Short Form Estimation of K-ABC Sequential and Simultaneous Processing for Research and Screening

Abstract

Used data from the Kaufman Assessment Battery for Children (K-ABC) standardization sample to develop short forms of the K-ABC Sequential Processing (SEQ) and Simultaneous Processing (SIM) scales for ages 4 through 12 1/2. Using five quantitative and qualitative criteria, we selected the best SEQ dyad and the best SIM dyad and triad. The preferred SEQ short form for screening and research purposes at ages 4 and older contains the Number Recall and Word Order subtests. The preferred SiM short-form triad combines Gestalt Closure, Triangles, and Matrix Analogies (at age 4, Magic Window substitutes for Matrix Analogies). A SIM dyad composed of Gestalt Closure and Triangles was selected fcr the entire 4- to1 12%-year age range.
