It aims to maximize sensitivity to detect as many potential cases as possible, with follow-up questions used to clarify at-risk responses. Scoring is completed in under two minutes, followed by guidance for low-, medium-, and high-risk outcomes, including referral for diagnostic evaluation and early intervention eligibility when indicated.","Modified Checklist for Autism in Toddlers, Revised, with Follow-Up  \n(M-CHAT-R/F)TM  \nDiana L.

The M-CHAT-R/F is available for free download for clinical, research, and educational purposes. Download of [the M-CHAT-R/F and related material is authorized from](the M-CHAT-R/F and related material is authorized from www.mchatscreen.com)[ ](the M-CHAT-R/F and related material is authorized from www.mchatscreen.com)[www.mchatscreen.com](the M-CHAT-R/F and related material is authorized from www.mchatscreen.com).  \nThe M-CHAT-R/F is a copyrighted instrument, and use of the M-CHAT-R/F must follow these guidelines:  \n(1) Reprints/reproductions of the M-CHAT-R must include the copyright at the bottom (􀂤 2009 Robins, Fein, & Barton) . No modifications can be made to items, instructions, or item order without permission from the authors.  \n(2) The M-CHAT-R must be used in its entirety. Evidence indicates that any subsets of items do not demonstrate adequate psychometric properties.  \n(3) Parties interested in reproducing the M-CHAT-R/F in print (e.g. , a book or journal article) or electronically for use by others (e.g. , as part of digital medical record or other software packages) must contact Diana Robins to request permission ([DianaLRobins@gmail.com](DianaLRobins@gmail.com)) .  \n(4) If you are part of a medical practice, and you want to incorporate the first stage M-CHAT-R questions into your own practice’s electronic medical record (EMR), you are welcome to do so. However, if you ever want to distribute your EMR page outside of your practice, please contact Diana Robins to request a licensing agreement.  \nInstructions for Use  \nThe M-CHAT-R can be administered and scored as part of a well-child care visit , and also can be used by specialists or other professionals to assess risk for ASD. The primary goal of the M-CHAT-R is to maximize sensitivity, meaning to detect as many cases of ASD as possible. Therefore, there is a high false positive rate, meaning that not all children who score at risk will be diagnosed with ASD. To address this, we have developed the Follow-Up questions (M-CHAT-R/F) . Users should be aware that even with the Follow-Up, a significant number of the children who screen positive on the M-CHAT-R will not be diagnosed with ASD; however, these children are at high risk for other developmental disorders or delays, and therefore, evaluation is warranted for any child who screens positive. The M-CHAT-R can be scored in less than two minutes. Scoring instructions can be downloaded from [http://www.mchatscreen.com](http://www.mchatscreen.com. Associated)[. Associated](http://www.mchatscreen.com. Associated) documents will be available for download as well.  \nScoring Algorithm  \nFor all items except 2, 5, and 12, the response “NO” indicates ASD risk; for items 2, 5, and 12, “YES”indicates ASD risk. The following algorithm maximizes psychometric properties of the M-CHAT-R:  \nLOW-RISK: Total Score is 0-2; if child is younger than 24 months, screen again after second birthday. No further action required unless surveillance indicates risk for ASD.  \nMEDIUM-RISK: Total Score is 3-7; Administer the Follow-Up (second stage of M-CHAT-R/F) to get additional information about at-risk responses.
