Evolutionary psychologists have suggested that stepchildren should be over-represented as victims of lethal parental violence compared with children living with their two genetic parents, because of relatively more lapses in parental solicitude among stepparents. In our study, using data over a period of 35 years in Sweden (1965-1999), there was no overall over-representation of stepchildren as victims. For very young stepchildren there was a tendency for over-representation. In families with both stepchildren and children genetically related to the offender, genetic children tended to be more likely to be victims.
进化心理学家认为，与与亲生父母双方共同生活的孩子相比，继子女作为致命性父母暴力受害者的比例应该过高，因为继父母在照顾孩子方面相对更容易出现疏忽。在我们的研究中，利用瑞典35年（1965 - 1999年）的数据，继子女作为受害者并没有总体上的比例过高情况。对于非常年幼的继子女，存在比例过高的趋势。在既有继子女又有与犯罪者有血缘关系的孩子的家庭中，亲生孩子往往更有可能成为受害者。
