Trailmaking Active Task Export Format

In the Trailmaking Active Task, the participant is prompted to touch a series of dots in order and the test tracks how many dots they touch correctly.

When your project uses the CSV export format for Survey Results, data for Active Tasks is exported in the file SurveyTrailmakingResults.csv. When your project uses the JSON export format, Active Task data is included in the file SurveyResults.json.

For a typical survey using this task, you'll expect to see:

  • One survey result each time the participant completes the survey.
  • One step result representing the Active Task.
  • One Trailmaking result for that step. The individual taps are captured within this result.

Sample JSON Export

Note that since the JSON export is included in the SurveyResults.json file, some of the reference keys either do not apply, or are part of the overall survey step data.
