How to Get Tested for ADHD: A Guide for Adults

Many adults begin considering ADHD testing after years of difficulties with attention, organization, time management, or completing everyday responsibilities.

Some have struggled since childhood but were never formally evaluated. Others begin recognizing possible ADHD symptoms when academic, occupational, or family responsibilities become more demanding.

If you suspect that ADHD may be contributing to your difficulties, a professional evaluation can help determine whether your experiences are consistent with attention-deficit/hyperactivity disorder or another condition.

What Are Common Signs of ADHD in Adults?

ADHD involves persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning.

In adults, possible symptoms include:

• Difficulty sustaining attention
• Frequent distractibility
• Forgetfulness in everyday activities
• Problems organizing tasks and responsibilities
• Difficulty completing projects
• Losing important items
• Restlessness
• Interrupting others
• Impulsive decision-making
• Difficulty managing time and deadlines

ADHD does not look identical in every individual.

Some adults primarily experience inattentive symptoms, while others demonstrate more prominent hyperactive or impulsive characteristics.

These symptoms are not unique to ADHD, which is why diagnostic assessment is important.

Who Can Diagnose ADHD?

ADHD may be diagnosed by appropriately qualified healthcare professionals, including psychologists, psychiatrists, and certain other licensed clinicians acting within their professional scope.

The type of evaluation provided may differ by clinician and setting.

A psychologist conducting a comprehensive ADHD evaluation may examine developmental history, current symptoms, functional impairment, and relevant psychological or cognitive factors.

Step 1: Find a Qualified ADHD Assessment Provider

Begin by identifying a clinician experienced in evaluating ADHD in your age group.

For adults, it is helpful to find a provider familiar with how ADHD presents beyond childhood.

Consider asking whether the evaluation includes a developmental interview, assessment of other psychological conditions, and a written report.

The appropriate scope depends on the individual’s concerns and the purpose of the evaluation.

Step 2: Complete a Clinical Interview

The evaluation generally begins with a detailed discussion of symptoms and history.

The psychologist may ask about:

• Childhood attention and behavior
• Academic experiences
• Occupational functioning
• Organization and time management
• Relationships and daily responsibilities
• Sleep and medical history
• Anxiety, depression, and other psychological symptoms
• Previous evaluations or treatment

ADHD is a neurodevelopmental condition, so evidence of symptoms beginning during childhood is important.

However, a person does not necessarily need to have received a childhood diagnosis.

Step 3: Complete ADHD Assessment Measures

An evaluation may include standardized questionnaires and other measures examining attention, impulsivity, executive functioning, or related psychological characteristics.

Depending on the clinical question, the psychologist may also administer cognitive or computerized attention tests.

These measures provide additional information, but no single questionnaire or computerized test can independently establish or rule out ADHD.

The diagnosis depends on the integration of clinical history, symptoms, impairment, and other relevant evidence.

Step 4: Evaluate Other Possible Explanations

Attention difficulties can occur for many reasons.

Anxiety, depression, sleep disturbances, trauma-related symptoms, medication effects, and other conditions can affect concentration and executive functioning.

Autism and learning disorders may also coexist with ADHD or contribute to difficulties that warrant further investigation.

A comprehensive evaluation considers whether ADHD is the best explanation, whether multiple conditions are present, or whether another factor better accounts for the symptoms.

Step 5: Review Your Results and Recommendations

Following the assessment, the psychologist integrates the findings and explains the diagnostic conclusions.

A written report may include:

• Relevant developmental and clinical history
• Assessment findings
• Diagnostic impressions
• Functional strengths and difficulties
• Treatment recommendations
• Possible educational or workplace accommodations

If ADHD is diagnosed, recommendations may include psychotherapy, behavioral strategies, organizational supports, and consultation with a qualified prescribing clinician regarding medication.

If ADHD is not diagnosed, the evaluation may still identify other factors contributing to the reported difficulties.

Do Adults Need Childhood Records for ADHD Testing?

Not necessarily.

Childhood report cards, previous evaluations, or information from family members can be helpful when available.

However, many adults do not have access to these records.

A clinician can explore developmental history through detailed interviews and other available sources, while acknowledging any limitations in the evidence.

Can ADHD Testing Be Done Online?

Some components of ADHD evaluation can be completed remotely.

Telehealth interviews and standardized questionnaires may be appropriate in many circumstances.

However, certain testing procedures may require in-person administration or specific conditions to maintain validity.

The clinician should determine the appropriate format based on the referral question and selected measures.
