The observer rates each item on what kind of scale in PEACH/TEACH?

• A. A three-point scale: Never, Sometimes, Always.
• B. A 0-4 scale based on estimated percentage of time the child displays the behavior.
• C. A 0-10 numeric scale.
• D. A 1-5 Likert scale from Never to Always.

Answer: (B)

The key idea is that PEACH and TEACH quantify how often a child uses listening/communication behaviors in daily life by tying each observed item to a proportion of time. Each item is scored on a 0-4 scale that corresponds to estimates of percent of time the behavior is displayed: 0 means the behavior isn’t observed at all, 1 ≈ 25% of the time, 2 ≈ 50%, 3 ≈ 75%, and 4 ≈ 100%. This gives a consistent, interpretable measure of daily performance across items and observers. This time-based, percentage-linked scoring helps capture real-world usage rather than just whether a behavior happens or how strongly it is performed. If a child shows a behavior about half the time in typical daily settings, you’d place that item in the middle of the scale. Other scales like a simple three-point scale, a 1-5 Likert, or a 0-10 numeric scale don’t align with how these tools assess everyday frequency and can obscure the actual proportion of time the behavior occurs.
