兒童性侵害的發生，源於施虐者以權カ破壞人際界限中最基本的信任感和安全感。受害當事人如何在成長歴程中建立和維持人際親密，無疑為發展過程必須面臨的重大挑戰。因此，此研究主要目的在於探討成年女性知覺兒時性侵害對人際界限之衝撃及其因應。以生命史做為研究方法，提出ニ個主要研究問題：對兒時性侵害經驗之知覺？成長歴程中，兒時性侵害經驗如何影響其人際界限？採用立意取樣方式，邀請五位受訪者進行深度訪談，所有訪談過程皆予以錄音，並依其口述資料，進行編碼，最後形成人我界限之侵犯和界限破壞之影響ニ個類屬。人我界限之侵犯，反映了至親至害、欠缺抵抗能力、施虐者發洩性慾三個主題；界限破壞之影響，呈現在人的自主性喪失、内在情緒衝突、人我界限之混淆三項主題。顯示兒時性創傷對其人際界限影響深遠，經檢視相關實證研究，進行深人綜合討論，並對於未來實務工作及研究方向，提供具體之建議。

Experiences of childhood sexual abuse (CSA) may compromise the survivor’s capacities for trust and safety in relationships. The purpose of this qualitative study is to examine the impact of CSA on interpersonal boundaries. A life-history approach was used to collect narrative data from five Taiwanese women with a history of CSA. In-depth interviews with the participants were audiotaped and transcribed. A line-by-line approach was used to develop themes. Two major theme categories, boundary violation and impact of violation, emerged from the analysis. The category of boundary violation reflects themes that CSA was perpetrated by trusted people, the lack of capacity to resist, and the sexual desires of the perpetrator. The category of impact of violation included themes of loss of autonomy, being filled with inner conflicts, and confusion of boundaries. Limitations of the current study, implications of the findings, and recommendations for future research are discussed.
