A preliminary ethnographic decision tree model of injection drug users' (IDUs) needle sharing.
This article presents a preliminary ethnographic decision tree model of the needle sharing and HIV risk decision-making processes common to injection drug users (IDUs) in Houston, Texas. Ethnographic tree decision modeling is a rigorous qualitative method used to understand and predict how and why people in certain groups do things the way they do. The model was developed from data collected from focus group and individual interviews and naturalistic observations. The research participants were White, African-American and Latino male and female IDUs. The model presents IDUs' needle-sharing routines or scripts based on several prioritized criteria. The model supports other researchers' findings that social roles play an important part in shaping IDUs' needle sharing. Yet, the model attempts to specify the different kinds of roles and relationships. The model suggests that social roles IDUs play and the status hierarchy between roles are the translation mechanisms that organize IDUs' social relationships into drug and HIV risky activities.
