Glossary Term

Dichotomous Item

Two opposite response options (A vs. B). Ideal for ages 4–8 in BPI/CHAT-E formats to reduce complexity.

A dichotomous item offers two contrasting statements or choices. For young children, this simplifies processing and reduces guessing across long Likert scales.

Example

Puppet A: “I like to play with other kids.”
Puppet B: “I like to play by myself.”

The child chooses the puppet that is more like them. See BPI and CHAT-E.
