However, if you ever want to distribute your EHR 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 the likelihood for autism. The primary goal of the MCHAT-R is to maximize sensitivity, meaning to detect as many cases of autism as possible. Therefore, there is a high false positive rate, meaning that not all children who score at increased likelihood will be diagnosed with autism. 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 autism; however, these children have an increased likelihood 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 For all items except 2, 5, and 12, the response “NO” indicates elevated likelihood of autism; for items 2, 5, and 12, “YES” indicates elevated likelihood of autism. The following algorithm maximizes psychometric properties of the M-CHAT-R:  \nLOW-Likelihood: Total","cbCairiVc33WWrE5","https://ap.wps.com/l/cbCairiVc33WWrE5","pdf",514375,1,25,"English","en",105,"# Instructions for Use\n## Screening stages and purpose\n## Scoring approach and time\n# Scoring Algorithm\n## Response mapping for items 2, 5, and 12\n## Low-likelihood pathway\n## Moderate-likelihood pathway\n## High-likelihood pathway\n# Permissions for Use of the M-CHAT-R/F\n## Copyright and reprint rules\n## Required use conditions\n## Requests for reproduction or licensing","[{\"question\":\"What is the purpose of the M-CHAT-R/F screening tool?\",\"answer\":\"It is a 2-stage parent-report instrument used to assess the likelihood of autism.
