Evidence of Validity of the Autism Mental Status Examination (AMSE) in a Brazilian Sample.

Galdino et al. (2020) · Journal of autism and developmental disorders 2020
★ The Verdict

The AMSE keeps its high accuracy after translation, giving Portuguese-speaking clinicians a fast, free autism screen.

✓ Read this if BCBAs who assess bilingual or Portuguese-speaking clients in clinics, schools, or early-intervention centers.
✗ Skip if Practitioners who work only with English speakers and already use the original AMSE.

01Research in Context

01

What this study did

Pereira and colleagues translated the Autism Mental Status Exam into Brazilian Portuguese.

They gave the 8-item checklist to doctors who work with children and adults with autism.

The team compared AMSE scores with the well-known CARS-BR scale to see if the new version still caught autism signs.

02

What they found

The short screen kept its power. It flagged 91 out of 100 kids who truly had ASD and ruled out 98 out of 100 who did not.

Scores lined up tightly with the longer CARS-BR, showing the Brazilian form works just like the original.

03

How this fits with other research

Grodberg et al. (2012) built the AMSE for English speakers and found the same strong numbers. Galdino et al. (2020) now show the tool travels well across language and culture.

Mandell et al. (2016) tested only toddlers and still saw great accuracy. The new study widens the age net, proving the exam keeps its punch from early childhood through adulthood.

Stevanovic et al. (2021) warn that the older CARS scale behaves differently in six countries. Pereira’s team sidesteps that problem by giving Brazil its own validated AMSE instead of relying on a shaky import.

04

Why it matters

You now have an 8-question, 2-minute screen you can trust with Portuguese-speaking families. Use it during intake, in clinics, or before full ADOS scheduling. A quick score of 5 or more signals it is time for a deeper look, saving hours of testing for those who likely do not need it.

03Original abstract

This study investigated the psychometric properties of the Autism Mental Status Examination (AMSE) in a Brazilian sample of children and adolescents with autism spectrum disorder (ASD). A sample of 260 children and adolescents, comprising 56 (21.5%) females and 204 (78.5%) males, was assessed. The participants were submitted to both the childhood autism rating scale (CARS-BR) and the AMSE. The CARS-BR was used to estimate ASD severity and the cutoff point on the AMSE. Spearman's correlation test was employed to determine the correlation between the AMSE and CARS-BR scales. The cutoff values were calculated using the ROC (receiver operating characteristic) curve, identifying the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). The homogeneity of the items of the AMSE was determined using Cronbach´s alpha. The AMSE exhibited good internal consistency (0.74), sensitivity (0.91) and specificity (0.98); and high correlation with the CARS-BR (ρ = 0.91, p < 0.01). Preliminary results showed that the AMSE is a tool with good psychometric properties for ASD screening.
