Study Details

Study Description

Brief Summary

IDinsight is conducting a randomized controlled trial to assess the impact of various sized cash incentives for caretakers of infants that require a 9-month measles vaccination on the completion rate for the vaccine in Nigeria. The purpose of the experiment is to help New Incentives (NI) determine the optimal size of the incentive as they scale to the North West region of Nigeria.

Arms and Interventions

Arm Intervention/Treatment
No Intervention: Pure Control

Respondents received New Incentives' normal program.

Placebo Comparator: Reminder Call

Respondents received a call from a New Incentives' staff member similar to the treatment arms, but weren't offered additional incentives.

Behavioral: Call
A New Incentives' team member reminded caregivers of their child's measles immunization date and the total amount of incentive they would receive once their child was vaccinated. If the caregiver could not be reached on the first attempt, the team made additional attempts at different times of the day on five different days across two weeks (up to 10 attempts were made per caregiver).

Experimental: Small Additional Incentive

Respondents were told they would receive 1000 NGN more than originally promised by New Incentives' (either 2000 or 3000 NGN) when they brought their child for measles immunization.

Behavioral: Cash Incentive
During the phone call, New Incentives' team member promised a greater cash payment from New Incentives' staff members at primary health care facilities when infants enrolled in the program and received their measles vaccination.

Behavioral: Call
A New Incentives' team member reminded caregivers of their child's measles immunization date and the total amount of incentive they would receive once their child was vaccinated. If the caregiver could not be reached on the first attempt, the team made additional attempts at different times of the day on five different days across two weeks (up to 10 attempts were made per caregiver).

Experimental: Large Additional Incentive

Respondents were told they would receive 3000 NGN more than originally promised by New Incentives' (either 2000 or 3000 NGN) when they brought their child for measles immunization.

Behavioral: Cash Incentive
During the phone call, New Incentives' team member promised a greater cash payment from New Incentives' staff members at primary health care facilities when infants enrolled in the program and received their measles vaccination.

Outcome Measures

Primary Outcome Measures

  1. Measles Vaccination Coverage Rate [We assessed whether eligible infants received measles vaccination at any time during the 4 month study period. Children were a minimum of 9 months at the beginning of the study and a maximum of 7 years at the end of the study.]

    The outcome of interest is the measles coverage rate among the eligible randomized infants. Coverage is measured using the measles vaccination information recorded on the child's health card. The child health card information was immediately entered into the New Incentives' database by their field staff when they disbursed the cash incentives at program clinics. Information from the New Incentives' database was used for the analysis.
