Why screening tools exist

Screening questionnaires are designed to help people notice patterns that might be easy to miss or normalize over time. They are not medical diagnoses. Instead, they offer a structured way to reflect on common ADHD traits like inattention, impulsivity, restlessness, emotional regulation, and time perception.

If you are wondering “Do I have ADHD?”, a screening tool can be a gentle first step. It can help you organize your observations, identify which areas are most challenging, and decide whether you want to seek a professional evaluation. You can take a free ADHD self-assessment here.

What a screening can and cannot do

A screening can:

  • Highlight patterns that are consistent with ADHD traits.
  • Show which categories are most impactful for you.
  • Give you language to describe your experience to a clinician.

A screening cannot:

  • Confirm or rule out ADHD.
  • Replace a clinical interview and history.
  • Account for every factor that might affect attention, energy, or mood.

ADHD can look different across people, ages, and contexts. A qualified healthcare professional considers a full history, development timeline, and daily functioning before diagnosing.

How the Open ADHD assessment is designed

An original self-reflection questionnaire for adults (18+). It has not been independently clinically validated. It cannot diagnose ADHD, identify a subtype, or estimate your likelihood of having ADHD.

Results count the questions you answered Often or Very often in each category. You can review every answer and copy or download a text summary. These counts are not severity levels or diagnostic thresholds.

What to do with your results

If difficulties affect daily life, consider discussing your experiences with a qualified healthcare professional, regardless of your answers. You can bring specific examples and questions to the appointment.

When to seek professional help

If ADHD-like traits are consistently interfering with work, relationships, or daily routines, it is worth talking to a healthcare provider. Many adults go undiagnosed for years because they adapt or mask symptoms. A clinical evaluation can help you understand what is happening and explore support options. Our doctor visit preparation guide can help you feel ready for the conversation.
