How Is The MCHAT Administered?

The MCHAT consists of two sections: the first nine items are questions asked to the parents, and the last five items are observations made by the primary health care worker. The key items look at behaviors which, if absent at 18 months, put a child at risk for a social-communication disorder.

These behaviors are joint attention, including pointing and looking to where a parent is pointing and pretend play, such as pretending to pour tea from a toy teapot.
