The Detroit Tests of Learning Abilities–Fifth Edition (DTLA-5) is the oldest and most venerable of the tests of specific cognitive abilities. The figure below illustrates the DTLA-5 test structure.
The test includes 12 subtests: Humanities/Social Studies, Science/Mathematics, Word Opposites, Word Associations, Geometric Matrices, Geometric Sequences, Sentence Imitation, Word Span, Design Reproduction, Reversed Letters, Trail Making, and Rapid Naming. The results of the subtests can be combined to form 9 composites.
Six of these composites represent different cognitive subdomains (Acquired Knowledge, Verbal Comprehension, Nonverbal Problem Solving, Verbal Memory, Nonverbal Memory, and Processing Speed; two of these composites represent larger, important cognitive domains (Reasoning Ability and Processing Ability). One global composite is formed by combining the results of all 12 of the DTLA-5 subtests and represents general cognitive ability. Examiners can administer the subtests from one or both of the DTLA-5 domains, depending on the purpose of the evaluation.
Evidence of the validity of DTLA-5 test scores is provided for content-description validity, criterion-prediction validity, and construct-identification validity. Content-description validity is demonstrated through careful documentation of subtest and item selection and analysis. A particularly powerful method for content-description validity is the use of conventional item analysis procedures, which allow the identification of good items and the deletion of bad items.
Criterion-prediction validity is explored by comparing the results of the DTLA-5 with those of other cognitive tests, such as the CAS2, PTONI, SB-5, UNIT2, WISC-IV, WISC-V, and WJ III. New and extensive criterion-prediction validity studies were conducted to demonstrate the validity of the DTLA-5’s subtests and composites, including diagnostic accuracy and receiver operating characteristic/area under the curve (ROC/AUC) analyses. Diagnostic accuracy analyses are particularly rigorous techniques for establishing validity involving the computation of a test’s sensitivity index, specificity index, and ROC/AUC. These studies indicated that the DTLA-5 is a highly valid measure of cognitive ability.
