Three general classes of clinic-based programs to increase responsible sexual behavior are considered: (a) clinic-based educational/counseling programs, (b) school clinic-based condom distribution programs, and (c) clinic-based STD/HIV screening programs. Consistent condom use may double in response to clinic-based counseling. However, consistent use seldom exceeds 50% of coital exposures. Extensive and personalized counseling interventions reduce incident sexually transmitted infections by 5% to 10%. Increases in responsible sexual behavior following school-based condom distribution programs is reported in some but not in all studies. Screening programs for sexually transmitted infections are associated with decreases in rates of some infections. STD/HIV screening should be considered an important aspect of healthy sexuality and an adjunct to other counseling efforts. 相似文献

With rates of adolescent tobacco use steadily increasing over the past 20 years, assisting youth to quit, particularly those youth most susceptible to tobacco use, has become a national focus. The purpose of this pilot study was to examine and profile the smoking patterns of a small sample (n = 37) of juvenile offenders in Texas. In contrast to anecdotal reports, the sample group from this study did not differ clinically from the general population of adolescent tobacco users. Importantly, the study participants indicated previous attempts to stop smoking. The authors conclude that delinquent youth may be responsive to cognitive behavioral smoking cessation programs that also address the management of peer networks. 相似文献

Nonprofit agencies are struggling to meet new funder demands in outcome evaluation. This study is the first of its kind to examine factors that contribute to agency progress in this area. Path analysis is used to examine chains of influence among five predictors of success as well as three control variables. Study findings indicate that agency culture, technology, management support, and involvement are key predictors of quality. Nonprofit managers who want to succeed in the new era of accountability should consider the potential impact of these factors on the quality of outcome evaluation plans in their agencies. 相似文献

A new estimation method for the dimension of a regression at the outset of an analysis is proposed. A linear subspace spanned by projections of the regressor vector X , which contains part or all of the modelling information for the regression of a vector Y on X , and its dimension are estimated via the means of parametric inverse regression. Smooth parametric curves are fitted to the p inverse regressions via a multivariate linear model. No restrictions are placed on the distribution of the regressors. The estimate of the dimension of the regression is based on optimal estimation procedures. A simulation study shows the method to be more powerful than sliced inverse regression in some situations. 相似文献

The purpose of the present study was to understand, from parents' perspectives, the process of entry to community‐based services for children with developmental disabilities and to explore the relationship between patterns of entry and parent‐reported needs and priorities for service. Qualitative interviews were conducted with 43 mothers and 29 fathers of children with developmental disabilities approximately 6 months after the families entered community‐based childhood disability support services in Manitoba, Canada. Analysis of the coded interview data resulted in the identification of three process factors influential in the entry of families to community‐based support services: recognition of problems in child development, formal diagnosis of child disability and linkage between diagnostic services and the community‐based support system. Analysis of these processes identified four patterns of service entry associated with differing family needs for service: early entry, prompt entry, delayed entry and atypical entry. The results can be understood as a typology useful for social workers in the assessment of family needs and priorities at the point of entry to community‐based services. 相似文献

Research on end-of-life treatment preferences has documented robust racial differences, with African-Americans preferring more life-prolonging treatment than Whites. Although little research has attempted to explain these racial differences systematically, speculation has centered on religiosity. We examined a dimension of religiosity frequently invoked in end-of-life research-guidance by God's will-as a potential mediator of racial differences in such treatment preferences. Three hundred African-American and White men and women aged 60 or older participated in a 35-minute telephone interview that elicited preferences for four common life-prolonging treatments in each of nine health scenarios. The questionnaire included the five-item God's will (GW) scale, a health conditions checklist, a depression measure, and sociodemographic questions. GW mediated racial differences at least partially for most treatments and in most health scenarios. Implications are discussed for understanding end-of-life treatment preferences and why races tend to differ. 相似文献

Anal intercourse poses a greater risk for human immunodeficiency virus (HIV) transmission than vaginal intercourse, and in recent years there has been a growing understanding that heterosexual anal intercourse (HAI) is not uncommon. However, the majority of the anal intercourse literature has focused on men who have sex with men. The little research on HAI has mostly looked at women, with limited work among men. This analysis examined the association between HAI and high-risk behaviors (N = 1,622) and sexual sensation seeking (N = 239) in a sample of men recruited from 2001 to 2012 in Long Beach, California. Almost half of the sample was non-Hispanic Black. The median age was 42 years, 42% were homeless, and 20% reported recent HAI. Men who reported HAI were likely to be Hispanic, were likely to be homeless, had a male partner, engaged in sex exchange, and used cocaine or amphetamines during sex. Men who reported HAI scored higher on the Sexual Sensation Seeking scale. This research supports other work showing the relationship between HAI and high-risk behaviors. More important, it contributes new knowledge by demonstrating the association between HAI and sexual sensation seeking. This research highlights the importance of personality traits when trying to understand sexual behavior and when developing HIV prevention interventions. 相似文献

ABSTRACTOlder adults provide a long view of understanding environmental engagement from their early beginnings to their current community activities. This study draws on interviews with self-described environmentalists and follows a life course analysis that employs social work values and practice skills as they work towards environmental justice in their Midwestern communities. We conclude that the older adults of this second generation of environmentalists offer valuable lessons for social workers with regard to environmental justice, while at the same time contributing insights into older adult volunteering and addressing the challenge of a generational gap in participation in their community organizations. 相似文献
