Sibling Sexual Abuse: A Review of Empirical Studies in the Field

Although sibling sexual abuse (SSA) is one of the most common forms of sexual abuse, it has been particularly neglected in previous research. Hence, characteristics of this form of abuse and its longer term implications are not well understood. The aims of the current review were to precisely characterize the phenomenon of SSA and to condense the implications known to date of SSA on survivors. We included 15 studies with a total sample size of 14,680 individuals. Our results indicate that SSA has some unequivocal features such as an early onset, an extended duration and frequency, and a particularly high intensity (i.e., involvement of coercion, force, superiority, and manipulation). Our findings also revealed that SSA is linked to later depression, anxiety, impaired self-esteem, and sexual functioning. The findings of the current review suggest that (1) SSA is common, (2) SSA has various negative effects on survivors’ mental health, and that (3) SSA and its implications have been and to date are marginalized in research and practice. Results are discussed with a special focus on clinical implications.

“And I Let It All Out”: Survivors’ Sibling Sexual Abuse Disclosures

There is consensus in child sexual abuse (CSA) literature with respect to the central role of the disclosure process. However, CSA disclosure is challenging for all children, those who have experienced intrafamilial abuse. In recent years, there has been growing research into sibling sexual abuse (SSA), which is a prevalent and severe, but also the least studied form of intrafamilial CSA. This study was designed to advance theory on SSA disclosure by examining the narratives of adults who have disclosed the abuse and discuss it with reference to the perceived role of disclosure recipients—including perpetrating siblings, parents, and professionals. In-depth interviews with 25 adults were conducted and analyzed thematically. The results highlighted the significance of disclosure for survivors, as well as the central roles played by significant others in the process, including the offending and nonoffending siblings, parents, and professionals. The discussion addresses the important role of the family system in the disclosure narratives. The conclusions point to the need of all actors taking part in the disclosure itself, as well as in the survivors’ lives postdisclosure, to become “better” disclosure recipients by acknowledging survivors’ needs. This in turn would also empower survivors to disclose their stories and cope with the potential familial and societal ramifications of their disclosure.
