Take Our Free ADHD Screening Test

If you have been wondering whether ADHD (Attention Deficit Hyperactivity Disorder) may be affecting you or someone you care about, our free ADHD screening test can help identify whether further assessment may be beneficial.

This screening questionnaire is designed to identify common symptoms associated with ADHD in both adults and young people. The screening is completely free, takes only a few minutes to complete, and provides an indication of whether a comprehensive ADHD assessment may be appropriate.

Please note: This screening test is not a diagnostic tool and cannot provide a formal diagnosis of ADHD. Only a comprehensive clinical assessment conducted by appropriately qualified healthcare professionals can determine whether ADHD is present.

What Is ADHD?

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects attention, concentration, organisation, impulse control and activity levels. ADHD can affect children, adolescents and adults and may impact education, employment, relationships and daily functioning.

While many people occasionally experience difficulties with concentration or organisation, ADHD symptoms are typically persistent, have been present since childhood, and significantly affect everyday life.

Common characteristics of ADHD may include:

• Difficulty maintaining attention

• Forgetfulness

• Disorganisation

• Frequently losing items

• Impulsivity

• Restlessness

• Difficulty completing tasks

• Poor time management

• Difficulty prioritising activities

• Emotional dysregulation

Adult ADHD Symptoms

Many adults with ADHD report experiencing difficulties that may have been present since childhood but were never formally recognised.

Common adult ADHD symptoms include:

Inattention

• Difficulty concentrating during conversations

• Frequently becoming distracted

• Struggling to complete tasks

• Missing deadlines

• Poor organisation skills

• Losing important items

• Difficulty following instructions

Hyperactivity

• Feeling internally restless

• Difficulty relaxing

• Constantly feeling the need to be busy

• Talking excessively

• Difficulty sitting still for long periods

Impulsivity

• Interrupting conversations

• Making quick decisions without considering consequences

• Impulsive spending

• Difficulty waiting your turn

• Acting before thinking

ADHD Symptoms in Children and Young People

Children and adolescents with ADHD may experience:

• Difficulty paying attention in school

• Forgetfulness

• Excessive talking

• Fidgeting

• Difficulty remaining seated

• Interrupting others

• Poor organisation

• Difficulty following instructions

• Emotional outbursts

• Problems with homework completion

Symptoms can vary significantly between individuals and may present differently in boys and girls.

Why Take an ADHD Screening Test?

Many people live with ADHD symptoms for years before seeking support.

Taking an ADHD screening test may help you:

• Understand whether ADHD traits are present

• Identify symptoms affecting daily life

• Decide whether a formal assessment may be helpful

• Gain greater understanding of your experiences

• Access appropriate support and guidance

The screening is not designed to diagnose ADHD but can indicate whether further professional assessment may be worthwhile.

ADHD Screening Test vs ADHD Diagnosis

A screening test and a diagnostic assessment are very different.

ADHD Screening Test

A screening questionnaire:

• Takes only a few minutes

• Identifies potential ADHD traits

• Provides an indication of possible ADHD symptoms

• Cannot provide a diagnosis

Comprehensive ADHD Assessment

A formal ADHD assessment:

• Involves a detailed clinical interview

• Reviews developmental history

• Considers current symptoms

• Assesses impact on education, work and relationships

• Includes evidence from multiple sources where appropriate

• Determines whether diagnostic criteria are met

Only a qualified clinician can diagnose ADHD following a comprehensive assessment.

Is ADHD Common?

ADHD is one of the most common neurodevelopmental conditions worldwide.

Research suggests that ADHD affects approximately:

• 5% of children

• 2–4% of adults

Many adults remain undiagnosed and may only seek assessment later in life after recognising ongoing difficulties with attention, organisation or impulsivity.

ADHD and Mental Health

ADHD often occurs alongside other conditions, including:

• Anxiety

• Depression

• Autism Spectrum Disorder (ASD)

• Dyslexia

• Dyspraxia

• Sleep difficulties

• Low self-esteem

This is one reason why a comprehensive assessment is important, as symptoms can overlap with other conditions.

What Happens After Completing the Screening?

Once you complete the free ADHD screening test:

1. Review your results.

2. Consider whether the identified symptoms reflect your experiences.

3. If appropriate, seek advice from a healthcare professional.

4. Consider a comprehensive ADHD assessment if symptoms are significantly affecting your daily life.

If you choose to pursue a formal assessment, our multidisciplinary team can provide ADHD assessments that are completed in line with recognised clinical standards and NICE guidance.
