The developmental dyslexia scale for standard mandarin: A study among early primary students
Background
Developmental dyslexia (DD) is a prevalent neurodevelopmental disease that poses challenges in both early intervention and long-term development for children with DD. However, there is a lack of a standardized and comprehensive tool for the diagnosis of DD in Mainland China.
Aim
To develop a standardized tool (i.e., Developmental Dyslexia Scale for Standard Mandarin [DDSSM]) for the diagnosis of DD in Mainland China and evaluate its reliability and validity.
Methods and procedures
DDSSM consists of 10 subtests. The initial draft was created after Delphi expert consultation, and the final version was revised to improve discriminability with a pilot study involving 450 children from grades 1–3. The reliability and validity were then confirmed with 53 children from grades 1–2.
Outcomes and results
The Delphi expert consultation demonstrated that the expert panel had good authority, and that all agreed on the subtest setup. The DDSSM exhibited great internal consistency. Confirmatory factor analysis revealed that the model aligns with the theoretical structure (P > 0.05, χ2/df < 2.00, root-mean-square error of approximation (RMSEA) < 0.08, comparative fit index (CFI) > 0.90, TLI > 0.90). The Dyslexia Checklist for Chinese Children and children’s academic performance agreed well with the DDSSM.
Conclusions and implications
The DDSAM is reliable and valid for assessing and diagnosing DD in Standard Mandarin-speaking primary school children from grades 1–2.
What this paper adds?
Although a number of scales and tools have been proposed for assessing developmental dyslexia (DD) in Chinese, there is still a lack of diagnostic tools for Mandarin Chinese in Mainland China. In this study, we developed one of the most comprehensive diagnostic tools for DD in Mandarin Chinese for lower graders. We included visual-spatial attention (VA) and compounding awareness (CA), two tests that have been recently suggested as reliable measures for identifying DD in the Chinese language. This assessment tool has been verified for robust reliability and validity.
This study also provided confirmation of the core deficits of DD in Chinese, which were orthographic awareness (OA). In addition, VA, rapid automatized naming (RAN) and morphological awareness (MA) were found to be the most important cognitive abilities for word reading in Chinese lower graders in this study.
期刊介绍：
Research In Developmental Disabilities is aimed at publishing original research of an interdisciplinary nature that has a direct bearing on the remediation of problems associated with developmental disabilities. Manuscripts will be solicited throughout the world. Articles will be primarily empirical studies, although an occasional position paper or review will be accepted. The aim of the journal will be to publish articles on all aspects of research with the developmentally disabled, with any methodologically sound approach being acceptable.
