Introduction: Fewer than 40% of people in the United States with HIV r
isk factors have been tested. However, almost 40% of untested individu
als with HIV risk factors in high AIDS prevalence cities stated in the
1991 National AIDS Behavioral Surveys (NABS) that they (1) ''planned
to be tested'' or (2) ''would get tested if no one could find out.'' M
ethods: We used longitudinal data from the 1991 and 1992 NABS (n = 5,5
43), which are nationally representative telephone surveys. We assesse
d whether untested individuals were tested one year later, and we used
logistic regressions to address two research questions: What are the
predictors of testing among untested individuals! What are the predict
ors of testing among untested individuals who ''planned to be tested''
or ''would get tested if no one could find out?'' Results: We found t
hat 30% of individuals who ''planned to be tested,'' 16% of individual
s who ''would get tested if no one could find out,'' and 11% of person
s with no intentions to be tested had been tested one year later (P <
.001). In regression analyses, risk factors and higher education were
key predictors of testing. Conclusions: It is encouraging that 30% of
individuals who plan to be tested did get tested within one year. Furt
her research, however, needs to examine testing barriers for the 70% o
f individuals who do not follow through on testing plans. The results
provide important information for targeting testing programs, developi
ng effective public policies, and addressing the debate over issues su
ch as name reporting and the availability of home HIV tests.
