The DRUIDapp is widely used in the scientific community to study impairment.
The DRUID® app is designed to assess a user’s level of cognitive and motor impairment due to any underlying cause. Informed by impairment research, the app requires users to perform four tasks that measure reaction time, accuracy of decision making, hand-eye coordination, time estimation, and balance. Importantly, three of the four tasks are divided-attention tasks.
All four tasks can be completed in just under three minutes. The app collects and statistically integrates hundreds of measurements, thereby producing an overall impairment score (T-score) ranging from 0 to 100. In practice, most T-scores fall between 30 and 70.
- Directly tests impairment
- Drugs, alcohol, fatigue, injury, illness
- 4 tasks take about 3 minutes
- Calibrated to measured blood alcohol concentration (BAC)
