VALIDATION OF STANFORD-BINET INTELLIGENCE SCALE - 4TH EDITION ABBREVIATED BATTERIES WITH COLLEGE-STUDENTS

This study investigated the relationship between the Stanford-Binet In telligence Scale: Fourth Edition (SB:IV) abbreviated batteries and the complete battery among a group of college students to determine the s uitability of SB:IV short forms in educational planning and counseling contexts when an ability estimate is needed. A sample of 38 college s tudents was administered the full battery SB:IV, and scores for four a bbreviated batteries were extracted from the complete battery accordin g to instructions in the test manual. The four abbreviated batteries w ere SF2 (Vocabulary and Pattern Analysis), SF4 (SF2 plus Bead Memory a nd Quantitative), SF6a (SF4 plus Memory for Sentences and Comprehensio n), and SF6b (SF4 plus Memory for Digits and Comprehension). Analyses revealed that all short-form SASs were significantly lower than the Co mposite SAS derived from the complete battery. Correlations between th e complete and short forms were all highly significant. Approximately one third of the sample showed discrepancies of at least three standar d errors of measurement between the short-form and complete-battery Co mposite SAS. These findings suggest a lack of comparability between sh ort-form and complete-battery SASs on the SB:IV. Further implications for the validity of these abbreviated batteries and future areas of re search are discussed.
