Using the modified checklist for autism in toddlers in a well-child clinic in Turkey: adapting the screening method based on culture and setting.
Have nurses ask M-CHAT questions aloud instead of handing parents the form—this simple change cut false positives and lifted PPV to 75% in Turkish clinics.
01Research in Context
What this study did
Doctors in Turkey gave the M-CHAT to parents of toddlers during regular check-ups. Instead of letting moms and dads fill out the paper alone, nurses asked each question out loud and wrote the answers. This small change aimed to fit the tool to Turkish families who may read less or feel shy with forms.
What they found
Talking through the M-CHAT lifted its positive predictive value to 75%. That means three out of every four kids who failed the screen truly had autism or developmental delay. Fewer false alarms saved families extra trips and worry.
How this fits with other research
Nygren et al. (2012) tried a different tweak in Sweden. They kept parent self-rating but added a quick nurse check for joint attention. Their PPV hit 90%, showing both small changes work yet in different ways.
Ruel et al. (2021) looked at M-CHAT scores in typical 18-month-olds. Higher scores linked with lower language skills even when autism was not present. This warns us that a fail does not always equal autism; language or shyness can also lift the score.
Zamora et al. (2016) showed that culture matters. They used Spanish flyers and flexible times to pull Latino families into autism studies. Like the Turkish team, they proved that matching method to culture boosts family trust and data quality.
Why it matters
You can copy the interview style anywhere parents struggle with forms. Ask each M-CHAT item aloud while the family waits. Jot the answers yourself. This five-minute habit can cut false positives and build rapport. Remember that a fail may still need a language check, not just an autism referral.

03Original abstract
We aimed to adapt the Modified Checklist for Autism in Toddlers to Turkish culture. The Modified Checklist for Autism in Toddlers was filled out independently by 191 parents while they were waiting for the well-child examination of their child. A high screen-positive rate was found. Because of this high false-positive rate, a second study was done in which the Modified Checklist for Autism in Toddlers was administered by health-care staff in a short interview with two groups of parents. The first group (the high-risk group) comprised 80 children aged 18-36 months, who were initially diagnosed with pervasive developmental disorders. The second group (the low-risk group) comprised 538 children of the same age, who were followed regularly by the well-child clinic. Two screen positives were found in the low-risk group. These two children, a random sample of 120 children from the low-risk group, and all the high-risk group were invited to a clinical evaluation. The diagnostic power of the Modified Checklist for Autism in Toddlers was assessed against clinical diagnosis and the Childhood Autism Rating Scale. The positive predictive value of the Modified Checklist for Autism in Toddlers was found to be 75%. Our findings led us to conclude that the Modified Checklist for Autism in Toddlers is a useful tool in Turkey for screening of pervasive developmental disorders in primary care, but in our culture, it is completed more accurately when health-care personnel ask the parents the questions. This study shows that Modified Checklist for Autism in Toddlers screening should be adapted based on culture and setting.
