ADHD Test for Adults (ASRS-v1.1)

The ASRS-v1.1 is the World Health Organization-endorsed screening tool for adult ADHD, developed by Kessler et al. (2005). The 6-item Part A screener is highly sensitive (68.7%) and specific (99.5%). Full 18-item version maps to DSM-5-TR inattention and hyperactivity/impulsivity symptom domains.

ADHD in Adults: What to Expect

Adult ADHD affects an estimated 4–5% of adults worldwide, yet a substantial proportion go undiagnosed, particularly women and individuals from underrepresented groups, who often present with primarily inattentive rather than hyperactive symptoms. ADHD is a neurodevelopmental disorder that persists from childhood, though presentations evolve significantly with age: overt hyperactivity typically decreases while inattention, executive dysfunction, and emotional dysregulation often remain prominent or intensify.

In adults, ADHD commonly presents as chronic difficulty with sustained attention, task completion, organization, and time management; impulsive decision-making; emotional dysregulation; inner restlessness; and difficulty with long-term planning. Rejection Sensitive Dysphoria (RSD), intense emotional pain in response to perceived criticism or failure, is a clinically significant feature in many adults with ADHD not yet included in formal diagnostic criteria.

The ASRS-v1.1 (Adult ADHD Self-Report Scale), developed by Ronald Kessler and colleagues in collaboration with the World Health Organization, is the primary evidence-based screening tool for adult ADHD. The 6-item Part A screener demonstrates sensitivity of 68.7% and specificity of 99.5% for DSM-IV ADHD diagnosis in clinical populations. For full assessment, the full 18-item ASRS maps directly to DSM-5-TR inattention (9 items) and hyperactivity/impulsivity (9 items) symptom domains. Diagnosis requires full clinical evaluation.

ASRS-v1.1 Screener

The first 6 items (Part A) are the validated screener. 4+ items shaded = positive screen.

ASRS-v1.1 © World Health Organization (2003). Free for clinical and research use. Positive ASRS screen does not diagnose ADHD, full evaluation required. DSM-5-TR requires ≥5 symptoms per domain (adults ≥17) with onset before age 12 and cross-setting impairment.

Adult ADHD Presentations

DSM-5-TR recognizes three presentations. Adults most commonly have Predominantly Inattentive or Combined presentations. Hyperactive-Impulsive presentation alone is less common in adults.

ADHD vs Common Mimics

Many conditions share symptoms with ADHD. Differential diagnosis and comorbidity assessment are critical components of ADHD evaluation.
