SOME DEMOGRAPHIC CORRELATES OF HIV/AIDS-RELATED DISCRIMINATION

In late 1991, a survey was made of HIV/AIDS-related discrimination in the Australian community. Structured telephone interviews were conducted with a random sample of 2,053 respondents. Twenty-one questions provided an index of expressed discrimination. Social contact with HIV-positive people was a significant predictor of low levels of discrimination. Other important predictors of (lower) levels of discrimination were: social contact with gay men, education, sex, age, sexual identity, and sexual experience. Social contact with gay men was the single best predictor of positive attitudes towards people with HIV/AIDS.     

Gay Men's Knowledge of HIV Transmission and ‘Safe’ Sex: A Question of Accuracy

The study described in this paper is part of a project assessing the impact of the HIV epidemic on 535 men who have sex with men. These men were surveyed about their knowledge of HIV, their sexual practices, other issues concerning the transmission of HIV, and AIDS. This paper focuses on these men's beliefs about HIV transmission, their perceptions of the safety of a number of sexual and social practices, and the factors influencing these perceptions. The findings indicate, in general, that the men surveyed were moderately well informed about HIV transmission. Some twenty percent of the men were well-informed about both ‘safe’ and ‘unsafe’ sexual practices, a small number were ill-informed and the remainder, the majority, were well-informed about some aspects and ill-informed about others. The data suggest that information from the mainstream and gay press is not only differentially available but that information is processed and interpreted by the men in different ways. Variables which influence the manner in which information is interpreted are place of residence (locale), awareness of gay community posters and pamphlets, and the men's sexual practice; these are associated with cautiousness or rashness in the men's judgments of safety and risk.     

Understanding the experience of moving a loved one to a long-term care facility:family members' perspectives

This project was designed to develop an understanding of family members' experiences of moving a loved one to a long-term care facility and to identify ways in which facilities might help ease this process. Twenty-one semi-structured interviews were conducted with family members who had recently moved a relative into one of three long-term care facilities in Southern Ontario, Canada. Several factors appeared to contribute to the overall experience of the move to long-term care and either served to impede or facilitate a positive transition for families. These factors included: the experience during the waiting process, preparation for the move, ease of the actual move, control over decisions, communication throughout the process, support from others, and family and resident perceptions and attitudes towards the move. Easing the difficult aspects of moving a loved one to a long-term care setting can be facilitated with better preparation and support from facilities and community services.     

Peers' influence and African-American youth in public housing

Drawing from problem behavior theory (PBT), this study investigates whether the relationship between exposure to delinquent peers and delinquent behavior is moderated by peer influences as well as by generalized self-efficacy and an adolescent's attitudes toward deviance. We also explore how gender may influence these relationships. A sample of 401 African-American adolescents living in public housing developments in two large US cities was recruited for this investigation. The preliminary analyses included t-test and bivariate correlations, while our primary analysis included hierarchical regression analysis. The regression analysis included two-way and three-way interaction terms to assess the moderating effects of peer influences, generalized self-efficacy, and attitudes toward deviance as well as gender, respectively. Results indicate that the effects of exposure to delinquent peers depend on peers' influence over adolescents and other factors. Findings provide partial support for PBT and suggest that the relationship between exposure to delinquent peers and delinquent behavior, with regard to minority youth living in urban public housing, merits further investigation. Results have the potential to guide preventative interventions targeting African-American youth living in urban public housing and also inform future inquiries into the lives of such youth.     

Identifying intraclass correlations necessitating hierarchical modeling

Hierarchical binary outcome data with three levels, such as disease remission for patients nested within physicians, nested within clinics are frequently encountered in practice. One important aspect in such data is the correlation that occurs at each level of the data. In parametric modeling, accounting for these correlations increases the complexity. These models may also yield results that lead to the same conclusions as simpler models. We developed a measure of intraclass correlation at each stage of a three-level nested structure and identified guidelines for determining when the dependencies in hierarchical models need to be taken into account. These guidelines are supported by simulations of hierarchical data sets, as well as the analysis of AIDS knowledge in Bangladesh from the 2011 Demographic Health Survey. We also provide a simple rule of thumb to assist researchers faced with the challenge of choosing an appropriately complex model when analyzing hierarchical binary data.
