Patient Reports

The Quotient® ADHD Test report should be interpreted only by qualified professionals.

Select a patient below.

Research indicates that motion is one of the key indicators of hyperactivity. The Quotient® ADHD System uses the Motion Tracking System to measure movement 50 times per second and plots movement greater than 1 millimeter.
Baseline Assessment
Sarah, age 8. No medication.
Post-Medication Assessment
20 mg methylphenidate.

The table shows that the girl sat still an average of 73 milliseconds, which is in the 18th percentile for her age cohort. She also had more movements with greater total path and area. Her spatial complexity and temporal scaling metrics are outside of the normal range. While area and spatial complexity are flagged as the 16th percentile or lower, the rest of the motion parameters are at the lower end of the reference range. Sarah’s motion metrics did not improve. The age and gender matched percentile scores improved marginally for area and spatial complexity, but all of the results are still either less than the 16th percentile or at the lower end of the reference range.
The attention analysis section of the report plots incorrect and correct hits and passes on a time scale. Patients with attention problems tend to make a lot of mistakes and the time of response tends to be more variable than people without attention problems. People with good attention tend to get into a rhythm and the graph shows a fairly tight distribution around the mean response time. Key: + designates a target. X designates a non-target.

Accuracy of responses was 83.6% (376 correct responses out of 450 stimuli), with 13.3% incorrect passes (omission errors) and 19.6% incorrect hits (commission errors). These results indicate a problem with both inattention and impulsivity, although the commission errors do fall within the reference range. The graphs show loose scatter, which is reflected in the variability (4th percentile) and normalized response time (25th percentile) in the table. Note that response time (latency) increases over the course of the test, as designated by the average time in each 5 minute block on the graph. Attention analysis results indicate that Sarah’s focus improved in this post-medication assessment. Accuracy of responses improved to 95.5%. Omission errors were reduced to 2.7%, or the 54th percentile for her age group. Likewise, the variability score improved from the 4th percentile to the 67th percentile, well within the reference range.
The Quotient® ADHD System analyzes 30 x 30-second blocks of data for the 15-minute test for children under 13 years old. The report summarizes the information on the attention state chart. It is easy to see how much time the patient is attentive/on task vs. impulsive vs. distracted vs. disengaged from the task.

The Quotient® ADHD System analyzes 30 x 30-second blocks of data and summarizes the information on the attention state chart. For the first 30 seconds, this child showed impulsive behavior, followed by 30 seconds of distraction, followed by 60 seconds on task, and so on. The table shows that she had 22 attention shifts overall, that she was on task for 12 of 30 (40% of the test), impulsive 30% and distracted 26.7% of the time. On task results were much improved for Sarah. There were only 6 attention state shifts, with only 2 30-second blocks of impulsive behavior and 1 30-second block of distraction.

System Index Likely Unlikely

The Quotient ADHD System Index integrates the motion and attention indices and summarizes the degree of agreement between the patient’s results and the database of Quotient® ADHD Test results obtained from subjects with ADHD.

The Quotient ADHD Scaled Scores are normalized calculations on a 10-point scale. Higher Scaled Scores indicate deficit in control of motion and attention compared to age and gender matched subjects. The Global Scaled Score is an average of the motion and attention scores.
