This study examined reciprocal support networks involving extended family, friends and church members among African Americans. Our analysis examined specific patterns of reciprocal support (i.e., received only, gave only, both gave and received, neither gave or received), as well as network characteristics (i.e., contact and subjective closeness) as correlates of reciprocal support. The analysis is based on the African American subsample of the National Survey of American Life. Overall, our findings indicate that African Americans are very involved in reciprocal support networks with their extended family, friends and church members. Respondents were most extensively involved in reciprocal supports with extended family members, followed closely by friends and church networks. Network characteristics (i.e., contact and subjective closeness) were significantly and consistently associated with involvement with reciprocal support exchanges for all three networks. These and other findings are discussed in detail. This study complements previous work on the complementary roles of family, friend and congregational support networks, as well as studies of racial differences in informal support networks.  相似文献

The gender paradox in mortality--where men die earlier than women despite having more socioeconomic resources--may be partly explained by men's lower levels of preventive health care. Stereotypical notions of masculinity reduce preventive health care; however, the relationship between masculinity, socioeconomic status (SES), and preventive health care is unknown. Using the Wisconsin Longitudinal Study, the authors conduct a population-based assessment of masculinity beliefs and preventive health care, including whether these relationships vary by SES. The results show that men with strong masculinity beliefs are half as likely as men with more moderate masculinity beliefs to receive preventive care. Furthermore, in contrast to the well-established SES gradient in health, men with strong masculinity beliefs do not benefit from higher education and their probability of obtaining preventive health care decreases as their occupational status, wealth, and/or income increases. Masculinity may be a partial explanation for the paradox of men's lower life expectancy, despite their higher SES.  相似文献

Introduction The Aging Male Symptoms' (AMS) scale was designed as a health-related quality of life (QoL) scale and standardized as a self-administered scale, first, to assess symptoms of aging (independent from those which are disease-related) between groups of males under different conditions, second, to evaluate the severity of symptoms/QoL over time, and, third, to measure changes pre- and post-androgen replacement therapy. The scale is in widespread use (17 languages currently available) and a recent review of methodological data documented good psychometric characteristics and ability as a clinical utility. This paper describes test characteristics of the AMS (positive and negative predictive values), taking two internationally established and published screening scales for androgen deficiency as the available standard.

Method A sample of 150 German males aged 40–69 years completed the AMS scale and two screening scales for androgen deficiency: the ADAM scale of Morley and colleagues and the screener of Smith and colleagues. The technique of a computer-assisted telephone interview was applied.

Result The comparison of the AMS with the two screening instruments for androgen deficiency showed sufficiently good compatibility despite conceptual differences. The AMS scale sufficiently predicted the results of the two screening instruments. A positive predictive value of 92% and a negative predictive value of 50% were found regarding the ADAM scale. The respective figures regarding Smith's screener were 65% and 49% for positive and negative predictive values, respectively.

Conclusion The AMS scale obviously measures a similar phenomenon as the two established and widely used screeners for androgen deficiency, although it was not developed as a screening instrument.  相似文献

Biomedical research consistently finds that Blacks have worse physical health than Whites, an expected pattern given Blacks' greater exposure to psychosocial stress, poverty, and discrimination. Yet there is surprising lack of consensus regarding race differences in mental health, with most scholars finding similar or better mental health outcomes among Blacks than Whites. Past research often attributes this “race paradox in mental health” to the notion that Blacks have stronger family networks than Whites, yet few studies have explicitly tested whether stronger family relationships among Blacks (if they exist) can account for these findings. Using data from the 2003–2005 National Survey of American Life (N = 4,259) revealed that minimal race differences in family relationships fail to explain the race paradox in mental health. The results have implications for mental health measurement, the provision of culturally appropriate mental health care, and how scholars understand the nature of family relationships among Black Americans.  相似文献

What's an Oscar worth?   总被引:9,自引:0,他引:9  
This article examines the impact of an Academy Award nomination and award for best picture, best actor/actress, and best supporting actor/actress on a film's (i) market share of theaters, (ii) average revenue per screen, and (iii) its probability of survival. The model is estimated using weekly box-office data for a matched sample of nominated and non-nominated films. The results indicate substantial financial benefits for a nomination and award for best picture and best actor/actress. The structure of rewards is consistent with that found in two-stage, single-elimination tournaments.  相似文献

ABSTRACT

Past research has identified a link between discrimination and health outcomes among people of color. Perceptions of the cause of discrimination (racial versus other) seem to be important for mental health; however, this relationship has not been fully examined for physical health. Using data from the National Survey of American Life, we find that, among African-Americans, racial discrimination and overall discrimination regardless of attribution are associated with negative health outcomes while non-racial discrimination is not. The results suggest that racial discrimination has a unique adverse effect on physical health for African-Americans that practitioners need to better understand.  相似文献
