College substance use policies provide guidelines for student behavior and influence campus culture. Although they are the primary environmental strategy to address campus substance use, policies have not been systematically compared and studied. We constructed a systematic review method to examine the accessibility, comprehensiveness, enforcement procedures, and clarity of college substance use policies. We developed an objective evaluation scheme for each of these 4 dimensions and then applied it to documented substance use policies from a sample of colleges and universities (N = 24). Policies were found to vary considerably but tended to specify compliance with local laws and emphasize student health and well-being. The next stage of campus policy review should examine actual implementation, evaluate potential differentiating factors among institutions, and assess the influence of policy on campus climate and student outcomes. 相似文献

This study examines how the social environment of religious congregations affects the spread of contraceptive use in developing contexts, using Mozambique as a case study. Analysis of qualitative data collected in urban areas of that country in 1998-99 and of the data from the 1997 Mozambique Demographic and Health Survey suggests that, in urban areas, the environment of more socioculturally diverse and inclusive Roman Catholic and mission-based Protestant congregations is more propitious to the spread and legitimization of modern contraception than the milieu of smaller, relatively homogeneous, independent churches. In rural areas, however, sociocultural diversity within and across different religious denominations is minimal, and membership in any formal congregation offers an advantage in contraceptive learning. 相似文献

Addiction severity predictions using client network properties 总被引:1,自引:0,他引:1

By statistical analysis of client data it is shown how past or current network information together with other knowledge assesses treatment needs. The main findings are as follows. The client's previous exposure to addicts in the family has almost no influence on his or her present contacts with addicts in daily life. About 30% of the clients have experienced addicts both in family and among friends, about 30% have only family exposure, about 20% have neither kind of exposure, and about 20% have no family exposure but have current exposure to addicts. Exposure to addicts in family implies a higher risk of severe need for professional intervention than no such exposure. For the clients with no family exposure but with current exposure to addicts there is, somewhat surprisingly, a lower risk than for the other three categories of clients. This effect seems to be mainly because the psychiatric status of these clients is somewhat better than for those in the other three categories. The effect disappears if we look solely for drug addiction intervention needs; then there is a clear increase in relative treatment needs for the categories with previous or present addiction exposure compared to those without. 相似文献

Despite the central role of women drug users in escalating AIDS statistics, there is still a limited number of studies that examine the roles of gender and drug use type in HIV seroprevalence. This lacuna in the research literature has led to significant gaps in researchers' understanding of how and to what extent women may differ in their drug-using and HIV risk behaviors compared to their better-studied male counterparts. This study, derived from a sample of 3,555 out-of-treatment drug users residing in three South Florida urban and rural communities, attempts to compare the drug usage and needle and sexual risk behaviors of male and female drug users that put them at risk for HIV infection. The overall seropositivity rate for women drug users was 26.5% compared to 19.5% for their male counterparts. Results of multivariate analyses indicate that females compared to males were 1.4 times more likely to be HIV seropositive. Risk behaviors associated with this elevated seropositivity include living arrangements, homeless status, drug use, sexual trading behaviors, and history of STDs. Furthermore, there was a strong linear relationship between drug use type and HIV seroprevalence among women drug users. Compared to those who were neither crack smokers nor injectors of illicit drugs, those who were crack smokers only were 2 times more likely to be HIV seropositive, while those who were both crack smokers and injectors were 5 times more likely to be HIV seropositive, and those who were injectors only were 6 times more likely to be HIV seropositive. These findings indicate that among women, drug abuse and its associated risk behaviors, increase the vulnerability of this population for HIV and thus render them an extremely important priority population on which to focus HIV prevention and public health efforts and programs. 相似文献

In this study, the authors investigated the characteristics of use, misuse, and abuse of stimulant medication (primarily methylphenidate and variants) among students at a northeastern US university. Researchers sent an invitation to take an Internet survey to student e-mail addresses and passed 150 paper surveys in undergraduate classes, analyzing 1,025 (975 electronically) returned surveys. Sixteen percent of respondents reported abusing or misusing stimulant medication. Ninety-six percent of respondents who specified a medication preferred to abuse or misuse Ritalin. Men and women reported similar use patterns. Most respondents who abused or misused stimulant medication swallowed pills; 40% used intranasally. Reasons for abusing or misusing stimulant medication included improving attention, partying, reducing hyperactivity, and improving grades. Consistent with previous studies, results suggest that abuse of stimulant medication is a concern on college campuses. The results point to various reasons for and methods of abusing and misusing stimulant medication that may direct future research, prevention, and intervention. 相似文献

SUMMARY This paper examines patterns of drug treatment entry and factors that are associated with these patterns among 1,849 Hispanic women injection drug users (IDUs). The data analyzed originates from a statewide drug-treatment database covering seven years, 1996–2002. Through the use of logistic regression analyses, the study identified significant differences in predisposing, need and enabling factors in the use of detoxification only, residential treatment, or methadone maintenance. Compared to other Hispanics, Puerto Rican women were 40 percent less likely to use only detoxification services and one and a half times more likely to use methadone maintenance. Having health insurance was an especially important factor associated with methadone treatment utilization. Two of the most important factors associated with residential treatment use were history of mental health services utilization and involvement with the criminal justice system. This article discusses specific social work practice implications including the need for social work practitioners to promote services such as residential treatment, to be trained in treatment of co-occurring mental health disorders, especially among women in residential treatment, and the need to establish close linkages with the mental health and criminal justice systems. 相似文献
