Incest is both more common and more severe in stepparent families. The reasons for this have been unclear. In this comparison of 59 incestuous stepfathers, 70 incestuous biological fathers, and 158 offenders against unrelated children, there were few substantial differences in psychological characteristics between fathers and stepfathers, but their life histories and marital histories differed significantly. Stepfathers were significantly more likely to have prior convictions for sexual offenses, to have been sexually abused as a child, and to have juvenile criminal records. Stepfathers were more likely to have histories of previous marital failure. There was great heterogeneity of psychological characteristics. Increased prevalence in incest in stepfamilies is probably related to interactions between stepfathers' psychopathology, problems inherent in stepfamilies, and the availability of a potential victim.
乱伦在继父母家庭中更为常见且更为严重。其原因一直不明。在对59名有乱伦行为的继父、70名有乱伦行为的亲生父亲以及158名侵害非亲属儿童的罪犯进行的比较中，父亲和继父在心理特征上几乎没有实质性差异，但他们的生活经历和婚姻经历却有显著不同。继父有性犯罪前科、童年曾遭受性虐待以及有少年犯罪记录的可能性显著更高。继父更有可能有过以前婚姻失败的经历。心理特征存在很大的异质性。继父母家庭中乱伦现象增多可能与继父的精神病理学、继父母家庭固有的问题以及潜在受害者的可得性之间的相互作用有关。
