First, roughly how old are you?

Screening scores read differently at different ages. This lets us tell you what your result tends to mean in your decade, and what is worth ruling out first. It is not required. If you give it, only its decade is added to an anonymous daily count, with no identifier.

6 questions, about 1 minutes

About the ASRS v1.1

Adult ADHD Self-Report Scale (ASRS-v1.1) Screener. Copyright World Health Organization 2003; developed in conjunction with the Workgroup on Adult ADHD. Reproduced as an unmodified electronic version with attribution.

The Adult ADHD Self-Report Scale was developed with the World Health Organization alongside the revision of the WHO Composite International Diagnostic Interview. The full scale has 18 questions on the frequency of recent DSM-IV adult ADHD symptoms; the six-question screener reproduced here was selected from them by stepwise logistic regression to best match blind clinical diagnoses. In the 2005 validation sample of 154 respondents from the US National Comorbidity Survey Replication, which oversampled people reporting childhood ADHD that persisted into adulthood, the unweighted six-question screener outperformed the unweighted 18 questions, with 68.7 percent sensitivity, 99.5 percent specificity and 97.9 percent total classification accuracy. A screener with that profile misses about 31 percent of true cases (100 minus the 68.7 percent sensitivity) and rarely flags a false one, which is the property to keep in mind when reading a negative result.

How this page scores it: it counts the answers that fall in the instrument's shaded range, and reads the result against the bands the source publishes: 0 to 3 is below the screening threshold; 4 to 6 is positive screen. Every band's wording on the result page is ours, written from the source's guidance for that range, and a result at or above the follow-up threshold says so in plain words rather than as a color.

Scoring is the screener's own shaded-box method: items 1 to 3 count from 'Sometimes' and items 4 to 6 from 'Often'; four or more shaded answers across the six questions is a positive screen. The instrument is reproduced as published and scored the way its published source scores it. A screening questionnaire estimates symptom severity over the past six months; only a clinician can diagnose, and scores can be elevated by grief, medical illness or medications.
