ADHD Testing & Diagnosis


Here at Coastal Ridge Health Services, the QbTest is an objective tool utilized by our clinical staff to accurately diagnose ADHD. In addition, the test is administered to optimize medication treatment if medication is needed. Comparison reports of performance on and off medication are objective and, in addition to the patient’s report of symptoms, can help us determine if the dosage is accurate for the patient.

The QbTest is an FDA cleared computer-based test for ages 6 to 60. It measures the core symptoms associated with ADHD including hyperactivity, impulsivity, and inattention/distractibility.

During the test, activity is measured by recording every millimeter the head moves. Impulsivity and inattention are measured by having the patient complete a continuous performance test, which includes pressing a button for certain symbols and not pushing the button for other symbols.

The testing is not dependent on language, reading, or mathematic skills, and the results are presented in a report that compares the patient’s performance against the same age and gender participants who do not have ADHD. Performance on the QbTest is also not affected by color blindness or previous video gaming experience. The test itself requires no computer knowledge or skill.

The report requires interpretation by a licensed medical professional in conjunction with a clinical interview and other rating scales.

For more information, please call our office (910) 821-1418. You can find more information about the QbTest by visiting their website at

Psychiatric Rating Scale

In addition to the QbTest, we also employ the completion of psychiatric rating scale instruments, which are symptom checklists which may be completed by patient, family members, employers and teachers.

CNS Vital Signs

CNS Vital Signs, a neuropsychological test to evaluate the neurocognitive status and brain function, is an additional tool we use to measure minor motor performance, attention, memory, and executive functions.

Clinical Reviews

A thorough clinical interview is integral to the diagnosis process. After completion, an appointment to go over test results is made to determine if more testing is needed.
