Details and patient eligibility

About

This Phase II stratified randomized prevention trial will assess the efficacy of a behavioral economic theory-based financial incentive drawing program versus a control regimen to promote early childhood caries (ECC) preventive health behaviors (toothbrushing performance) for young children of predominantly Latino parents/caregivers in Early Head Start (EHS) and day care center programs.

Incentive Drawing
Experimental group
Description:
Eligible to earn a weekly drawing entry with different winning probabilities during the 6-month incentive intervention period. Possible winnings depend on toothbrushing performance: low adherence threshold (brushing child's teeth once per day for 7 days in a week) will have an 18% chance of winning $25 and a 1% chance of winning $50 (expected $5 payout); high adherence threshold (brushing twice per day for 14 days in a week) will have a 34% chance of winning $25 and a 3% chance of winning $50 (expected $10 payout).
Treatment:
Behavioral: Drawing Incentive
Control - Delayed Incentive
No Intervention group
Description:
No rewards during the first 12 months, but information on toothbrushing performance. After the Month 12 follow-up visit, may opt to participate in a delayed 6-month open label extension to earn the same monetary rewards the intervention group could earn Baseline through Month 6. Not a formal part of this trial, but rather a necessary condition to assure all participating parents/caregivers have the chance to earn the same monetary incentives.
