The purpose of this project is to support validation study, assessment of yield, and refinement of microcomputer software providing personal, anonymous, and self-administered risk assessment for HIV infection. The software, for which initial design and programming has been completed, incorporates educational text followed by an interactive interview. The risk assessment is based upon analysis of personal data by the software's expert system, which incorporates a probability equation. Users at risk for HIV are advised to follow up with an antibody test. The software writes anonymous case data to DOS files for interface with statistical software. The system does not require users to possess specialized training. Preliminary validation study of the software was assisted by the University of Oklahoma, and findings were consequently published in the fall 1991 issue of the journal AIDS Education and Prevention [3:(3):215-229].Awardee's statement of the potential commercial applications of the research:Potential licensees may be found in the form of state and local governments, public schools and libraries, clinics and various health facilities, universities, counseling centers, and private sector employers with employee health education programs.National Cancer Institute (NCI)
