Modified Checklist For Autism In Toddlers, Revised With Follow-Up (MCHAT-R/F)

The Modified Checklist for Autism in Toddlers, Revised with Follow-Up (MCHAT-R/F; Robbins, Fein, & Barton, 2009), designed to screen for autism in toddlers from 16 to 30 months, was developed for use during well-child checkups.

Overview

It is a two-step autism-screening tool. The first step is a 20-item yes/no parent/caregiver questionnaire that yields Low, Medium, or High Risk classifications. The second step of the process is a follow-up questionnaire, given for a child found to be at medium risk. The follow-up questionnaire consists of 20 pass/fail items used to gather further information for classification into High Risk or Low Risk categories.
