KNOWLEDGE, STIGMA, AND HIV TESTING: AN ANALYSIS OF A WIDESPREAD HIV/AIDS PROGRAM

Using randomized methodologies, we study a common community HIV/AIDS program that seeks to promote HIV testing by improving knowledge and reducing stigmatizing attitudes. Contrary to expectations, the program has a substantial negative effect on HIV testing rates. We provide evidence of likely mechanisms behind the program's negative effect: it inadvertently increased misinformation about HIV transmission methods, and worsened HIV-related stigmatizing attitudes. Subsequent household-level randomized treatments providing correct information and addressing stigma concerns counteract the program's negative effect on HIV testing. These findings highlight the importance of improving knowledge and alleviating stigma concerns when promoting HIV testing.
