This article examines changes in network structure using data on conversational networks from the 1998 and 2001 rounds of the Malawi Diffusion and Ideation Change project. The principal aims are to show that network structure can change significantly in relatively short periods - in particular...

In the previous two decades there has been considerable progress in recognizing biases due to selectivity that are associated with the use of observational data to make causal inferences and in developing models to control for these biases statistically. Often there is a difference between...

We use a microsimulation model to estimate the proportions of rural Malawian brides and grooms who are already HIV positive when they marry. The model, a demographic model of reproduction and mortality overlaid with a model of disease transmission, incorporates behavioural input data derived...

This paper introduces a set of papers presented at the conference "Research on Demographic Aspects of HIV/AIDS in Rural Africa", held at the Population Studies Center, University of Pennsylvania, October 28-29, 2002. The aim of the conference was to provide a forum for the presentation of...

The social context of survey interviews is likely to be important in survey measurement in developing countries, where respondents expect to benefit from participation. In the recent literature on survey measurement, however, there are few attempts to analyze the impact of the...

This paper uses qualitative and quantitative data from married men and women in rural Malawi to examine how they comprehend their risk to HIV/AIDS and what preventive strategies they consider within marriage. Program efforts to promote behavior change have consistently focused on promoting...

In this paper, I investigate the ways that young men in rural southern Malawi talk about HIV and their own perceptions of risk. I relate these findings first to evolving gender relations in Malawi during the AIDS epidemic, and second to HIV prevention measures, with specific recommendations for...

This paper explores the significance of social relationships to two important stages in the process of sexual behavioral change in response to increased HIV/AIDS risk in rural Africa: the perceived risk of becoming HIV-infected through unprotected sexual intercourse and the preferred methods of...

I examine if and how rural Malawians alter their childbearing as a consequence of concern regarding the HIV/AIDS epidemic. The paper is motivated by the debate which opposes two ideas regarding the childbearing effect of high HIV infection rates and heightened AIDS mortality: one, the...

There are two main types of models of behavioral change. What are collectively referred to as "individual models" are the predominant frameworks for studying risk behaviors including those related to HIV/AIDS. Individual models focus on risk perceptions, attitudes, outcome expectations,...
