What is the Enrollment Run-in Target Generator?
- Calculates a participant's target or goal for the study duration on data collected during the run-in period.
- This allows participants to have a realistic and attainable goal based on real data
- Allows each participant to have a different goal based on how they did during the run in
- Ability to set different goal parameters including
- Set minimum days needed to calculate goal
- Exclude certain values
- Multiply baseline calculated to increase goal for the study period
- Specify goal rounding criteria
...
- Start Day: Select the day that the target should start. If you only have one target, this is typically at study start, or Day 0.
- End Day: Select the day that the target should end. Again, if you only have one target for the study duration, this is typically the last day in the study.
Tip! Want to create a target ramp up? You can do this with the scheduling feature! - Example: Target runs from Day 0-29 and then the target increases on Day 30-59 and increases again Day 60-89. You can achieve this by creating 3 different targets!
Criteria
- Minimum number of days needed to calculate target: Set the number of days of data needed to calculate a participant's target
- Example: If a run-in is 2 weeks, we want to sure that we have at least 7 days of data from the participant's device in order to calculate the target.
- Why? Any less than 1 week of data may not accurately reflect their activity level.
- Why? Any less than 1 week of data may not accurately reflect their activity level.
- Example: If a run-in is 2 weeks, we want to sure that we have at least 7 days of data from the participant's device in order to calculate the target.
- Evaluate: Choose either entire run-in (i.e. all 14 days) or only the last X of the run-in (i.e. last 10 days)
- Why would I choose only last X days? This option allows participants to get used to wearing, syncing, and charging the device. It allows them a few days to get 'acclimated' to having a new device, scrapping the earlier data that might not reflect their true activity levels.
Calculation
- Exclude values less than: Allows you to set the minimum value accepted to calculate the goal
- This field can also be left blank
- Example: for a step target, exclude values less than 1000. Why? Anything less than 1000 probably doesn't truly reflect the participant's normal step count, or the participant was sick, or is having device issues
- Exclude values greater than: Allows you to set the maximum value accepted to calculate the goal
- This field can also be left blank
- Example: for a step target, exclude values greater than 20,000. Why? Anything more than 20,000 may make someone's goal too high and unattainable once it's multiplied. You may want to get rid of the high values so that they don't skew participant's step goal.
- Multiply run-in target by: Allows you to set how much the value should increase by based on the average calculated from the baseline.
- This field can also be left blank - the participant's target will then just be an average of their run-in
- Example: for a step target, multiply run-in by 1.2. This will increase the step count by 20%.
