Used a programmable Hewlett-Packard scientific calculator (HP-67, 97, 41C, 41CV) to rapidly convert raw scores from adolescent MMPI protocols to T scores, scale by scale. The K factor is handled, as needed, automatically. The program is stored on one side of a standard HP magnetic card. The norm data for adolescents (or optionally any other group) in the age groups less than 15, 15, 16, and 17 occupy two sides per sex per age group of eight magnetic data cards. Complete scoring and profiling of the R-form MMPI can be done in less than 10 minutes.
