Behavioral and psychological responses to HIV antibody testing.

The development of tests to identify the antibody to human immunodeficiency virus (HIV) has made it possible to diagnose infection with the virus prior to the development of physical symptoms. The introduction of these tests raises questions regarding the effects of informing individuals of their antibody status. These issues include the emotional impact of telling individuals that they have been infected with a fatal virus and the usefulness of antibody testing in promoting behaviors that would reduce the spread of acquired immunodeficiency syndrome (AIDS). Research that has examined changes in psychological distress and in behaviors associated with HIV infection among individuals who have undergone antibody testing is reviewed. Methodological issues encountered in studying behavioral and psychological responses to antibody testing are identified, and directions for future research are offered.
