Over the past two decades, the epidemic of HIV/AIDS has challenged
the public health community to fundamentally rethink the framework
for preventing infectious diseases. While much progress has been
made on the biomedical front in treatments for HIV infection,
prevention still relies on behaviour change. This book documents
and explains the remarkable breakthroughs in behavioural research
design that have emerged to confront this new challenge: the study
of partnership networks. Traditionally, public health research
focused on the "knowledge, attitudes, and practices (KAP)" of
individuals, an approach designed for understanding health-related
behaviour like seat-belt wearing and cigarette smoking. For HIV and
other sexually transmitted infections, however, there are at least
two people involved in transmission. This may not seem like a big
difference, but in fact it changes everything. First, it means that
your risk depends on your partners - and on their partners, and
their partners: it depends on your position in the network of
partnerships. Consider, for example, the rise of infections among
monogamous women. Second, it means that individuals are not free to
simply change their behaviour - condom use, or abstinence, needs to
be negotiated with a partner. both the epidemiology of risk and
constraints to behaviour are therefore a function of the
partnership network. And our ability to design effective prevention
strategies depends on our ability to measure and summarize that
network. Using the traditional research designs, you would not see
this network at all - you would only see the unconnected nodes.
They key to solving this problem lies in Network Analysis, before
now a relatively obscure subfield in Sociology. For empirical
studies of networks to become feasible, however, many problems had
to be solved. This book documents the rapid progress that has been
made. It brings together eight pioneering studies that have sought
to map the networks that spread infection around the world. Each
chapter reviews the questions that drove the study, the changes in
methodology that were needed to implement the network survey, the
mistakes and successes encountered, and the central findings that
the network design made possible. An introduction provides an
overview of network survey design, a glossary provides a summary of
network terminology, and example questionnaires from each study
provide a template for further research. This is a unique and
valuable resource for the international public health research
community.
