Perceptions of MMPI item subtlety: influences of age and ethnicity

This study examined the influences of age and ethnicity on perceived item subtlety in Minnesota Multiphasic Personality Inventory (MMPI) Scales F and 9. One hundred twenty-one male adolescents (67 White, 54 Black) rated the items composing these scales in terms of their relationship to a psychological problem. The mean item ratings and subsequent subtle-obvious classifications were then compared to established ratings obtained from adults (Christian, Burkhart, & Gynther, 1978; Wiener, 1948). Results indicated significant differences in both item ratings and classifications between adolescents and adults on Scales F and 9. Significant differences between Black and White adolescents were found on Scale F but not on Scale 9, even when differences in verbal-comprehension abilities between groups were considered. These results suggest that it may be inappropriate to use current subtle-obvious keys with adolescents and minorities.
