The most common pattern is that the older sibling becomes the abuser of the younger sibling, often against his or her will. In many cases, both parents were inaccessible. The fathers were deceased, or had abandoned their families after the birth of the child. The mothers were non-available because of drug addiction, alcoholism and/or mental illness. Further, families with non-divorced parents were characterized by parents engaged in extramarital affairs and exposing the children to a sexual climate. The absence of the father in chaotic families can lead to girls being abused by their brothers. In one study, 32 adolescent sibling offenders and 28 adolescent non-sibling offenders were compared (Royzman, Leeman, & Sabini, 2008)The sibling offender group reported significantly more marital discord (between parents), parental rejection, physical discipline, negative family atmosphere and general dissatisfaction with family relationships. Family factors related to sibling incest namely, parental rejection, abuse and marital conflicts.
Their conclusion is that family dynamics have a key role in creating the context where sibling
Incest could occur. Many sibling offenders have also grown up in families with many children; the average being three. Some studies point to neglect as an underlying dimension of sibling incest and that an older sibling is using a younger sibling to satisfy emotional needs, rather than a need for sexual gratification (Hargett, 2007). Parental rejection is also found to be more frequent in a sibling incest group than in a non-sibling group (Walsh & Krienert, 2011). A substantial proportion of parents of sibling incest offenders had themselves been victims of sexual and/or physical abuse; this could partly explain the dysfunction in many of these families (Busquet, Leveille, & Feron, 2009) and that a lack of parental involvement makes it possible to act out without being detected. Different kinds of abusive behaviors between siblings can also be described as a triadic affair, including the parents as reinforcing or seeing the abuse without hindering the children (Hargett, 2007).Some other demographics include the ages of sibling incest offenders ranging from 13 to 19 years, while victims’ ages range from 5 to 11 years old. Most abuse lasted an average of 22 months (Latzman, Viljoen, Scalora, & Ullman, 2010)
Simple or Complex Trauma
Sibling Incest is considered to be a complex trauma. Its complexity is in the duration of the abuse, the neglect of parental figures, the unwillingness to commit to secrecy, and the cultural stigma of family business remaining inside the home (Ballantine, 2011). For instance, the repetition in abuse over a lengthy period of time causes traumatic experiences and developmental disorders. The dysfunctions within these families have resulted from the physical and emotional absence of parents causing a prepositioned trauma and a built up tolerance for trauma experiences that follow.
