Abstract

BACKGROUND: Sibling sexual abuse is a common form of intra-familial sexual abuse, yet it remains under-studied and under-recognised, leaving many children unprotected and unsupported. Practitioners need rigorously conducted evidence syntheses to inform decision making in this complex practice area. OBJECTIVE: A scoping review was conducted with the broad research question: What is known about sibling sexual abuse? in order to map the research and to establish areas of knowledge and gaps requiring attention. METHOD: The review followed the guidelines of Arksey and O'Malley (2005), and through searches of 11 academic databases, 3 grey literature databases, journal handsearch and Google, identified 91 empirical papers for review. RESULTS: While poorly and inconsistently defined, sibling sexual abuse is a common form of child sexual abuse with significant consequences for the whole family. It may involve children of any age and sex, entail the full range of sexual behaviours, and can take place in families from across the socioeconomic spectrum. Disclosure is uncommon during childhood, with multiple barriers including the nature of the caregiving environment in which sibling sexual abuse often takes place. Official records are likely to under-report the frequency and duration of the abuse. CONCLUSIONS: There is considerable scope for further research across all aspects of sibling sexual abuse. This paper represents the most comprehensive (albeit not complete) overview of the current body of knowledge in this field to date, and presents key findings as well as a summary of practice and research recommendations.
