[Inheritability of personality traits measured by MMPI in families of schizophrenic patients].

The results of genetic and mathematical analysis of MMPI-measured personality traits performed on material obtained 37 families of schizophrenia-afflicted probands were outlined. The results obtained suggest that heritability of traits in schizophrenic families is higher than in the general population. The discriminant function significantly differentiating between schizophrenics' and healthy people's relatives and having high heritability was calculated.
