Research on the influence of volunteering on mental health outcomes has not placed enough focus on African American female caregivers who are at risk for adverse outcomes such as depression. This study addresses this gap by examining the mechanism through which volunteering might influence depressive symptoms using data collected from 521 African American female caregivers of older adults. Regression results indicate that although volunteering is inversely associated with depressive symptoms, self-esteem mediates this relationship. Findings suggest inclusion in volunteering for African American female caregivers may be relevant to promotion of their mental well-being. 相似文献

The purpose of this study was to inform future Public Service Announcement (PSA) development by examining the potential effectiveness of different types of anti-driving under the influence (DUI) PSAs for persons with different characteristics. PSAs utilizing empathy, fear, and informational approaches were shown to persons recruited from psychology courses (n = 137) and individuals that were mandated to treatment following a DUI offense (n = 17). The empathy approach was perceived to be the most effective and evoked the most negative affect, followed by fear and informational approaches. Less experience with DUI, lower sensation seeking, higher motivation to change, and higher perception of dangerousness of DUI all emerged as good predictors of higher perceived effectiveness of anti-DUI PSAs. Gender differences in perceived effectiveness were examined for fear and empathy PSAs, with inconclusive findings. 相似文献

OBJECTIVE: The objective of this study was to examine connections between university students' mental health and their knowledge and use of campus mental health services. PARTICIPANTS AND METHODS: In March 2001, a sample of undergraduate students (N = 266) completed a Web-based questionnaire, providing information related to their mental health, knowledge of mental health services, and use of those services. RESULTS: Students who were mentally distressed were more likely to know about and use services; however, some students who reported to be mentally distressed either did not know about services or knew about services but did not use them. Living off campus, identifying as male, and having fewer years in college were related to less knowledge of campus mental health services. In addition, female sex and number of years in college were predictive of higher service use. CONCLUSIONS: With the high prevalence rates and severity of mental health problems, university mental health providers must continue to make strategic efforts to disseminate knowledge about mental health services to all students. 相似文献

The current study examines leadership in the context of the 2008 presidential election. Longitudinal data were collected across three regions of the United States to yield 414 responses. Perceptions of crisis were positively related to attributed charisma but not perceptions of authentic leadership. Value congruence moderated the relationship between cynicism and attributed charisma for Obama (but not for McCain) and between cynicism and perceptions of authentic leadership for McCain (but not for Obama). Attributed charisma was found to have augmenting effects over authenticity in predicting voting behavior. The contributions made to the charismatic, authentic, and crisis leadership literatures are discussed and directions for future research presented. 相似文献

A lethal defect-wear model of mortality is presented which rationalizes the assumption of independent risks when death may be due to more than a single condition, Under this model, it is shown how competing risk theory and standard categorical data methods may be merged in a unified approach to the analysis of multiple-cause mortality data. The methodology is used to analyze linkages among diseases in the mortality data and evaluate the implication of the elimination of patterns of morbid states for multiple-cause mortality data from deaths occurring in 1969 in North Carolina. 相似文献

To influence the number of children ever born to a woman, socioeconomic variables must operate through behavioral and biological mechanisms such as the age at marriage, the level of fertility in the absence of deliberate fertility control, and the level of control exerted to reduce fertility within marriage. In this paper, we propose a new measure of cumulative fertility which is standardized for the age-fecundity relationship and for exposure to the risk of conception associated with duration of marriage. A simple model of fertility behavior which incorporates some of the mechanisms through which socioeconomic factors may affect fertility is developed and applied to data from the United States to demonstrate the properties of alternative measures of family size. The results indicate that use of the new measure allows more precise estimates of socioeconomic fertility relationships than would be obtained with children ever born or by sample stratification. 相似文献

This study explores the association between female circumcision and infertility and fertility, using information from the Demographic and Health Surveys (DHS). In Côte d’Ivoire and Tanzania, circumcised women had lower childlessness, lower infertility by age, and higher total fertility rates than women who were not circumcised; the reverse pattern prevailed in the Central African Republic. In all three countries, however, circumcised women grouped by age at circumcision did not have significantly different odds of infertility nor of having a child than did uncircumcised women, when the effects of covariates were controlled. Thus we find evidence suggesting that the practice of female circumcision does not have a statistically discernible effect on women’s ability to reproduce. 相似文献

On the basis of research on paired Muslim and non‐Muslim communities selected in India, Malaysia, Thailand, and the Philippines, the authors test the hypothesis that greater observed Muslim pronatalism can be explained by less power or lower autonomy among Muslim women. Indeed, wives in the Muslim communities, compared to the non‐Muslim ones: 1) had more children, 2) were more likely to desire additional children, and 3) if they desired no more children, were less likely to be using contraception. However, the authors do not find that Muslim communities consistently score lower on dimensions of women's power/autonomy. Thus, aggregate‐level comparisons provide little evidence of a relationship between lower autonomy and higher fertility. Individual‐level multivariate analysis of married women in these paired settings similarly suggests that women's autonomy differentials do not account for the higher fertility, demand for more children, and less use of contraception among Muslim wives. These results suggest that explanations for Muslim/non‐Muslim fertility differences lie elsewhere. 相似文献
