摘要

Purpose

This study aims to evaluate the validity and reliability of the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) in a cohort of Chinese toddlers aged 18 to 36 months.

Methods

Screening was conducted on toddlers aged 18 to 36 months, encompassing those with ASD, language impairments, developmental delays, and typical development. Evaluations were performed using the Diagnostic and Statistical Manual of Mental Disorders (5th ed), the Autism Diagnostic Observation Schedule-2, and the Modified Checklist for Autism in Toddlers. A random sample of 25 toddlers underwent a follow-up assessment with the RITA-T two weeks later. Critical values were determined based on the sensitivity, specificity, positive and negative predictive value of the RITA-T total score in differentiating ASD diagnoses.

Results

A total of 114 toddlers were enrolled in the study. The optimal cut-off score for the RITA-T in screening for ASD was determined to be 16, yielding a sensitivity of 0.918 and a specificity of 0.981, with an area under the receiver operating characteristic (ROC) curve of 0.961 (95% CI: 0.924–0.998, p < 0.001). Additionally, the scale exhibited strong internal consistency (Cronbach’s α = 0.828), high test-retest reliability (Spearman’s rho coefficient = 0.962, p < 0.01), and excellent inter-rater reliability (ICC = 0.975, 95% CI: 0.970–0.979, p < 0.001).

Conclusion

The Chinese version of the RITA-T is a robust instrument for the early identification of ASD and is highly applicable for early screening efforts in China.
