Introduction
The Malay Autism Spectrum Quotient, Children’s Version (AQ-Child) is a translated and condensed instrument initially designed to screen for Autism Spectrum Disorder (ASD) in children aged 6 to 12 years. This study aimed to evaluate the reliability and validity of the translated Malay version of the AQ-Child. By engaging parents of 700 children—47 diagnosed with ASD and 653 typically developing—through special education and mainstream primary schools, the study sought to assess the questionnaire's psychometric properties, including its internal consistency, factor structure, and appropriate cut-off scores.
Sensitivity and Specificity in Screening
One significant finding from the study was the performance of the Malay AQ-Child in terms of sensitivity and specificity. The analysis revealed a cut-off score of 63 for the screening tool, yielding a sensitivity of 93% and specificity of 99%. This finding suggests that the AQ-Child is highly effective at distinguishing between children diagnosed with ASD and those who are typically developing. The study utilized receiver operating characteristic (ROC) analysis to evaluate the instrument further, which affirmed its capability as a reliable screening instrument for early detection of ASD in the Malaysian context.
Conclusion
The results indicate that the Malay AQ-Child is a reliable and valid screening tool that can significantly aid in the early detection of Autism Spectrum Disorder among children in various educational settings. The successful validation of this instrument underscores its usefulness for local practitioners and educators seeking to implement effective screening measures for ASD. The study's findings pave the way for future research, emphasizing the importance of culturally appropriate diagnostic tools and the need for continued efforts to enhance support for children with ASD and their families within Malaysia.
