The Natsal-SF is a psychometrically validated measure of sexual function for use in community health surveys, derived from 17 questions reflecting three components of sexual function. Scoring requires knowledge of complex statistical modeling and, given the methodological complexities, we assessed the validity of two simplified scoring methods calculated using the factor loadings produced when originally modeling the Natsal-SF items. Method 1 uses these factor loadings to three decimal places, while method 2 assigns whole numbers to each item based on the factor loadings. Scores from these simplified methods are compared to the original score using correlation coefficients, by comparing the distributions and the scores of each method in a linear regression model with key variables. We found scores from the simplified methods both correlate highly with the original score, and the distributions of scores closely match. The simplified methods result in different regression coefficients for gender and relationship context but estimate the coefficients of all other variables similarly to the original method. While the Natsal-SF should ideally be scored using latent variable modeling, the simplified methods perform well so can be used in similar contexts, increasing the utility of the Natsal-SF and enabling future studies to measure sexual function more comprehensively. 相似文献

This article uses administrative data on all active employees of the Federal Reserve (FR) System to examine participation in and contributions to the Thrift Saving Plan, the System's defined contribution (DC) plan. We link to administrative records a unique employee survey of economic/demographic factors including a set of financial literacy questions. Not surprisingly, FR employees are substantially more financially literate than the population at large. Most importantly, financially savvy employees are also most likely to participate in their DC plan. Sophisticated workers contribute three percentage points more of their earnings to the DC plan than do the less knowledgeable, and they hold more equity in their pension accounts. We examine changes in employee plan behavior 1 year after employees completed a Learning Module about retirement planning, and we compare it to baseline patterns. We find that those employees who completed the Learning Module were more likely to start contributing and less likely to have stopped contributing to the DC plan postsurvey. In sum, employer‐provided learning programs are shown to significantly impact employee retirement saving decisions and consistent with a lot of other research, higher levels of financial literacy are found to have a beneficial impact on retirement saving patterns.

As interventions based on practice guidelines spread within social work practice, educators must determine how, if at all, these guidelines may be incorporated into the curriculum of undergraduate and graduate social work education. This article provides an overview of the history and the debate surrounding practice guidelines and identifies key considerations that must be addressed in order for faculty to make a rational and deliberate decision regarding the inclusion of practice guidelines within the curriculum. 相似文献

A grassroots social service organization's successful use of Afrocentric ideas, theories, and frameworks in its programs and services illustrates that many African Americans respond more readily to human and social services interventions that value and understand their historical experiences and include their cultural influences as “protective factors” in social service interventions. This article describes how the Community Empowerment Association's programs and services are designed to be culturally proficient by holding African customs, ethos, history, mores, society, and traditions in high esteem. 相似文献

Background.?Saliva collection is an easy, non-invasive method to measure hormones.Methods.?Two studies were performed. In the first, a convenience sample of 1454 males who had submitted saliva for salivary testosterone measurements were studied. In the second study, we intensively studied symptoms and measurements of total testosterone, free testosterone symptoms and measurements of total testosterone, free testosterone and bioavailable testosterone in relationship to salivary testosterone in 127 men. A secondary endpoint was to examine the relationship of salivary testosterone to hypogonadal symptoms in the ADAM and AMS questionnaires.Results.?In the first study, we have shown that salivary testosterone, measured in 1454 males aged 20 to 89 years, declines by 47% over the lifespan. In the second study, salivary testosterone was strongly correlated with bioavailable testosterone (p < 0.000001) calculated free testosterone (p < 0.00001) and total testosterone (p < 0.002). Salivary testosterone was significantly related to hypogonadal symptoms on the St. Louis University ADAM questionnaire and the Aging Male Survey.Conclusions.?These studies support the use of salivary testosterone as an acceptable assay for screening for hypogonadism. Salivary testosterone is not a better assay than other measures to diagnose hypogonadism. 相似文献

We evaluated how ambitions, community ties, monetary sufficiency, employment, and alcohol consumption related to whether young American Indian adults had moved from their Northern Plains reservation. Of 518 Northern Plains reservation residents in 1993, we located 472 in 2003–2005 and found that 89 lived more than a four-hour drive from the reservation. Coding the 472 as to whether they had stayed on/near the reservation or moved away, we ran logistic regressions on data they reported in 1996 to determine which demographic and attitudinal variables were associated with having moved. We found ambitions and goals were more associated with moving away than were ties to the community, which in turn were more related than monetary and personal characteristics that promote independence and prosperity. The more importance they placed on getting a good education or carrying on the tribe’s traditions, the more likely they were to have moved away. We found too that the odds of moving away decreased with greater alcohol consumption. Tribal council members and college administrators therefore may wish to promote policies that increase opportunities for young adults to achieve higher education goals while remaining on reservation to carry on tribal traditions. Benefits may also come from encouraging and assisting reservation members studying off-reservation to return after completing their education. These findings would argue too for greater investment in alcohol services for reservation-dwelling populations. 相似文献
