Abstract

The Social Responsiveness Scale (SRS) has been validated in high-income countries but not yet in low- and middle-income countries. We aimed to assess the reliability of the SRS in a community sample and its validity to discriminate between children with and without autism spectrum disorder (ASD) in Vietnam. We used a three-phase study: piloting the translated SRS, reliability testing, and validation of the SRS in 158 Vietnamese caretakers and their children (ages 4–9 years). We examined reliability, validity and sensitivity, and specificity to ASD diagnosis. We applied receiver operator characteristic (ROC) analysis to determine optimal cutoff scores discriminating the children with ASD from those without ASD. We also assessed the performance of the SRS short form. We found that reliability was good with high internal consistency (0.88–0.89), test–retest reliability (0.82–0.83), sensitivity (93%), and specificity (98%) for identification of children with ASD. The ROC curves were similar for total raw score and total T-score, with the area under the curve (AUC) values reaching 0.98 and the optimal cutoff of 62 for raw scores and 60 for T-scores. The SRS short form also performed well in distinguishing children with ASD from children without ASD, with high AUC (0.98), sensitivity (90%), and specificity (98%) when using a raw score of 15 as a cutoff. In conclusion, the translated and culturally adapted SRS shows good reliability, validity, and sensitivity for identification of children with ASD in Vietnam. Both SRS long and short forms performed adequately to discriminate between children with and without ASD. Autism Res 2019, 00: 1–13.
