Parent and child MMPI responses: characteristics among families with adolescents in inpatient and outpatient settings.

The relationship of parent personality to child psychopathology has been investigated in numerous MMPI studies over the past three decades. Very few of these studies, however, have directly analyzed MMPI response patterns of both parents and offspring. The current study included the MMPI responses of 199 families with adolescents entering inpatient and outpatient psychiatric setting (N = 542). Inpatient parents and adolescents had significantly higher mean scores across a variety of MMPI scales than did their outpatient counterparts. The linear combination of adolescent and maternal MMPI scale data, in a stepwise discriminative function analysis, resulted in accurate classification of 75% of all children in inpatient treatment and 74% of all children assigned to outpatient treatment. Findings were discussed in terms of salient MMPI differences between inpatient and outpatient families and shared psychopathological characteristics among family members with offspring in psychiatric treatment settings.
