Construct and validation of a learning disability diagnostic test in preschool children

The researcher's test consists of nineteen factors and has two parts: audio and visual; its content validity was confirmed by psychology professors and then a sample of 206 pre-school students was performedAccording to the calculations, Pearson correlation coefficient between the two-part questionnaire was r = 0.81 in the auditory comprehension section and r = 0.79 in the visual comprehension section.. In order to determine the validity of the structure and the components of the questionnaire, the main components analysis method was used with varimax normalized rotation. The most important factor in the visual-spatial perception area is the symbolization, and in the auditory part it is memory. Independent t-test was used to assess discriminant validity. Results showed that there is a significant difference between the mean scores of students with learning disabilities and normal in the learning disability test. In order to check the validity of this study, a checklist of learning disability that was completed at the same time by the mothers was used. The results showed that there is a significant relationship between the two tests. According to the validity and reliability, the learning disability test is a tool that can be used by learning and counseling centers.
