This study examined the measurement and invariance properties of the R-UCLA and de Jong Gierveld loneliness scales for research involving middle-aged and older adults. Confirmatory factor analyses (CFAs) of data from interviews with adults aged 45–84 revealed limited support for the unidimensionality of either scale while subsequent analyses indicated the multidimensionality of both. However, method effects associated with positive and negative item wording were also evident. Multiple group CFAs provided limited support for assumptions of measurement invariance across age groups and from baseline to follow-up with regard to the R-UCLA scale. In contrast, strong measurement invariance across age groups and successive measurements was established for the bi-dimensional dJG scale. Overall, the findings supported the relative utility of the dJG scale for research involving middle-aged and older adults but suggested a need for attention to the implications of method effects associated with item wording and lack of measurement invariance with respect to item residuals.  相似文献

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.  相似文献

This study compared the development of clinical assessment and intervention skills between students enrolled in a face-to-face (F2F) or an asynchronous online clinical social work class. All students from three semesters of F2F (n = 74) and online (n = 78) sections of an MSW clinical class taught by the same instructor were included. Two assignments were used to compare students: an assessment and treatment plan of a fictional case and a digital role-play. A doctoral student who was blinded to the course delivery mechanism graded the role-play. After controlling for baseline differences in age, there were no differences between online and F2F students in skill demonstration. It appears clinical skills can be taught as effectively online as in F2F situations based on blinded review of role-plays.  相似文献

Traditional definitions of farm work have been narrow and commodity-based, allowing the efforts of women to be discounted because they have not been viewed as directly contributing to production. This paper examines the structural gender arrangements that operate to render farm women powerless and to discount their contributions. Data are presented on the extent of women's economic contribution on Australian farms.  相似文献

In Africa and elsewhere, educated women tend to marry later than their less-educated peers. Beyond being an attribute of individual women, education is also an aggregate phenomenon: the social meaning of a woman’s educational attainment depends on the educational attainments of her age-mates. Using data from 30 countries and 246 birth cohorts across sub-Saharan Africa, we investigate the impact of educational context (the percentage of women in a country cohort who ever attended school) on the relationship between a woman’s educational attainment and her marital timing. In contexts where access to education is prevalent, the marital timing of uneducated and highly educated women is more similar than in contexts where attending school is limited to a privileged minority. This across-country convergence is driven by uneducated women marrying later in high-education contexts, especially through lower rates of very early marriages. However, within countries over time, the marital ages of women from different educational groups tend to diverge as educational access expands. This within-country divergence is most often driven by later marriage among highly educated women, although divergence in some countries is driven by earlier marriage among women who never attended school.  相似文献

Few studies have examined male clients who pay for sex with male escorts. In 2012, clients (n = 495) completed an online survey about their most recent hire. Most clients were White/Caucasian (87.7%), HIV negative (89.5%), employed full time (71.1%), single (58.6%), with a mean age of 54. Three-quarters of clients were gay identified, 18% bisexual, and 4% heterosexual. The median rate paid to escorts was $250 per hour with a modal appointment time of 1 to 2 hours (41.6%). Oral sex was common (80% gave, 69% received), 30% reported anal insertive sex, and 34% reported anal receptive sex. In total, few (12%) reported unprotected anal sex. Satisfaction with encounters was high. Receptive unprotected anal intercourse was associated with greater satisfaction in bivariate analyses but not in multivariable analyses. In a multivariable model, having receptive anal sex (whether protected or not) and rating the financial cost of the encounter as “worth it” were significantly associated with greater satisfaction. This study contributes to a scarce literature regarding clients of male sex workers and, in particular, provides information on the characteristics of men hiring men for sexual services, behavioral event-level data about their encounters, and analysis of factors directly associated with client satisfaction.  相似文献

Lesbian, gay, and bisexual (LGB) youths are over-represented in the homeless population. To examine why some LGB youths become homeless, this report compares homeless and non-homeless LGB youths. Of the 156 LGB youths, 48% reported ever being homeless (i.e., running away or being evicted from home). Results indicate that sexual orientation awareness and the initiation of sexual behavior occurred earlier in homeless than in non-homeless LGB youths and predated the first homeless episode. Substance use was more frequent and first occurred at an earlier age in homeless as compared to non-homeless LGB youths; however, substance use occurred subsequent to first homelessness. Childhood sexual abuse was associated with homelessness; and, early sexual orientation development was related to homelessness among youths without a history of sexual abuse. Findings suggest that interventions should help youths cope with their unfolding sexual orientation and work to prevent or address the consequences of sexual abuse.  相似文献
