In general, interracial friends report fewer shared activities than do intraracial friends, although this difference is strongest for white respondents. Moreover, we find that white, Asian, and Hispanic youths all report fewer activities with their black friends. We find little difference in friendship activities between interethnic and intraethnic friendships. Our findings suggest that, even when youths manage to break racial boundaries in friendship selection, these friendships face greater challenges than do those between individuals of the same race.  相似文献

Community-recruited women (n = 1490) were interviewed about their early and adult sexual victimization histories to determine whether there was an association between child sexual abuse and adult revictimization by sex partners and strangers/nonsex partners. Adolescent sexual abuse, lifetime sex-trading, drug treatment, and mental health treatment were examined as mediating variables. One-fourth of the women had been revictimized (i.e., experienced child sexual abuse and at least one instance of adult sexual victimization). Child sexual abuse was associated with both rape and other sexual victimization by a sex partner in adulthood, as well as adult rape by a stranger/nonsex partner. Drug and mental health treatments reduced abused women's chances of being raped by a sex partner; drug treatment also decreased the likelihood of other sexual victimization by a sex partner. Sex-trading increased abused women's likelihood of rape by a stranger or nonsex partner. Intervention--including drug treatment--can help women with child sexual abuse histories overcome some of the abuse-related sequelae that make them vulnerable to adult revictimization.  相似文献

As the US workforce continues to age, organized labor and management will have to work creatively to redesign jobs, workflow, and work pace to accommodate older workers. Union-management cooperation in developing safety strategies have been largely unsuccessful because of mutual distrust, animosity left over from contract negotiations and administration, the absence of strong labor legislation that promotes shared governance, injury concealment, and world-wide competitive pressures to reduce labor costs at the expense of worker safety. If workplace injury prevention that focuses on cost-effective and efficient workplace modifications for older as well as for all workers is to become reality, then employers and their unions will need to develop solutions to forge new, more expansive approaches to accommodation.  相似文献
