ABSTRACT

Although reading is one of the important skills to achieve during the early school age years, children with dyslexia have difficulty in reading. To develop and examine the suitability of a dyslexia-diagnosis test, this study conducted a preliminary validation study with 263 students including general students, reading under- achievement students, reading disabilities students. The 11 testlet, 24 subtests and test items were developed through analyzing domestic and overseas preceding researches on reading including dyslexia, and dyslexia-related diagnosis tests. As a result of examining the validity of the test developed in this study, inter-item consistency was high at .815 and standard error of measurement was low form .328 to 2.025. In terms of validity, content validity was established by domestic and overseas preceding studies and test-analysis. As a result of conducting correlation analysis, confirmative factor analysis, and analysis comparing differences among groups, the developed diagnosis test turned out to be appropriate to diagnose students who show difficulty in reading including dyslexia. Based on such results, some discussions and implications were offered for standardization of dyslexia- diagnosis test.
