Ambiguous loss_abstracts_2019-2023

The study encompassed abstracts of articles aligned with ambiguous loss published between 2019-2023, retrieved from PsycInfo, Web of Science (WoS), and Scopus. To eliminate the bias in the literature review, the study extracted published articles, dissertations, book chapters, and preprints with titles containing the search term “ambiguous loss”.Two reviewers (the first and the third authors worked independently) examined titles and abstracts and identified papers highlighting physical (n=34) or psychological (n=23) types of ambiguous loss. The study applies the conceptual and relational content analysis of Leximancer (version 4.5) to develop three cluster maps and lists of concepts separately for physical and psychological types and all selected papers published between 2019-2023. The results show that the physical type primarily encompasses situations related to foster adoption, potentially leading to the ambiguous loss experienced by both biological parents and children when facing forced separation. Psychological types include parents of children with disabilities, sudden infant and shaken baby syndromes, and caregivers of individuals with brain injuries and cancer. The present study indicates that the conceptual boundaries between physical and psychological types of ambiguous loss are not only expanding but also erasing, giving way to new applications in settings such as the COVID-19 pandemic, organ donor families, and sexual and gender minority.

本研究纳入2019-2023年间发表的与模糊丧失（ambiguous loss）相关的论文摘要，数据检索自PsycInfo、Web of Science（WoS）及Scopus三大数据库。为规避文献综述中的偏倚，本研究提取了标题包含检索词"模糊丧失（ambiguous loss）"的已发表论文、学位论文、图书章节及预印本文献。两名评审员（即第一作者与第三作者）独立审阅论文标题与摘要，筛选出聚焦于躯体性模糊丧失（n=34）与心理性模糊丧失（n=23）的文献。本研究采用Leximancer（版本4.5）的概念与关系内容分析法，分别针对躯体性模糊丧失、心理性模糊丧失及2019-2023年收录的全部入选文献，构建了三类聚类图谱与概念列表。结果显示，躯体性模糊丧失主要涉及寄养收养场景，可导致亲生父母与子女被迫分离时产生的模糊丧失体验；心理性模糊丧失则涵盖残疾儿童父母、婴儿猝死综合征与摇晃婴儿综合征患者家属，以及脑损伤与癌症患者的照料者群体。本研究表明，躯体性与心理性模糊丧失的概念边界不仅持续拓展，亦逐渐趋于消弭，现已在新型冠状病毒肺炎（COVID-19）大流行、器官捐献者家属及性与性别少数群体等场景中衍生出全新应用领域。
