This study was designed to systematically compare and contrast the psychometric properties of three scales developed to measure sexual satisfaction and a single-item measure of sexual satisfaction. The Index of Sexual Satisfaction (ISS), Global Measure of Sexual Satisfaction (GMSEX), and the New Sexual Satisfaction Scale–Short (NSSS-S) were compared to one another and to a single-item measure of sexual satisfaction. Conceptualization of the constructs, distribution of scores, internal consistency, convergent validity, test-retest reliability, and factor structure were compared between the measures. A total of 211 men and 214 women completed the scales and a measure of relationship satisfaction, with 33% (n = 139) of the sample reassessed two months later. All scales demonstrated appropriate distribution of scores and adequate internal consistency. The GMSEX, NSSS-S, and the single-item measure demonstrated convergent validity. Test-retest reliability was demonstrated by the ISS, GMSEX, and NSSS-S, but not the single-item measure. Taken together, the GMSEX received the strongest psychometric support in this sample for a unidimensional measure of sexual satisfaction and the NSSS-S received the strongest psychometric support in this sample for a bidimensional measure of sexual satisfaction.  相似文献

Family formation changed dramatically over the 20th century in the United States. The impact of these changes on childbearing has primarily been studied in terms of nonmarital fertility. However, changes in family formation behavior also have implications for fertility within marriage. The authors used data from 10 fertility surveys to describe changes in the timing of marital childbearing from the 1940s through the 21st century for non‐Hispanic White and non‐Hispanic Black women. Based on harmonized data from the Integrated Fertility Survey Series, the results suggest increasing divergence in fertility timing for White women. A growing proportion of marriages begin with a premarital conception; at the same time, an increasing proportion of White women are postponing fertility within marriage. For Black women, marital fertility is increasingly postponed beyond the early years of marriage. Evaluating the sequencing of marriage and parenthood over time is critical to understanding the changing meaning of marriage.  相似文献

The Pacific Sociological Association annual meeting recently added a new session type called the Research-in-Progress (RIP) session. The purpose of adding these sessions was to provide an opportunity for attendees to present research still in formative stages of completion in order to get useful feedback. Presentations ranged from doctoral dissertation proposals to nearly completed research. Early experience from RIP session organizers and discussants is that these sessions were lively and engaging, sparking a great deal of audience participation. Feedback from presenters indicated that they received useful feedback. Based on our initial experience with the RIP sessions, we believe they are a beneficial addition to the meetings.  相似文献

Demographic disparities between the rates of occurrence of an adverse economic outcome can be observed to be increasing even as general social improvements supposedly lead towards the elimination of the adverse outcome in question. Scanlan (Chance 19(2):47–51, 2006) noticed this tendency and developed a ‘heuristic rule’ to explain it. In this paper, we explore the issue analytically, providing a criterion from stochastic ordering theory under which one of two demographic groups can be considered disadvantaged and the other advantaged, and showing that Scanlan’s heuristic obtains as a rigorous finding in such cases. Normative implications and appropriate social policy are discussed.  相似文献

In dominant theories of criminal desistance, marital relationship formation is understood to be a key “turning point” away from deviant behavior. Empirical studies supporting this claim have largely focused on the positive role of marriage in men's desistance from crime, and relatively few studies have examined the role that nonmarital relationships may play in desistance. Drawing on 138 longitudinal in‐depth interviews with 22 men and women reentering society from prison, this article extends the scope of desistance research by additionally considering the significance of more fleeting and fluid relationships, and the diverse processes through which romantic relationships of all sorts are linked with criminal behaviors. We present an empirically based typology detailing six processes, grouped within three conceptual categories, through which romantic relationships had their effects. These pathways include material circumstances, social bonds and interactions, and emotional supports and stressors. We also consider gender differences in these processes. While more tenuous bonds to marginally conventional partners would seem to exert little effect, as one of the few relationships and social roles available to many former prisoners, we found that they wielded important influence, if not always in a positive direction.  相似文献

The relationship between HIV/AIDS and gay activism has been primarily informed by the American experience and understudied in nondemocratic contexts. Drawing upon qualitative research on China and Singapore, we refine understanding of HIV/AIDS’ influence on the development of gay activism under authoritarian conditions, by examining the processes through which activist organizations interact with laws and regulations, political norms, HIV/AIDS funding, and government responses to both HIV/AIDS and collective organizing. We show how HIV/AIDS’ influence plays out in multiple patterns, depending on the strategic responses that gay activists select from a constrained range of options to shape their organizations’ destinies. Therefore, we provide insights for development agencies and international donors into whether and how international assistance intended to encourage activism and wider social change are mediated by political and legal controls on local activism.  相似文献

Growth and internationalisation of the Chinese economy have reconfigured the global value chains of many commodities with important implications for industry and rural and regional development both in and outside China. This article analyses the chain for cashmere, all stages of which have gravitated to China, and the impacts on rural development, especially for herders in remote pastoral regions. Traditionally a high‐value product, cashmere has become increasingly generic and adulterated over the past decade. More formal and closer integration of Chinese actors into the global industry and re‐orienting policy from supply‐side intervention to the enforcement of standards would enhance the competitiveness of Chinese cashmere in international fibre markets.  相似文献
