List Randomization Reveals Higher Condom Use Reporting in Women with HIV
Key Highlights
Medicine · Public Health
A study examined the utility of list randomization to reduce social desirability bias in self-reported sensitive behavioral data among women living with HIV of reproductive age in Lilongwe, Malawi. Researchers found that for four out of five sensitive statements, the prevalence difference between list and direct response methods was negligible, but self-reported consistent condom use was significantly higher using list randomization (53.1% vs 34.7%). This finding is methodologically important for public health researchers, as it provides evidence that list randomization can uncover underreporting of positive behaviors, which may lead to more accurate estimates for HIV prevention program evaluation and policy development in sub-Saharan Africa.
