This study examined the factor structure of the Detroit Tests of Learning Abilities, Fifth Edition (DTLA-5) using principal axis factoring, multiple factor extraction criteria, and the Schmid-Leiman orthogonalization procedures not utilized by test publishers. Results suggest that the publisher's six-factor structure model was over factored.…

This study examines the psychometric features of a General Aptitude Test-Verbal Part, which is used with assessments of high school graduates in Saudi Arabia. The data supported a bifactor model, with one general factor and three content domains (Analogy, Sentence Completion, and Reading Comprehension) as latent aspects of verbal aptitude.

Three studies of college students (n=178, 129, and 96) evaluated the reliability and validity of the Assessment of Attributions for Career Decision-Making instrument. Factor analysis supported a three-factor structure. The instrument demonstrated adequate internal consistency, test-retest reliability, and construct, criterion, and incremental…

The present study suggests that although the reliability of an academic aptitude test given under formula-score condition can be increased substantially through empirical option weighting, much of the increase is due to the capitalization of the keying procedure on omitting tendencies which are reliable but not valid.

Fourteen estimates were made of "g" (general cognitive ability) from the normative sample of a multiple-aptitude test battery with a weighted sample representing 25,409,193 men and women. The methods, which included principal components, unrotated principal factors, and hierarchical factor analysis, are equivalent for this test. (SLD)

Presented is an investigation of the item and factor characteristics which make up Forms 8, 9, and 10 of the Armed Services Vocational Aptitude Battery (ASVAB). Data on the ASVAB forms were collected from mulitary enlistment applications at 20 Armed Forces Examining and Entrance Stations. Item and factor analyses were conducted on samples equated…

An experimental test battery consisting of several tests that measure aspects of artistic judgment was administered to over 1,600 clients of the Johnson O'Connor Research Foundation. The battery consisted of the Visual Aesthetic Sensitivity Test (VAST) of K. O. Gotz (1981); the Design Judgment Test (DJT) of M. Graves (1948); and two tests…

The selection of an appropriate test battery is based on its content and applicability to the vocational trainee population. This report describes the testing of a national sample of U.S. high school students with an established version of Armed Services Vocational Aptitude Battery (ASVAB), and a new, enlarged version of the same test battery.…

The original "Bayley Scales of Infant Development" (BSID) (Bayley 1969) have been among the most popular measures of performance and aptitude of infants. In the present study the reliability and construct validity of mental and motor scores on the revised Bayley Scales of Infant Development-II (BSID-II) were investigated. A national…

The keylist format (rather than the conventional multiple-choice format) for item presentation provides a machine-scorable surrogate for a truly free-response test. In this format, the examinee is required to think of an answer, look it up in a long ordered list, and enter its number on an answer sheet. The introduction of keylist items into…

Four new versions of an acoustic structuring test were developed, administered, and analyzed in order to produce better tests and to contribute to better understanding of the abilities measured by these tests. The tests consist of tape recordings of patterns of musical notes played on an electric organ or an acoustic guitar. Item analyses and…

As a measure of musical aptitude, a new 90-item Pitch Discrimination Test was developed, and its internal structure was examined. Each of the three sections of the test measures an individual's aptitude for pitch discrimination in a different frequency range using square-wave tones generated by a personal computer. A total of 1,303 examinees,…
