A Small Randomized Controlled Trial of Three Remote Methods to Collect Mental Health Data from Migrant Farmworker Adults.

There has been limited longitudinal study of the health of migrant farmworkers due to their migratory lifestyles and there are opportunities to test new remote data collection methods in this subpopulation. A small randomized controlled trial was conducted with 75 migrant farmworker families who were randomly assigned to one of three groups that participated by (1) telephone interview, (2) online survey, or (3) mobile app between June 2021-April 2022. Of 50 farmworker adults who completed the baseline survey, there was differential attrition with 21% of the telephone interview group, 18% of the online survey group, and 3.2% of the online app group completing the 2-month follow-up. Over this period, migrant farmworkers reported relatively few mental health problems but notable alcohol use problems. Online apps were less effective than traditional methods for remote data collection. Alcohol use problems among migrant farmworkers in the U.S. may be an issue that deserves further study.
