DCE-IMPACT: Identifying and Matching Individual's Preferences for HIV/AIDS Counseling and Testing

  • HIV counseling and testing (HCT) is a highly cost-effective intervention for increasing serostatus awareness, a point of entry into HIV care and treatment, and an important means of primary and secondary HIV prevention. Public health officials have called for dramatic increases in HIV testing to achieve an HIV-free generation. However, testing rates are plateauing, and repeat testing rates among those with ongoing risk remain low. Novel approaches are needed to increase the uptake of HCT, especially among high-risk groups.

    This study will identify the effect of an HIV-testing intervention designed using a novel, preference-based strategy. If successful, this work will demonstrate the utility of DCEs as a tool to replace the costly practice of iteratively implementing narrowly focused interventions with a structured approach for developing interventions matched to the specific preferences of intended target populations.
