Abstract
A demonstration project, currently in progress in Miami, is using an experimental research design to evaluate an AIDS intervention program among IV drug users and the sexual partners of IV drug users. At the time of the initial assessment, which includes a blood test to determine HIV serostatus and an extensive interview, study participants are randomized into either a standard or an enhanced intervention protocol. The enhanced intervention group receives more intensive counseling including individual as well as group sessions. Follow-up assessments of both groups are made at six-month intervals. The before/after comparisons will assess whether frequency of risk behaviors have changed and whether observed changes are greater in the enhanced group than the standard group. Randomization to two alternative intervention groups allows for the control of many potential biases that plague other types of before/after research designs.
