Türkçe

Early diagnosis of autism spectrum disorder and planning interventions appropriate to individual needs are essential for the development of individuals. In this process, valid and reliable assessment tools are critical for diagnosis accuracy and the effectiveness of interventions. This review aims to present information on good practice for selecting assessment tools, preparation for the data collection process, data collection, analysis, and reporting stages to support valid and reliable screening and diagnosis processes in evaluating autism spectrum disorder. In this context, assessment tools used in the screening and diagnosis processes of autism spectrum disorder were examined in the context of validity and reliability, the criteria to be considered in selecting these tools were emphasized, and measurement errors encountered in the application processes were focused on. Suggestions are presented to minimize the impact of measurement errors. This study is thought to guide practitioners involved in the evaluation process of autism spectrum disorder.
