​How long will this study last?

SECHURA is a longitudinal study that will transpire over the course of three years. In wave 1 (2023-2024), you will be asked to complete an in-home survey. This will be administered by one of our trained field interviewers and take approximately 60 minutes to complete. Immediately after the survey, you will be asked to install the LifeData app on your smartphone (we will provide you a loaner phone if you do not own one). You will use this app to answer 4 mini surveys (~1-3 minutes each) per day for the next 7 days. This will constitute your participation for wave 1. You will be re-contact in wave 2 (2025-2026) and asked to complete another in-home survey and another 7 days of the smartphone mini surveys.
