Date of Award




Degree Name

Doctor of Philosophy (Ph.D.)




Prior research literature which has addressed the subject of sex offenders has proposed, in general, that child molesters tend to be passive, shy, and withdrawn, while rapists are more active, independent, and outgoing. There has been no effort to organize prior findings within a theory of personality. In the present study, Millon's (1969) theory of personality was used to make predictions about differential scoring patterns for child molesters and rapists on the Millon Clinical Multiaxial Inventory (MCMI). In addition, an attempt was made to replicate three prior studies using the MMPI. As predicted, rapists were found to score higher than child molesters on the Active dimension of the scale. The Ambivalent dimension was found to discriminate between the two groups, in that child molesters scored higher on the Passive Ambivalent scale and rapists scored higher on the Active Ambivalent scale. Other predictions were not supported. Data suggested that both groups showed changes which might be associated with length of hospitalization. The prior studies using the MMPI were not replicated.
