This study examined factors associated with HIV testing intentions among a community sample of 255 never-tested Hispanic men. It compared (1) men who intended to test in the next 6 months with those who did not and (2) men who intended to test only on the day of the interview with those who intended to test in the next 6 months. Eighty-four percent of men had never been offered testing. Yet, 86% would accept testing if recommended by their doctor. The strongest multivariate predictor of testing intention was willingness to accept a physician-endorsed test. Almost 49% of men who intended to test in the next 6 months would only do so if the test were offered on the interview day. These findings highlight the importance of encouraging physicians, particularly in high-prevalence areas, to routinely recommend testing. They also suggest that for some men, there is a window of opportunity for testing that does not endure.
