Validity of the 16 PF and the MMPI in a mental hospital setting.

Administered the MMPI and 16 PF to 201 15-60 yr. old new admissions to a state mental hospital. Correlations between the 2 sets of scale scores were examined directly and by factor analysis. 3 common factors appeared to be represented to some extent in both instruments. The 16 PF appeared weak in the measurement of the more serious kinds of psychopathology, and had strongest loadings in a common factor identified with the validity scales of the MMPI. The 16 PF was found to measure 3 higher-order factors of personality not represented in the MMPI, but they do not appear highly relevant for assessment in a disturbed mental hospital population. Numerous significant relationships to psychiatrically relevant background variables were identified in analyses of profiles derived from both instruments.
