Adolescents, the MMPI, and the issue of K correction: a contemporary normative study.
Current adolescent norms for the MMPI are based on data obtained 25 to 45 years ago, from samples established in 1947 to 1957 and 1964 to 1965 (Marks & Briggs, 1967). Recently, MMPIs from 1,315 normal adolescent females and males, aged 13 through 17 years, were gathered from a three-state midwest area. There were significant differences between contemporary adolescent MMPI response patterns and those obtained from the earlier adolescent samples. This article presents new K-corrected normalized T-score conversion tables to encourage research that compares the relative efficacy of profiles calculated with and without K correction.
