| Feature | PLH (n = 29) | Mothers (n = 24) |
|---|---|---|
| Completing surveys during the day | Considered acceptable, given incentives and ability to customize | Considered attractive to some, acceptable to most, especially with the ability to elaborate or reflect on events at the end of the day |
| Completing surveys in the moment | Considered acceptable, given incentives, ability to customize, purpose, and privacy sensitivity | Attractive to some, especially with access to a ‘button’ for quick recording of an event |
| Reminders | Important for medication adherence | Customization important, random reminders problematic |
| Goal setting/monitoring | Potentially valuable for medication adherence, reducing risky sexual behavior, drug use, and stress | Opinions differed on content, some wanted in relation to food, others wanted motivational messaging |
| Feedback | Less opinionated on format | Did not want simple data summary |
| Password protection | Attractive and necessary, particularly for drug use and sexual behaviors | Not important, some considered it not attractive as they felt it increased user burden |
| Image capture | Context dependent but useful tangible examples were difficult to imagine | Attractive, as long as constrained to capture of food |
| Access to data | Less opinionated | Through phone |
| Stress button | Not discussed | Suggested by mothers |
| Peer support | Attractive to a few | Considered acceptable, especially with the ability to customize reminder timing |
| Data sharing | Attractive to some, especially if anonymized; does depend on question content | Attractive to some, especially with control over which data will be shared (e.g., a button at the bottom of a screen that keeps responses private) |
