Child 16-30 months, worried about autism? Start with M-CHAT-R
M-CHAT-R is the most widely used toddler autism screen, for ages 16-30 months. The parent who knows the child best answers 20 yes/no items, scored by risk: 0-2 low, 3-7 medium, 8-20 high. Its role is early detection — a positive screen is 診断ではありません but a prompt to see a child-health or developmental-behavioral professional soon. Free; scored locally.

よくある質問
高リスクは自閉症の診断を意味しますか？
No. M-CHAT-R is a screen that indicates risk level, 診断ではありません. Even at high risk, a developmental-behavioral or child-health professional must confirm with an evaluation, structured interview and assessment. Early assessment avoids missing the window for support.
16か月未満または30か月超でも使えますか？
M-CHAT-R is validated for 16-30 months. Outside that range results may be unreliable; consult a child-health or developmental-behavioral pediatrician for a more suitable assessment.
中リスクの場合はどうすればよいですか？
In the proper workflow, medium risk needs a follow-up interview (M-CHAT-R/F), usually done by a professional. See a clinic for clarification rather than reassuring or alarming yourself on this result alone.
