Randomized Evaluation of Voucher Interventions for Value and Effectiveness (REVIVE) in Philippines

Study Summary

This study aims to evaluate whether revised food voucher programs, combined with nutrition education sessions, can improve food security, dietary quality, nutrition knowledge, and nutritional outcomes among low-income households in the Philippines. Researchers will compare different monthly voucher amounts-Philippine Peso (PhP) 3,000, PhP 5,000, and PhP 8,000-with a no-voucher control group to determine which approach is most effective. The main questions the study aims to answer are: * Do food vouchers improve household food security, reduce hunger, and improve dietary quality and nutrient intake? * Do larger voucher amounts lead to greater improvements in nutrition and health outcomes? * Does enhanced nutrition education improve nutrition knowledge and healthy eating practices? Participants will: * Receive either a monthly food voucher or no voucher, depending on study group assignment * Attend nutrition education and Social and Behavior Change Communication (SBCC) sessions if assigned to a voucher group * Complete household interviews on food consumption, household expenditures, food security, and nutrition knowledge * Participate in dietary assessments and anthropometric measurements for women and children under 5 years of age

Primary Outcome

Composite measure of nutrition knowledge assessed using a structured questionnaire administered to the primary household meal planner. The instrument includes items on food groups, dietary diversity, micronutrient-rich foods, maternal and child feeding practices, and understanding of voucher allocation rules. A total score will be constructed by summing correct responses and standardizing across respondents. Subdomain scores (e.g., dietary diversity knowledge, micronutrient knowledge, child feed
