Free ADHD Self-Assessment Screening

What is ADHD?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning. According to the Centers for Disease Control and Prevention (CDC), ADHD affects approximately 6.1 million children and an estimated 4.4% of adults in the United States. It is one of the most common neurodevelopmental disorders of childhood and frequently persists into adulthood.

ADHD is not simply a matter of willpower or laziness. Brain imaging studies have shown differences in brain development and functioning in people with ADHD, particularly in areas involved in attention, impulse control, and executive function. It has a strong genetic component — if a parent has ADHD, their child has approximately a 50% chance of also having it. For a detailed overview of symptoms across all three ADHD types, read our guide on ADHD signs, symptoms, and next steps.

The Three Types of ADHD

The American Psychiatric Association (APA) recognizes three presentations of ADHD:

• Predominantly Inattentive Presentation — Difficulty sustaining attention, following through on tasks, organizing activities, and avoiding distractions. Often described as "daydreaming" or "spacey." This is the most commonly missed presentation, especially in women and girls.
• Predominantly Hyperactive-Impulsive Presentation — Excessive fidgeting, difficulty sitting still, talking excessively, interrupting others, and making impulsive decisions. More commonly identified in childhood because symptoms are more visible.
• Combined Presentation — Symptoms of both inattention and hyperactivity-impulsivity. This is the most common presentation overall.

ADHD in Adults

While ADHD is often associated with children, it frequently continues into adulthood. Adult ADHD symptoms may look different from childhood symptoms — hyperactivity often decreases and may manifest as restlessness, while inattention and impulsivity tend to persist. Common adult ADHD signs include:

• Chronic difficulty with time management and deadlines
• Trouble organizing tasks and prioritizing responsibilities
• Frequently losing important items (keys, phone, wallet)
• Difficulty maintaining focus during meetings or long conversations
• Impulsive spending or decision-making
• Restlessness or feeling "driven by a motor"
• Difficulty relaxing or engaging in leisure activities quietly

About This Screening

This 18-question screening tool evaluates three core symptom areas referenced in the WHO Adult ADHD Self-Report Scale: inattention, hyperactivity, and impulsivity. For each question, you rate how often you experience the described behavior on a scale from "Never" to "Very Often."

Your responses are scored to produce a risk-level assessment (Low, Moderate, or High Risk). This screening is not a diagnosis — it is designed to help you decide whether to seek a professional evaluation. Only a qualified healthcare professional can diagnose ADHD through comprehensive clinical assessment.

When to Seek Professional Help

Consider scheduling an evaluation with a healthcare professional if:

• Your screening results suggest moderate or high risk
• ADHD-like symptoms have been present since childhood (before age 12)
• Symptoms significantly impact your work, relationships, or daily life
• You've been told by others that you seem inattentive or impulsive
• You struggle with tasks that others seem to complete easily

A proper ADHD evaluation typically involves a clinical interview, symptom rating scales, medical history review, and possibly neuropsychological testing. Your primary care physician, a psychiatrist, or a psychologist can conduct this evaluation.

FAQ

Can this test diagnose ADHD?

No. This is a screening tool only. A proper ADHD diagnosis requires comprehensive clinical evaluation by a qualified healthcare professional, including interviews, behavioral assessments, and possibly neuropsychological testing. No online test can replace an in-person clinical evaluation.

What should I do if my score is high?

If your screening results suggest ADHD symptoms, we strongly recommend scheduling an appointment with a psychiatrist, psychologist, or your primary care physician for a comprehensive evaluation. Bring your screening results to the appointment as a starting point for discussion.

Is ADHD treatable?

Yes. ADHD is one of the most well-researched and treatable mental health conditions. Treatment options include behavioral therapy (such as CBT), medication (stimulant and non-stimulant options), ADHD coaching, and lifestyle modifications including exercise, sleep hygiene, and organizational strategies. Many people benefit from a combination of approaches.

Can adults have ADHD?

Yes. The CDC estimates that about 4.4% of U.S. adults have ADHD, though many remain undiagnosed because symptoms can look different in adults than in children. Hyperactivity often decreases with age, while inattention and executive function challenges tend to persist.

What are the three types of ADHD?

ADHD has three presentations: Predominantly Inattentive (difficulty focusing, easily distracted), Predominantly Hyperactive-Impulsive (fidgeting, impulsive decisions), and Combined (symptoms of both). The presentation can change over a person's lifetime, and a person's diagnosis may be updated based on their current symptoms.
