MMPI traits of incestuous fathers

Compared MMPI scores of a group of 10 documented incestuous fathers and stepfathers to those of a matched control group of nonincestuous fathers. Analyses of variance and covariance reflected more pathological scores for incest fathers than control fathers on the psychopathic deviate scale, the psychasthenia scale and the schizophrenia scale of the MMPI. Results were discussed in terms of a character disordered personality type among incestuous fathers.
