Total Score
Age-Adjusted Threshold
Scores above the cutoff for the test-taker's age group are consistent with ADHD-related executive functioning deficits.
| Age group | Cutoff (>) |
| Ages 18–34 | > 48 |
| Ages 35–49 | > 51 |
| Ages 50–64 | > 48 |
| Ages 65+ | > 40 |
The BDEFS-SF is a screening instrument, not a clinical diagnostic tool for ADHD.
