When first trying DRUID, make sure to run it in Practice Mode a few times. Once you feel you’ve got the hang of it, proceed to Baseline Mode. It is imperative to complete a few Baseline tests while sober before using DRUID in Test Mode. Doing this assures the results are accurate to you personally. Try your hand at the app’s quizzes & puzzles a few times through, and you then should have established an accurate Baseline (your average score while unimpaired). Now you’re good to go! You’re able to use DRUID in Test Mode whenever you’d like – whether you’re just trying to sharpen your mental acuity, find out how a particular strain of marijuana affects you, or assist in determining your level of impairment.
DRUID has three modes: PRACTICE, BASELINE and TEST. Your DRUID score will likely show a higher level of impairment than you actually have as you are learning the tasks in DRUID, so that the more BASELINE runs you do, the more stable your BASELINE score will become. DRUID keeps an average of your past 10 BASELINE runs.
Consequently, in order to achieve a reliable and stable BASELINE score for a user who is unfamiliar with DRUID, it is necessary for the user to practice using DRUID several times before entering BASELINE mode.
Additionally, since the exact presentation of the stimuli in DRUID varies each time, there will be some variation in a user’s scores each time they take it. To control for this random variation, for each specific user, DRUID stores and averages the data from their ten most recent BASELINE attempts.
DRUID produces measures of reaction time, errors in decision making, motor tracking and balance, and an algorithm integrates these measures into an overall measure of impairment.
The more you use DRUID, the more accurate its results will be for you. You should do multiple BASELINE runs (each one takes only 5 minutes!) to get the best estimate of your unimpaired DRUID score. By doing so, this will increase the accuracy of any TEST run that you do to assess your level of impairment.
