The first group included 196 adolescents (age range 14-18) tested at a midwestern residential treatment facility for adolescents. The second group was the normative sample used in the standardization of the MMPI-A (Butcher, Williams, Graham, Archer, Tellegen, Ben-Porath, & Kaemmer, 1992. Minnesota Multiphasic Inventory-Adolescent (MMPI-A): manual for administration, scoring, and interpretation. Minneapolis: University of Minnesota Press.). The third group was the clinical sample: used in the validation of the MMPI-A (Williams & Butcher, 1989. An MMPI study of adolescents: I. Empirical validation of the study's scales. Personality assessment, 1, 251-259.). The MMPI-A data for each group of participants were run through a modified version of the MMPI-2 adaptive testing computer program (Roper, Ben-Porath & Butcher, 1995. Comparability and validity of computerized adaptive testing with the MMPI-2. Journal of Personality Assessment, 65, 358-371.). To determine the optimal amount of item savings, each group's MMPI-A item responses were used to simulate three different orderings of the items: (1) from least to most frequently endorsed in the keyed direction; (2) from least to most frequently endorsed in the keyed direction with the first 120 items rearranged into their booklet order; and (3) all items in booklet order. The mean number of items administered for each group was computed for both classification and full- scale elevations for T-score cut-off values of 60 and 65. Substantial item administration savings were achieved for all three groups, and the mean number of items saved ranged from 50 items (10.7% of the administered items) to 123 items (26.4% of the administered items), depending upon the T-score cut-off, classification method (i.e. classification only or full-scale elevation), and group.

A modification of the countdown method was tested to determine the usefulness, in terms of item administration savings, of several different test administration procedures. Substantial item administration savings were achieved for all four samples, though the clinical samples required administration of more items to achieve accurate classification and/or full-scale scores than did the personnel-selection samples. The use of normative item endorsement frequencies was found to be as effective as sample-specific frequencies for the determination of item administration order.
