Remote Testing and Symptom Measurement for ADHD: Insights into the QbCheck Tool

New research in attention-deficit/hyperactive disorder (ADHD) covered QbCheck, an objective, remote test for core ADHD symptoms.¹ The test is designed to complement other ADHD measures like structured interviews and subjective rating scales, to provide objective data in a clinician’s evaluations.² Ragini Sanyal, a lead researcher involved in developing the tool, shared more about recent data on the tool’s efficacy.

Psychiatric Times: Your recent study explored objective testing for ADHD, can you elaborate on the effectiveness of this measure in the course of treatment?

Ragini Sanyal, MS: Our study followed 994 patients completing ADHD assessment and treatment entirely remotely. After diagnosis and stimulant medication optimization, we saw a 41% improvement in objective ADHD symptoms measured by QbCheck. Patients also reported significant reductions in ADHD symptoms, depression, anxiety, and even alcohol and nicotine use, along with major improvements in quality of life. Importantly, objective improvements closely aligned with patient‑reported improvements, showing the tool’s real clinical relevance.

PT: With your findings of patient improvement measured by QbCheck, what do you think the implications are for future ADHD research?

Sanyal: These results show that large‑scale, remote ADHD assessment is both feasible and effective, laying the groundwork for expanded research into digital‑first ADHD care, predictive models for treatment response, and more precise medication optimization. The strong, real‑world outcomes demonstrate that remote pathways can deliver clinically robust results, making them especially valuable for underserved or high‑demand regions. Because we also observed improvements in depression, anxiety, and substance use, the findings suggest that effective ADHD treatment may offer broader mental health benefits. Future research should explore the mechanisms linking ADHD symptom improvement to reductions in these comorbid conditions.

PT: For clinicians looking at various ADHD testing methods, what is the most essential point from this research you would emphasize?

Sanyal: The key message is that our objective ADHD testing meaningfully reflects real‑world clinical change and should be considered a valuable complement to traditional patient‑reported measures. Our data show that when patients improve on QbCheck, they also report fewer ADHD symptoms, better mood, and improved quality of life. This reinforces the clinical utility of objective testing in both diagnosis and ongoing treatment monitoring—especially in remote or high‑volume care environments. Clinicians can use objective data to increase diagnostic confidence, guide medication titration, identify inadequate treatment response earlier, and streamline care while maintaining quality.

PT: You explained QbCheck measures ADHD symptoms; can you share how the objective testing measure was developed?

Sanyal: QbCheck is a standardized computerized test developed to quantify the 3 core dimensions of ADHD: inattention, hyperactivity, and impulsivity. It combines a continuous performance task with motion tracking to produce 5 performance parameters that feed into the total symptom score.

QbCheck was designed to:

• provide a norm‑referenced, age‑adjusted performance profile,
• reduce reliance on subjective symptom reporting,
• help clinicians detect ADHD‑related deficits not always observable in interviews,
• deliver consistent, replicable measurements across clinical settings—including fully remote environments.

Ms Sanyal is the head of clinical research at Qbtech.
