Analysis

The Swanson, Nolan, and Pelham Scale, Version IV – Teacher Form (SNAP-IV Teacher Form) is an assessment tool used by teachers to observe and record symptoms of ADHD (Attention-Deficit/Hyperactivity Disorder) and ODD (Oppositional Defiant Disorder) in students. The scale includes statements that evaluate levels of inattention, hyperactivity/impulsivity, and behavioral problems.

Objective

The goal of the SNAP-IV Scale is to provide teachers with a reliable and valid tool for observing and evaluating symptoms of ADHD and ODD in students, in order to support diagnosis and intervention.

Calibration

The SNAP-IV Scale includes 26 statements that assess symptoms of ADHD and ODD using a 4-point Likert scale (“not at all,” “just a little,” “quite a bit,” “very much”). Teachers are asked to rate the frequency of symptoms they have observed in their students over the past six months. The statements cover symptoms of inattention (e.g., “Does not seem to listen when spoken to directly”), hyperactivity/impulsivity (e.g., “Has difficulty remaining seated when expected”), and oppositional behavior (e.g., “Often loses temper”).
