An exploration of the quality and dynamics of sibling relationships, in the context of sibling sexual abuse.

据估计，兄弟姐妹性虐待（SSA）是父母对儿童性虐待的三倍（耶茨和阿勒代斯，2021）。到目前为止，还没有一个普遍认可的标准来区分无害的兄弟姐妹性行为和SSA，但人们一致认为SSA通常包括不适合年龄的行为，性质严重，并且不是出于与年龄相适应的好奇心（耶茨和阿勒代斯，2021）。尽管模棱两可，但研究表明，SSA与广泛的不良结局相关，这些结局在成年期表现出实质性的连续性（Caffaro，2020）。兄弟姐妹关系是我们拥有的最重要的关系之一（邓恩，2007）。这种关系可以显着影响个人发展，是独特的，因为它们的特点是爱，和友谊，但也嫉妒和竞争（桑德斯，2004）。兄弟姐妹通常被视为平等的，关系中的权力差异经常被忽视（Punch，2008）。然而，兄弟姐妹二人组的一个共同特征是权力动态的相互作用，这可能受到年龄，出生顺序，性别和文化的影响（Dunn，2007）。尽管兄弟姐妹关系的重要性和复杂性得到了公认，但对性虐待兄弟姐妹关系的性质和动态的研究仍存在不足。该博士将通过探索童年SSA对成年受害者-幸存者的影响以及SSA如何影响整个生命周期兄弟姐妹关系的质量和动态，对知识做出原创性贡献。尽管有证据表明SSA具有终身影响（Caffaro，2020），但很少有人关注SSA对兄弟姐妹关系的影响。现有的小证据基础表明，性虐待的兄弟姐妹关系往往具有更广泛的家庭功能障碍，性别角色和父母缺席/偏袒的复杂性（耶茨和阿勒代斯，2021）。此外，关于性虐待兄弟姐妹关系的大部分知识，在整个生命周期中，仅基于犹太-以色列参与者（Tener，2019）。然而，众所周知，文化差异影响和塑造兄弟姐妹关系，特别是在虐待的背景下（Marmor & Tener，2022）。本博士将通过探索英国，SSA成年受害者幸存者的叙述来扩大对性虐待兄弟姐妹关系的理解。本博士有两个主要目标：首先，探索成年受害者幸存者如何构建他们的SSA经历;其次，研究受害者幸存者如何在整个生命周期中理解他们的兄弟姐妹关系。本研究将采用质性研究范式和叙事研究方法。半结构化访谈将被用来收集回顾性叙述从SSA成年受害者幸存者，关于他们如何使他们的兄弟姐妹关系的意义在整个生命周期。为了分析数据，将使用叙述性专题分析（Riessman，2008年）。本研究的目的是产生新的知识，这将提供家庭，专业人士和决策者与性虐待的兄弟姐妹关系的多层面性质的更多的循证理解。这反过来将有助于帮助更好的专业决策，并将提供更明确的指导，如何治疗支持儿童和成年SSA受害者幸存者。此外，这项研究将提供更清晰的兄弟姐妹团聚后披露和恢复性司法的兄弟姐妹受SSA的影响，同时提供有意义的贡献，现有的兄弟姐妹理论。

Sibling sexual abuse (SSA) is estimated to be three times as common as child sexual abuse committed by parents (Yates and Allardyce, 2021). To date there is no universally agreed criteria differentiating harmless sibling sexual behaviour and SSA, but there is consensus that SSA typically includes behaviours which are not age appropriate, are severe in nature, and are not motivated by age-appropriate curiosity (Yates and Allardyce, 2021). In spite of the equivocality, research suggests SSA is associated with a wide range of adverse outcomes which show substantial continuities into adulthood (Caffaro, 2020). Sibling relations are one of the most important relationships we have (Dunn, 2007). Such relationships can significantly impact on personal development and are unique in the sense that they are characterised by love, and friendship, but also jealousy and rivalry (Sanders, 2004). Often siblings are seen as equals, and power differentials within the relationship is frequently overlooked (Punch, 2008). However, a common feature of sibling dyads is the interplay of power dynamics, which may be influenced by age, birth order, sex and culture (Dunn, 2007). In spite of the recognised importance and complexity of sibling relations there is a deficit of research understanding the qualities and dynamics of sexually abusive sibling relationships. This PhD will make an original contribution to knowledge, through exploring what impact childhood SSA has on adult victim-survivors, and how SSA affects the quality and dynamics of sibling relations across the lifespan. Despite the evidence that SSA has lifelong implications (Caffaro, 2020), there is little attention regarding what impact SSA has on sibling relationships. The small existing evidence base suggests that sexually abusive sibling relations often have the added complexity of wider family dysfunction, gender roles, and parental absence/favouritism (Yates & Allardyce, 2021). Further, much of what is known about sexually abusive sibling relations, across the life-span is based on Jewish-Israeli participants only (Tener, 2019). However, it is well established that cultural differences influence and shape sibling relationships, particularly in the context of abuse (Marmor & Tener, 2022). This PhD will expand understandings of sexually abusive sibling relationships by exploring the narratives of UK, SSA adult victim-survivors.This PhD has two main aims: firstly, to explore how adult victim-survivors construct their experiences of SSA ; and secondly to examine how victim-survivors make sense of their sibling relationships across the lifespan. A qualitative paradigm and a method of narrative inquiry will be adopted. Semi-structured interviews will be used to gather retrospective narratives from SSA adult victim-survivors, about how they make sense of their sibling relationships across the life-span. To analyse the data narrative thematic analysis will be used (Riessman, 2008). The objective of this research is to generate new knowledge which will provide families, professionals, and policymakers with a more evidence-based understanding of the multidimensional nature of sexually abusive sibling relationships. This in turn will be useful in aiding better professional decision making and will offer clearer guidance on how to therapeutically support child and adult SSA victim-survivors. Further, this research will provide greater clarity on sibling reunification following disclosure and restorative justice for siblings affected by SSA; alongside providing meaningful contributions to existing sibling theory.
