Marital relations in incest offenders

The study compared 92 incest perpetrators to 40 (noncriminal) married males on two marital inventories, the Clarke Martial Relations Questionnaire (CMRQ), and the Sexual Behavior and Marital Satisfaction Questionnaire (SBMSQ). Results showed that marital disharmony, in the form of mistrustfullness, lack of mutual friends and time together, emotional instability (in both partners), but not sexual relations, were predominant factors in incest perpetrators' profiles. A discriminant function analysis correctly classified 91.3% of incest offenders, but only 30.0% of controls, into their a priori group. Incest perpetrators reported less mutual give-and-take in disagreements with their spouses, a trend to confide less in their wives, and being more lonely in their marriage. Incest offenders reported they knew their spouses less well prior to marriage, despite the lack of any between-group differences in length of marriage or number of prior marriages. No differences emerged with respect to the range of sexual behaviors experienced or the degree of satisfaction with them. There were no group differences in the frequency of coitus nor in sexual dysfunction. In general, the lack of a satisfying emotional relationship between the incest offenders and their wives appeared as the most prominent factor in their marital relationships. The prominent aspects of their marital disharmony and sexual relations identified in the study reflect, in part, the inherent treatment goals needed for the incest perpetrator.
