Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Prevalence of participant DUFB use over time, as assessed by an interviewer-administered survey using structured open-ended questions | Use of DUFB at baseline assessed with yes/no response. At each of the the 3 follow-up surveys waves (1.5 months, 3 months, and 5 months), participants will be asked if they have used DUFB in the past month (yes/no), and if yes, how many times. | 5 months | 
| Participant-perceived barriers and facilitators to DUFB use following educational intervention, as assessed by an interviewer-administered survey using structured open-ended questions and semi-structured focus group questions | Through an iterative process, three team members will independently conduct thematic analyses, compared codes, resolve discrepancies, and summarize key thematic findings. | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline fruit and vegetable consumption at 1.5 months, 3 months, and 5 months, as assessed by a validated 2 question fruit and vegetable screener | Servings/day range from 0 to >=4 (scale applied separately to fruit consumption and vegetable consumption. Change will be calculated from two time points at each of three follow-up periods (1.5 months, 3 months, and 5 months) minus the baseline | baseline, 1.5 months, 3 months, 5 months |
