There is nothing in the rank-order of birth or in the presence or absence of siblings that clearly distinguishes the incest offenders vs. children, except that they had an extraordinarily large proportion of brothers, the ratio being 131.7 brothers per 100 sisters.
The incest offender vs. children is characterized by a poor relationship with his father at ages fourteen to seventeen; 43 per cent (the largest of any group) did not get along well with their fathers. However, another 39 per cent got along well, so that, all in all, these offenders had only one of the poorer paternal relationships.
Their maternal relationship was, compared with other groups, poor —only a few groups had a worse adjustment. One fifth of the incest offenders vs. children did not get along with their mothers; this was the fourth largest percentage. Sixty per cent got along well, but 60 per cent in this situation is a low figure, being third from the lowest. It is interesting to note that the most comparable group, the heterosexual offenders vs. children, had a distinctly better relationship with both parents.
As is obvious from the preceding percentages, the incest offenders vs. children got along better with their mothers than with their fathers. The number who preferred the mother is much greater than the number who got along equally well with both parents, which is also true of homosexual offenders, heterosexual aggressors, and exhibitionists. The incest offenders vs. children are the only group of heterosexual offenders who exhibit this maternal preference. The combination of incest with a young person and the youthful partiality for the mother suggests an Oedipal phenomenon that we are not equipped to analyze.
Some 59 per cent of the incest offenders vs. children came from broken homes, a relatively high percentage. While most of the breakups occurred when the subject was under age ten, a substantial number (one fifth) occurred at a later age. However, the home of the average (median) boy broke up when he was 7.2 years old—an age earning him a central location in that rank-order.
The incest offenders vs. children experienced more interparental friction than any other group. They not only reported the highest percentage (39 per cent) of parents who got along with one another badly, but the lowest percentage (36 per cent) who got along well. The family situation, in toto, seems to have been relatively miserable: poor adjustment to both parents who, in turn, did not get along well with one another. Of course, in over one half of the cases this unhappy situation was during a second marriage; we lack data on the family relationship during the first marriage, but it cannot have been a happy one since it was usually terminated by separation or divorce. To add to the marital problems, these families were financially worse off than the families of other groups; nearly half reported their parental economic status as poor or very poor.
As a partial consequence of the large percentage of individuals whose parental homes broke up, we find that relatively few incest offenders vs. children lived 15 or more years in a home with a husband and wife present. This is not wholly the product of a high divorce figure—some other groups with even greater percentages of broken homes exceed the incest offenders vs. children in the number of years spent with a husband and wife. It would seem that, possibly because there had been so much friction between them, the parents were loath to remarry soon, and waited longer than the parents of other types of sex offenders. In addition, after the original home broke up these children were transplanted more frequently than most, the average number of new living arrangements being nearly two.
We saw that the heterosexual aggressors vs. children, who also had unhappy home lives, seem to have turned in a compensatory way to children of their own ages. The same is true of the incest offenders vs.
children. At ages ten to eleven they had quite good socialization with their peers, especially with girls. In terms of percentage they had more girl companions than any group save the homosexual offenders. This social good fortune seems more typical of sex offenders against children than of sex offenders against older females, which is significant.
The ability to get along well with females is reflected, in the case of incest offenders vs. children, in their prepubescent sex play: in this they were next to the most active of any group (84 per cent). This play was primarily heterosexual, some 75 per cent having had heterosexual play (the second highest percentage of any group). Moreover, more of the incest offenders vs. children than any other class of offenders or control confined their activity to girls (36 per cent).
This emphasis on heterosexual behavior did not, however, result in any particular elaboration of sexual techniques. Insofar as mouth-genital contact and coitus are concerned the incest offenders vs. children do not stand out among other sex offenders, but all were more sophisticated in this respect than the members of the control group.
While primarily heterosexual, a fair percentage (48 per cent) had had homosexual experience before puberty, but very few had been exclusively homosexual. Their homosexual play was ordinarily confined to a single year, and their techniques were, in percentage terms, not unusual. In fact, fewer of the incest offenders vs. children indulged in mutual masturbation and anal coitus than did the control-group individuals.
One might expect that the future incest offenders vs. children would have experienced heterosexual activity with adults, especially relatives, but in fact they are average in this respect. In terms of physical contact with adult males, they are well below average—being third from last in rank-order. It is significant that in homosexual contact with adult males the incest offenders rank next to last, third from last, and fourth from last (the control group being last). While the percentages are very small, an equal number of incest offenders vs. children had sexual contact with adult females and with adult males.
The childhood health of the incest offender vs. children was in no way unusual; in fact, in an over-all rating the early health of this group was essentially the same as that for the control group.
A large percentage—over half—of the incest offenders vs. children masturbated before reaching puberty. This trait, coupled with their high incidence of prepubertal sex play, makes them one of the sexually most active groups of all in preadolescence. Their hypersexuality is in striking contrast to the other incest offenders, and can be explained only in part by their earlier pubescence (prepubertal sex play is correlated with early puberty).
