List Randomization Reveals HIV Disclosure Reporting Bias in Malawi Study
Key Highlights
Medicine · Public Health
A study involving women living with HIV in Lilongwe, Malawi, applied list randomization to assess reporting biases for sensitive behaviors such as condom use and HIV disclosure. Researchers found that while most responses did not differ significantly between direct and list methods, self-reported consistent condom use was substantially higher under list randomization (53.1% vs. 34.7%), suggesting social desirability bias in direct responses. For a nurse-psychologist focused on chronic disease and health behavior, this finding highlights the importance of employing indirect questioning methods to obtain more accurate behavioral data in vulnerable populations, which is critical for designing effective prevention interventions in public health.
