What makes this project unique

The project employed a rigorous experimental research design—an advanced and relatively uncommon methodology in applied social research in Armenia—to assess the effectiveness of different demand-side incentives. Its evidence-based approach enabled the systematic comparison of intervention results and generated reliable findings to inform health policy decisions.

Participants were randomly assigned at the individual level to four intervention groups and a control group. The interventions combined personalized screening invitations with different incentive mechanisms, including peer information and unconditional or conditional pharmacy vouchers.

MEDIA-MODEL conducted the baseline face-to-face survey with 1,600 participants in the intervention groups, while the 400-person control group was intentionally surveyed only at the end of the intervention period to avoid influencing their screening behavior. Screening outcomes for the full sample were subsequently verified through Armenia’s national health administrative database. This combination of random assignment, intervention and control groups, survey data, and administrative health records enabled a robust comparison of intervention effects and demonstrated MEDIA-MODEL’s capacity to implement complex impact-evaluation protocols.
