A Multi-Trait, Multi-Method Analysis of the Bayesian Screening Instrument and Test Battery for LD Adolescents.
Alley, Gordon R.; And Others
The reliability and validity of the Modified Component Disability Checklist were examined with five secondary learning disabled (LD) teachers, 21 low achieving students, and 21 LD students in grades 7, 8, and 9. During Phase I, teachers matched the component disability to the target behavior; and in Phase II teachers were told to judge each target behavior on the basis of five criteria--importance, frequency of occurrence in LD students, frequency of occurrence in nonLD students, accessibility to observation in a classroom setting, and the grade level at which the behavior becomes important when differentiating LD from non LD students. The Modified Component Disability Checklist was found to be a reliable screening measure, expecially at grades 8 to 12. In Phase II, 21 LD and 21 low achieving junior high school students were rated by the Modified Checklist of Learning Difficulties and the Test Battery for Learning Problems. Three conclusions were reached: (1) the Modified Checklist is generally a stable measure, (2) the component disabilities are relatively independent, and (3) the two measures are moderately related but appear to measure different aspects of the component disabilities. The series of three studies led to several assumptions, including that there are unique clusters of behavioral manifestations that can be used to identify LD adolescents. Tables with statistical data are offered, and a copy of the Checklist of Academic Problems is appended. (SB)
