What is attention deficit hyperactivity disorder (ADHD)?
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention and/or hyperactivity-impulsivity that significantly affects the functioning and development of a child.
Three major types of ADHD are:
- ADHD, Inattentive type;
- ADHD, Impulsive/hyperactive type; and
- ADHD, Combined type, which involves symptoms of both inattention and hyperactivity/impulsivity.
According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), children with inattentive ADHD display six or more of the following symptoms (at least five symptoms for adolescents above 17) for more than six months:
- Struggles to pay attention to details and makes careless mistakes;
- Has difficulty sustaining attention when engaging in daily activities, such as playing;
- Appears to be absent when spoken to, does not seem to listen;
- Struggles to follow instructions, complete chores, homework, etc;
- Struggles to organize tasks;
- Dislikes engaging in activities that require sustained mental effort, such as doing homework;
- Frequently loses objects for activities, such as pens, keys, books, etc;
- Is often distracted; and
- Is forgetful.
According to DSM-V, a child with the hyperactive/impulsive type of ADHD displays six or more of the following symptoms (at least five symptoms for adolescents above 17) for more than six months:
- Frequently fidgeting and tapping hands or legs;
- Leaving the seat when inappropriate, for instance, during class;
- Climbing when inappropriate;
- Unable to perform leisure activities quietly;
- Always being "on the go" (for instance, unable to stay still for long periods in classrooms or restaurants);
- Excessive talking;
- Often responds before the question is fully asked and does not wait for their turn to talk;
- Has difficulty waiting for their turn in general (e.g., in a queue); and
- Frequently interrupts others (e.g., during activities and conversations).
SNAP-IV Teacher and Parent Rating Scale - ADHD assessment
The SNAP-IV 26-item Teacher and Parent Rating Scale is a screening tool often used in clinical settings to measure ADHD symptoms in children aged 6 to 18. This SNAP-IV rating scale screens for symptoms of hyperactivity/impulsivity, inattention, and oppositional defiant disorder. The scale consists of three subsets:
- Inattention – This subset screens for symptoms related to difficulties sustaining attention, following instructions, organizing tasks and activities, forgetfulness, etc.
- Hyperactivity/Impulsivity – This subset screens for symptoms related to fidgeting, leaving a seat when inappropriate, inability to engage in leisure activities quietly, excessive talking, difficulty waiting for their turn, and interrupting when others are talking.
- Opposition /Defiance – This subset screens for symptoms related to the oppositional defiant disorder, such as refusing to act as asked for, being easily annoyed by others, blaming others for their mistakes, having an angry attitude, and being vindictive.

⚠️ Note, that you can not diagnose a child with ADHD by using just the SNAP-IV rating scale; don't hesitate to contact a healthcare professional if you suspect your child is displaying symptoms of ADHD.
How does the snap score calculator work?
Using the snap score calculator is relatively straightforward. For each statement, you need to select the point on the scale that you feel most appropriate in describing the assessed person.
In the end, the calculator will display the severity of symptoms in three subsets: Inattention, Hyperactivity/Impulsivity, and Opposition/Defiance.
The symptoms will be interpreted as either:
- Not clinically significant;
- Mild symptoms;
- Moderate symptoms; or
- Severe symptoms.
ADHD treatment for children
Although there is no cure for ADHD, there are many treatment options for improving the functioning and quality of life of children with ADHD. Some of the treatment options include:
- Stimulant medications such as methylphenidates and amphetamines; if you want to learn more about Adderall and its dosage, you can use Omni Adderall dosage calculator.
- Behavior therapy, such as play or talk therapy;
- Social skills training for improving social interactions; and
- Parent training and psychoeducation, for teaching parents skills necessary to assist their children to navigate social and academic life.
What scores indicate severe symptoms on the SNAP ADHD assessment?
According to the SNAP ADHD questionnaire, scores higher than 22 in the Inattention and Hyperactivity/Impulsivity subset and higher than 18 in the Opposition/Defiance subset indicate severe symptoms. However, keep in mind that SNAP-IV Teacher and Parent Rating Scale is just a screening tool, and you may need to consult with a healthcare professional for further assessment.
How do I interpret the Inattention subset of the SNAP-IV rating scale?
You can interpret Inattention subset of the SNAP-IV rating scale the following way:
- Sum the scores of the Inattention subset.
- Find which category your total score corresponds to in the table below:

Symptoms are not clinically significant
- That's all! Depending on your results, you can choose to pursue further assessment with a healthcare professional.

- ATTEX (Attention and Executive Function Rating Inventory);
- BRIEF (Behavior Rating Inventory of Executive Function);
