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

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

Conditions

• Food Insecurity
• Undernutrition
• Diet Quality
• Nutrition Knowledge

Interventions

BEHAVIORAL

Food Voucher + SBCC (PhP 3,000)

Households receive a monthly food voucher valued at PhP 3,000 with a structured allocation of 10% for carbohydrates and oils, 45% for protein-rich foods, and 45% for fruits and vegetables. Vouchers are redeemable continuously throughout the month. The intervention is combined with six structured social and behavior change communication (SBCC) sessions focused on nutrition knowledge, healthy dietary practices, maternal and child nutrition, and WASH behaviors, delivered by trained local government staff.

BEHAVIORAL

Food Voucher + SBCC (PhP 5,000)

Households receive a monthly food voucher valued at PhP 5,000 with the same allocation structure (10% carbohydrates and oils, 45% protein, 45% fruits and vegetables) and continuous redemption design. The voucher is paired with six SBCC sessions covering nutrition education and behavior change topics related to diet quality and household nutrition.

BEHAVIORAL

Food Voucher + SBCC (PhP 8,000)

Households receive a monthly food voucher valued at PhP 8,000 with the same structured food group allocation and continuous redemption system. The intervention includes six SBCC sessions aimed at improving nutrition knowledge and dietary practices for maternal and child health.
