Insights
The electronic Modified Checklist for Autism in Toddlers (M-CHAT) significantly reduced false autism screening results and improved parent satisfaction compared to the paper version.
Area of Science:
- Pediatric screening tools
- Autism spectrum disorder diagnostics
- Digital health applications
Background:
- The Modified Checklist for Autism in Toddlers (M-CHAT) is a standard clinical screening tool for autism spectrum disorders.
- Paper-based M-CHAT implementation faces challenges, particularly with follow-up questions.
Purpose of the Study:
- To evaluate the effectiveness of an electronic M-CHAT compared to a traditional paper format.
- To assess parental satisfaction with electronic versus paper M-CHAT administration in an outpatient setting.
Main Methods:
- A prospective study utilized an electronic M-CHAT on iPads.
- A retrospective review of paper M-CHATs administered 6 months prior served as the control group.
- 176 participants completed the electronic M-CHAT, and 197 paper M-CHATs were analyzed.
Main Results:
- The electronic M-CHAT format showed a significantly lower frequency of children identified at risk for autism (3%) compared to the paper version (11%).
- Parental satisfaction was exceptionally high, with 99% rating the electronic experience as "good" or "excellent."
Conclusions:
- The electronic M-CHAT format demonstrated improved accuracy by reducing both false positive and false negative screening results.
- Digital implementation of the M-CHAT enhances user experience and parental satisfaction.
Background:
The Modified Checklist for Autism in Toddlers (M-CHAT) is a screening tool for autism spectrum disorders in the clinic. However, the follow-up questions in the M-CHAT are difficult to implement on a paper format.
Objective:
To compare the effectiveness of the M-CHAT on an electronic format versus paper format in an outpatient clinic setting. Methods. A prospective study used electronic M-CHAT on the iPad. A retrospective review of paper M-CHATs 6 months prior to implementation was used as the comparison group.
Results:
A total of 176 participants completed the electronic M-CHAT format and 197 paper M-CHATs were retrospectively reviewed. The electronic format (3%) resulted in a significant difference in the frequency of children found to be at risk for autism compared with the paper version (11%); 99% of parents rated the experience as "good" or "excellent."
Conclusion:
The electronic format lowered both false at-risk screens and false not-at-risk screens and had higher parental satisfaction.
