{{ assessmentHydrationError || 'This assessment session could not be evaluated.' }}
Attention-deficit/hyperactivity disorder (ADHD) is assessed from a pattern of attention, organization, activity, and impulse-control difficulties, together with their history and effect on daily life. No short self-report score can establish that pattern by itself. Similar experiences can occur with poor sleep, stress, anxiety, depression, substance use, medication effects, learning differences, or physical illness.
The preliminary IPIP ADHD syndrome scale is a 12-item adult research measure associated with Span and colleagues' 2002 work. Its statements ask how accurately everyday tendencies describe the respondent, such as forgetting things, losing focus, or acting without enough forethought. All 12 statements point in the same scoring direction, so stronger endorsement raises one continuous raw score.
- Research score
- A sum that describes endorsement of this particular item set.
- Diagnostic assessment
- A broader evaluation of symptoms, impairment, onset, persistence, settings, history, and alternative explanations.
- Clinical cutoff
- A validated boundary that separates screening outcomes. The IPIP source does not provide one for this preliminary scale.
A higher total means that more of the listed ADHD-related tendencies were endorsed as accurate. It does not show whether the experiences began in childhood, occur in more than one setting, cause meaningful impairment, or are better explained by something else. Those questions are central to diagnosis and treatment planning.
Use the result for structured reflection, education, or research preparation. It must not be used to decide diagnosis, medication, accommodation, hiring, school eligibility, or whether someone does or does not need professional help.
How to Use This Tool:
Answer for how you generally are now, using the same frame of reference across all 12 statements.
- Select Start assessment, then rate each statement from Very inaccurate to Very accurate.
- Choose the answer that reflects your usual pattern rather than one unusually good or difficult day. Select Continue only after the current response matches what you intended.
- Complete all 12 statements. If the result is not available, return to the unanswered statement and add the missing response.
- Read the IPIP ADHD-related tendencies raw score as a continuous research total, then review individual answers when a result feels surprising.
Interpreting Results:
The possible total runs from 12 to 60. Higher values mean stronger endorsement of the 12 listed tendencies; lower values mean weaker endorsement. There are no low, moderate, high, positive, or negative bands in the source, so the number should remain on its full continuum.
- Do not compare the score with an invented midpoint or internet cutoff.
- Do not treat a high value as an ADHD diagnosis or a low value as a rule-out.
- When the result matters, pair it with examples of impairment, duration, settings, developmental history, sleep, mood, substance use, and other possible causes.
- For research comparisons, use a suitable comparison sample and the same wording, response scale, and administration conditions.
Technical Details:
The instrument contains 12 positively keyed statements. Each raw response is already the keyed item score, from 1 for Very inaccurate through 5 for Very accurate. A complete result therefore needs no reverse scoring, weighting, normalization, or threshold rule.
Formula Core:
The raw total S is the sum of the 12 keyed responses xi.
| Scoring element | Exact rule |
|---|---|
| Item scale | Very inaccurate = 1, Moderately inaccurate = 2, Neither inaccurate nor accurate = 3, Moderately accurate = 4, Very accurate = 5. |
| Key direction | All 12 items are positive-keyed; no response is reversed. |
| Aggregation | Sum all 12 item scores with weight 1. |
| Valid total | 12 to 60 points, inclusive. |
| Missing response | No total is reported until every item has a valid response. |
| Precision | The total is an integer; no rounding is applied. |
| Interpretive bands | None. The displayed result remains a continuous raw score. |
For example, six responses scored 4 and six scored 3 produce 42 points. The arithmetic is exact, but 42 has no source-defined diagnostic meaning or severity label.
Limitations and Privacy:
This preliminary adult self-report scale does not assess diagnostic criteria, childhood onset, cross-setting symptoms, impairment, observer reports, or alternative explanations. It is informational and not a substitute for professional diagnosis or treatment.
- Responses stay in memory during the current session; no telemetry or server scoring is used.
- An optional copied result link contains all 12 raw responses in its URL fragment. The fragment is not encrypted or access-controlled.
- Restarting clears the in-memory session and removes the shared fragment.
- Share a completed result only with someone who should be able to recover the item-level answers.
FAQ:
What score indicates ADHD?
No score on this preliminary IPIP scale establishes ADHD. The source provides neither a diagnostic cutoff nor individual severity bands.
Why is there no reverse scoring?
All 12 source items are positive-keyed. Greater descriptive accuracy therefore contributes a larger score to every item.
