WURS-61: Wender Utah Rating Scale
Retrospective childhood ADHD assessment. Adults rate symptoms from ages 5–10 to establish the early onset required for a DSM-5-TR ADHD diagnosis.
WURS-25 Score Interpreter
Subthreshold elevation. Consider collateral history, childhood records, and comorbidities before concluding.
Sum the 25 scored WURS-25 items only (not all 61). Each item is rated 0–4; maximum total is 100. Higher scores indicate greater retrospective childhood ADHD symptom burden.
| WURS-25 total score | Interpretation |
|---|---|
| 46+ | Consistent with childhood ADHDAchieves 86% sensitivity and 99% specificity vs. depressed adults at this threshold (Ward et al., 1993). Supports childhood onset; combine with current-symptom screening. |
| 25–45 | Borderline — clinical judgment requiredSubthreshold elevation. Consider collateral history, childhood records, and comorbidities before concluding. |
| 0–24 | Not consistent with childhood ADHDScore below borderline range. Recall bias from current mood disorders should be considered if the clinical picture is otherwise suggestive. |
Ward MF et al. Am J Psychiatry. 1993;150(6):885-890. Cutoff ≥46 per Ward et al. (1993); borderline range 25–45 reflects a commonly used clinical convention.
Foundational Context
Developed by Ward, Wender, and Reimherr (1993), the Wender Utah Rating Scale (WURS) was created to evaluate childhood behaviors associated with ADHD in adults. It supports the DSM-5-TR requirement that ADHD symptoms were present before age 12.
The WURS is unique in its focus on the "Utah Criteria" for ADHD, which includes emotional dysregulation and mood lability in addition to classic core symptoms of inattention and hyperactivity.
What the Assessment Measures
The full WURS-61 consists of 61 retrospective items. However, clinical scoring typically uses a specific subset of 25 items (the WURS-25). When clinicians refer to a "WURS score," they mean the WURS-25 total. Adults rate how they experienced symptoms during childhood (approximately ages 5–10) on a 5-point scale (0 = Not at all/Slightly, 1 = Mildly, 2 = Moderately, 3 = Quite a bit, 4 = Very much). The remaining 36 items are not included in the scored total but may be reviewed clinically.
Core Childhood Symptom Domains:
- Attention & Concentration: Trouble concentrating, daydreaming, difficulty completing work.
- Impulsivity: Acting before thinking, getting into trouble, impulsive planning.
- Behavior & Conduct: Fighting with children, being rebellious, trouble at school.
- Academic & Learning: Trouble with reading or arithmetic, underachieving.
- Emotional Dysregulation: Moody, irritability, hot temper, low frustration tolerance.
Interpretation Guidelines
Sum only the 25 WURS-25 items for the clinical score (maximum 100).
- 0–24: Not consistent with childhood ADHD.
- 25–45: Borderline, clinical judgment required. Consider collateral history.
- ≥36: Elevated, higher sensitivity cutoff (used in some settings).
- ≥46: Consistent with childhood ADHD. Validated threshold achieving 86% sensitivity and 99% specificity vs. depressed adults (Ward et al., 1993).
Important: The WURS establishes childhood onset; the ASRS (Adult ADHD Self-Report Scale) should be used to screen for current symptoms.
Administration Considerations
- Format: Self-administered, typically 10 minutes. Public domain, no licensing required. Validated in English, Dutch, Italian, and Spanish.
- Instructions: Rate symptoms based on childhood experience (ages 5–10) only.
- Scoring: Sum only the designated 25 items for the WURS-25 total.
- Integration: Best used alongside the ASRS. Administer the ASRS at intake to screen for current ADHD symptoms; if Part A is positive (4+ responses), follow up with the WURS-61 to assess childhood onset. A positive ASRS combined with a WURS-25 score ≥46 provides the strongest support for an adult ADHD diagnosis, satisfying both the current impairment and childhood onset criteria in DSM-5-TR. Corroborate with childhood records or parent reports where possible.
- Documentation: Record the WURS-25 total score in the Objective section of your note, with the interpretation (e.g., "WURS-25: 52, consistent with childhood ADHD onset").
Psychometric Properties
- Internal consistency: Cronbach’s α ≈ 0.94.
- Sensitivity: 86% (at cutoff ≥ 46).
- Specificity: 99% (at cutoff ≥ 46 vs. depressed adults).
- Validation: Ward et al. (1993).
Limitations
- Recall Bias: Current mood (especially depression) can distort retrospective reporting.
- Not Diagnostic Alone: Requires a full clinical interview and collateral history.
- Utah Criteria: Some items may not map directly to current DSM-5-TR ADHD symptom descriptions.

Frequently Asked Questions
What is the difference between the WURS-61 and the WURS-25?
The WURS-61 is the full 61-item questionnaire. Clinical scoring uses only the 25 items that most strongly differentiate adults with ADHD from non-clinical adults and depressed adults — this subset is called the WURS-25. When clinicians report a WURS score, they mean the WURS-25 total; the remaining 36 items are not counted but may be reviewed clinically.
What is a high WURS-25 score?
A score of 46 or higher on the WURS-25 (maximum 100) is considered elevated and consistent with childhood ADHD. In the original validation study, this cutoff correctly identified 86% of adults with ADHD while correctly classifying 99% of depressed adult controls. Scores between 25 and 45 are considered borderline and require clinical judgment.
Is the WURS self-report or clinician-administered?
The WURS is a self-report instrument. Adults complete it independently by recalling their own behaviour and experiences during childhood (approximately ages 5–10). It takes roughly 10 minutes to complete and requires no licensing.
Can the WURS alone confirm an ADHD diagnosis?
No. The WURS supports — but cannot substitute for — a full clinical interview. A positive WURS-25 score establishes retrospective childhood onset, which is one DSM-5-TR criterion for adult ADHD. Current symptoms must be confirmed separately (e.g., using the ASRS), and collateral history or childhood records should be obtained where possible.
