Comparison of Automated and Standard Administration of the Purdue Pegboard with Mentally Retarded Adults

Standard and automated administrations of the Purdue Pegboard to 32 mentally retarded adults were compared in a test-retest paradigm. The automated administration involved videotape and audio input. Both types of administration yielded equivalent scores except on the assembly portion of the test where the difference favored the automated presentation. Spearman rank-order test-retest correlations over a 2-mo. period showed both types of test administration to be equally reliable.
