A target is tied to a single field of a single source. For example, it might be generated for "Withings Nokia Blood Pressure Cuff", specifically for the "bloodpressure_systolic" field. If we need to evaluate multiple fields, we would generate multiple targets.
...
Targets can also be displayed on a participant's dashboard, either in a dedicated target card (such as in the Process vs. Outcomes /wiki/spaces/old/pages/21622391 study) or as an additional line in the device graph card (such as in the CDC Study/wiki/spaces/old/pages/21622375).

What studies have used targets in the past? How have they used them?
- Mullen-TIA Study/wiki/spaces/old/pages/21622374
- Simple targets for systolic = 140, diastolic = 90
- CDC Study/wiki/spaces/old/pages/21622375
- Phase 1 (first 6 months)
- Stepped target, losing 12 pounds over 24 weeks. Every 4 weeks their targets are reset - keeping the original 12 pound final target, but if they're above the trajectory, resets the targets to give them a new chance
- Phase 2 (months 6-18)
- Gives them a monthly option for whether they want to lose 0 or 1/2 pound per week for the next 4 weeks. This uses the goal setting survey developed as part of the /wiki/spaces/technical/pages/21594498 feature to ask them their goal.

- STEPP
- Start with baseline (average of first 14 days). Week 1 (DAYS 0-8) target is 10% of baseline, week 2 (DAYS 9-15) target is 25% of baseline, week 3 (DAYS 16-22) target is 40% of baseline, week 4 (DAYS 23-29) target is 55% of baseline
- Diabetes Gamification
- Step Count Target
- This study begins with a 14 day run-in period. Using run-in days 8-14 (actually, 7-13 because it starts on day 0) we calculate a step count baseline average ignoring any days under 1000 steps. We must have at least 4 days of valid data to calculate the baseline. If a baseline is able to be calculated, we will display that in Manage Participants. Research coordinators will let the participant choose a step goal 33%, 40%, 50%, or a custom amount higher than the calculated baseline average. We will generate targets starting from the baseline entered in the survey, increasing by 25% of difference between goal and baseline each week during 4 week ramp up period. Maintain goal from week 4 through end of study (week 52)
- Weight Goal Target
Participants will select a weight loss goal that is 6%, 7%, or 8% of their baseline rounded up to the next pound during an in-person visit. The weight loss goal will be set for the end of the first 6 months of the study. First week of study no change in weight. Steady decline from end of first week until 6-month mark. After 6 months: If the participant has met their goal they will be expected to maintain that weight for the remaining 6 months. If the participant has not met their goal they will the option of striving to achieve either the full amount remaining or half of the amount remaining by the end of study (12 months). The slope of the weight loss trajectory should be reset every 4 weeks to give those falling behind a chance to catch up and those farther ahead the ability to slow down.
