The WURS-25 is a retrospective self-report measure: an adult rates, on 25 items scored 0-4, how they were as a child. It quantifies childhood ADHD-related traits - inattention, impulsivity, temper and mood dysregulation, and academic difficulty - as remembered by the adult sitting in front of you. It exists because a diagnosis of adult ADHD requires evidence that symptoms began in childhood, and school records or parent informants are often unavailable.
It measures recalled childhood symptoms, not current ones. A high score supports the childhood-onset criterion of an adult ADHD assessment; it says nothing about present-day symptom severity, which needs a current-symptom measure such as the ASRS-5.
02 - Origin & purpose
Where it comes from.
Developed by Mark Ward, Paul Wender and Fred Reimherr, published in the American Journal of Psychiatry in 1993 (DOI: 10.1176/ajp.150.6.885). The 25 items were selected from the original 61-item Wender Utah Rating Scale because they best discriminated adults with ADHD from healthy controls and from adults with depression.
Purpose: to give clinicians a standardised, quantified retrospective account of childhood symptoms during adult ADHD assessment, reflecting the Utah criteria tradition of Wender's group, which emphasised mood and temper dysregulation alongside core inattentive and hyperactive symptoms.
03 - Scoring & cutoffs
How scoring works.
Twenty-five items, each 0-4 (not at all or very slightly through to very much), total 0-100. In the original 1993 validation a cutoff of 46 or above identified 86% of adults with ADHD while excluding 99% of healthy controls; it also correctly classified 81% of the depressed comparison group. In a 2018 Swedish psychiatric-outpatient study, where emotional instability and attention problems of other origins are common, the optimal cutoff was lower (39) with sensitivity 0.88 and specificity 0.70 - in mixed clinical populations, expect more false positives at any cutoff.
Score
Severity
Interpretation
0–35
Below threshold
Retrospective childhood ADHD symptoms below the screening thresholds.
36–45
Elevated
At or above the more sensitive cutoff of 36, which identified 96% of adults with ADHD in the original validation. Further assessment may be warranted.
46–100
Positive screen
At or above the standard cutoff of 46 (sensitivity 86%, specificity 99% against normal controls). Consistent with a childhood history of ADHD; corroborate with a full diagnostic assessment.
04 - Validation evidence
How well it performs.
Internal consistency is consistently excellent (Cronbach's alpha approximately 0.94). Factor analyses across languages support a three-factor structure - disruptive mood/behaviour, inattention/hyperactivity, and depression/anxiety - accounting for about 61% of variance in the Swedish translation study. Discrimination from healthy controls is strong; discrimination from other psychiatric presentations is more modest.

Instrument
Items
Time
When to reach for it
WURS-25
25
~5 min
Retrospective self-report of childhood ADHD symptoms in adults.
Comprehensive multi-informant assessment when a full profile is needed (licensed).
DIVA-5
structured interview
~90 min
The full diagnostic interview covering both childhood and adult criteria; the WURS-25 is a quick precursor, not a substitute.
WURS-61
61
~10 min
The original long form; rarely needed now the 25-item version carries the discriminative items.
06 - When to use it
Right tool, wrong tool.
The WURS-25 earns its place in adult ADHD assessment as a standardised way to document the childhood-onset criterion when records and informants are unavailable. It is a structured aid to developmental history, not a diagnostic test, and it should always sit alongside a current-symptom measure and clinical interview.
Reach for it when
-Adult ADHD assessments where the childhood-onset criterion needs standardised support
-Patients without school records or available informants
-Structuring the developmental-history part of an assessment interview
Reach for something else when
-Diagnosing ADHD by itself - no questionnaire does that
-Measuring current symptoms or treatment response - it is retrospective and static by design
-Patients with prominent depression, anxiety or emotional instability, where scores inflate and specificity drops
-Children and adolescents - it is written for adults looking back
07 - Confidence & precision
Reading the score with care.
An SEM and meaningful-change threshold have not been established, and would mean little: the construct (remembered childhood behaviour) should not change between administrations. Score drift across repeat administrations reflects recall and reporting effects, not symptom change. Treat scores near the cutoff as indeterminate and weigh them with informant history and interview findings.
08 - Limitations
What it cannot tell you.
Entirely dependent on retrospective recall, which is imperfect and mood-state-dependent - current depression can inflate remembered childhood difficulty; nearly half the items load on mood, temper and conduct rather than core DSM inattentive-hyperactive symptoms, reflecting the Utah criteria; specificity against other psychiatric disorders is far lower than against healthy controls; the original validation samples were small and predominantly male; no informant corroboration.
