How this questionnaire works and where it comes from
The SNAP-IV 26-item parent form organizes observations into three raw subscale scores: inattention (items 1–9), hyperactivity/impulsivity (items 10–18), and oppositional behavior (items 19–26). Each response is scored from 0 to 3. The scores describe reported behavior and cannot diagnose ADHD or another condition.
Subscale example
If all nine inattention items are rated ‘Just a Little’ (1), the inattention raw score is 9 out of 27. The result should be considered with concrete examples and observations from more than one setting, such as home and school.
Source instrument and scoring reference are linked for verification. This site is not affiliated with OHSU or the instrument authors. The Spanish form on this site is an editorial translation of the 26-item structure, not a separately validated Spanish edition. Wording can vary from the linked English form.
Original context questions have their own timeframe and are not added to the standard score.
This report helps with reflection, support planning and conversations. A diagnosis needs a professional assessment that considers history, context and daily impact.
Common questions
Can this test diagnose my child?
No. This is a screening tool, not a diagnostic test. Think of it as a first step to reflect on patterns and decide whether to seek a professional evaluation. Only a qualified professional can provide a full evaluation and, if appropriate, a diagnosis.
What is the SNAP-IV?
The SNAP-IV (Swanson, Nolan, and Pelham, Version IV) is a widely used parent/teacher rating scale developed by Dr. James Swanson and colleagues. It has been used in many research studies and helps capture patterns in inattention, hyperactivity, impulsivity, and related behaviors in kids and teens.
What age range is this for?
This assessment works best for ages 6-18. For younger kids (under 6), attention difficulties can be hard to separate from normal developmental behavior, so professional evaluation is especially important. For teens, some questions need age-appropriate interpretation—for example, 'runs and climbs excessively' might show up differently in adolescents than in younger kids.
Should teachers complete this too?
Teacher input can be very helpful. Kids often behave differently at school than at home, so both perspectives can give a more complete picture. If you move forward with an evaluation, teacher observations are often part of the process.
How should I use the oppositional behavior score?
Use the raw subscale score to organize which behaviors were observed and how often. This site does not assign a severity label or diagnose a condition from that score. Concrete examples from home and school are more useful for a qualified evaluation than the number alone.
