Study Summary
This study was intended to test if reframing an offer for a free follow-up eye examination could increase uptake within ongoing community-based screening program for low-income and minority populations in Baltimore City. This study evaluated the effect of offering participants a physical voucher they were told was redeemable for free follow-up, relative to simply telling participants that the follow-up appointment would be free of charge. The investigators assessed two forms of vouchers, one with estimated value information, and one without. The underlying hypothesis was that reframing these already free offers would increase uptake by increasing perceived offer value and increasing a sense of regret from not taking advantage of a "good deal."
