| dc.description.abstract | The General Aptitude Test Battery (GATB), a vocational test developed in 1947 by
the United States Employment Service (USES), is one of the most widely used and
researched instruments worldwide. A recent development important in improving
the GATB was the introduction o f a new computer administered version, the GATBCA
or GATB-Computerized Administration. Presently, there has been no research
conducted w ith the GATB-CA. Thus, the purpose of the present study was twofold:
(1 ) to compare the GATB-CA to the original GATB to test for equivalence in subject
test scores and item response speed (measured by the total number of items
completed) and (2) to investigate if scores from either of the GATB formats were
able to predict success in subjects obtained from an academic program of study.
Subjects consisted of 62 undergraduate students. The research involved a random
assignment counterbalanced design with all subjects completing both the
conventional and computerized GATB versions. Results showed that certain parts of
the GATB-CA were equivalent to the original GATB (subtests 6 and 7; aptitudes P
and S) while other portions were significantly different (subtests 1 and 4; aptitudes
G, Q, and V). Despite these differences, the GATB-CA was able to predict academic
success with essentially the same level o f confidence as the original GATB. Thus,
the GATB-CA was found to be closely related to but not equivalent to the original
GATB. | |
