| Abstract: | The success of early intervention programs created to prevent children from experiencing reading failure is contingent upon the accurate identification of children at risk for reading difficulties. The present study assessed 291 first graders (M Age = 79.7 months; 54.9% female, 45.1% male) on reading, intelligence, and phonological processing at the beginning and end of the academic year to determine the accuracy of three different approaches to identification. The first procedure used the calibration data from a reference group's discriminant analysis, the second simply determined the children who scored below the mean on all of the reading and phonological variables (Simple Computation), and the last used a weighting system (Complex Computation). The children were classified into good and poor reading groups based on composite reading scores determined by averaging their standard scores on Word Identification, Word Attack, and Passage Comprehension of the Woodcock Reading Mastery Test-Revised (Woodcock, 1987) at the end of the year. The poor readers were further classified, based on their scores on the Peabody Picture Vocabulary Test-Revised (Dunn & Dunn, 1981) into groups containing children who had reading difficulties (RD) and children whose reading abilities were commensurate with their intelligence (intelligence commensurate, IC). Although all of the procedures provided relatively accurate identification, 80.2%, 87.3%, 89.7%, for the discriminant analysis, Simple Computation, and Complex Computation, respectively, the last procedure provided the best overall accuracy with the smallest percentage of false negatives (6.2%). |
