An Examination of the Performance of QbMobile in Differential Diagnosis Associated With ADHD Symptoms
What this study is about
The purpose of this study is to evaluate QbMobile's ability to collect objective data to identify specific symptom profiles in differential diagnoses (ASD, MDD, Bipolar Disorder and Anxiety Disorder) that are common with ADHD.
View original scientific description
The purpose of this study is to evaluate QbMobile's ability to collect objective data to identify specific symptom profiles in differential diagnoses (ASD, MDD, Bipolar Disorder and Anxiety Disorder) that are common with ADHD.
Interventions
DEVICE
Digital software application for cognitive performance and activity measurement (QbMobile, investigational device)
Participants will complete two non-invasive, 10-minute digital tests using the QbMobile Investigational Device-one at the clinic and one at home the following day. The tests objectively measure cognitive performance and activity levels and will not influence clinical diagnosis or treatment in this study.
Primary outcome measures
Identification of QbMobile Domain Profiles Using SD-Scores and Total Score (0-100)
Time frame: Two QbMobile tests: at the clinic (Visit 1) and remotely the following day (Visit 2)
QbMobile is a software application that measures cognitive performance and activity levels, including attention, impulsivity, activity, and movement patterns. The study will identify statistically distinct QbMobile domain profiles for each diagnostic group (ASD, MDD, Bipolar Disorder, Anxiety Disorder) using domain SD-scores and the QbMobile Total Score (0-100). (Component metrics are listed as secondary outcomes to meet single-measure reporting requirements.)
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

- Referred for an initial assessment for ASD, MDD, Bipolar Disorder or Anxiety Disorder (Separation Anxiety Disorder, Social Anxiety Disorder, Generalized Anxiety Disorder (GAD)) or has a prior diagnosis of one of the included disorders but is not currently receiving treatment;
- Meets DSM-5 or ICD-11 criteria for a primary diagnosis of ASD, MDD, Bipolar Disorder or Anxiety Disorder per sites standard clinical procedures;
- Have adequate sensory and physical ability to complete QbMobile;

- Has a concurrent medical diagnosis that could significantly affect test performance such as brain injuries, Parkinson's disease, current epilepsy or active seizures, amyotrophic lateral sclerosis (ALS), multiple sclerosis, dementias (e.g. vascular dementia, Alzheimer disease, etc);
- Has other conditions that could affect test performance (migraine or other types of severe headache, chronic or acute pain);
- Use of prescription medications (e.g., anxiolytics, sedative medications) taken on the day before completing QbMobile that could significantly affect performance;
- Substance use (e.g., alcohol, drugs) that may affect performance on the day of the tests.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
