Incentivized High-Frequency Micro-Surveys
RCTClinical Trial
Long recall windows in financial survey research introduce severe recall bias and high attrition rates among migrant populations. Utilizing mobile apps with short recall windows and continuous financial rewards enables researchers to capture accurate high-frequency transaction data.
Picture this
Instead of asking someone once a year to remember every dinner purchase, you give them a smartphone app that awards digital loyalty points every time they upload a receipt once a week, which they can exchange for real store gift vouchers upon reaching a target.
What the evidence says
The micro-survey protocol achieved a retention rate of 54% over 30 weeks while capturing 137,927 weekly survey observations verified through photo receipt submissions.
- Who was studied
- 8,248 initial enrolled Filipino migrants in Dubai and Sharjah, producing 4,458 retained participants across 137,927 weekly observations.
- How
- High-frequency panel tracking via the smartphone application "Padalapp" combining weekly micro-surveys, receipt photo uploads, and point-based rewards (25 AED voucher per 100 points).
What to do
Deploy mobile micro-surveys paired with point-based financial rewards to maintain high panel engagement and eliminate long recall periods in high-frequency financial studies.
From the source
"Upon reaching 100 points, the participant was awarded with a gift certificate of their choice... with a value of AED25 (UAE dirham) (US$6.81)... Because participants could respond to the survey on different days, the recall period asked about was always the period since the last date on which the participant recorded a survey response."
