尽管母亲乳腺癌的影响对于许多孩子来说都是重大的，但目前没有有效或可靠的定量测量孩子对母亲疾病所持有的关切的方法，这限制了科学和临床实践。本研究旨在开发并对与母亲癌症相关的儿童报告的疾病相关关切的初始测量进行心理测量评估。该研究分为三个阶段：范围审查、从一项涉及孩子对于与母亲乳腺癌相关的一般问题的问题集合中提取问题、以及使用证实性因子分析测试这些提取的问题的三个提出的结构模型。范围审查得出五个疾病相关关切的类别：家庭生活模式改变、不确定性、对疾病传染的担忧、母亲死亡和母亲身体状况。为反映这五个类别，从202名学龄儿童完成的93项关于母亲乳腺癌的问卷中提取了18个问题。接下来，提出了三个结构模型来评估疾病相关关切的构念效度：五因子模型、三因子模型和一因子模型。使用证实性因子分析来测试和比较这些模型。五因子模型最符合数据，并且每个因子的内部一致性可靠性都足够。这些结果与通过范围审查得出的先验五因子模型一致。结果提供了18项儿童疾病相关关切量表的构念效度的初步证据，该量表可用于评估儿童的关切并指导未来的干预研究。版权所有©2023 Wolters Kluwer Health, Inc. 保留所有权利。

Despite the effect of maternal breast cancer on many children, there is no valid or reliable quantitative measure of the concern that children attribute to their mothers' disease, which constrains both science and clinical practice.This study aimed to develop and psychometrically evaluate the initial measures of child-reported, illness-related concerns associated with maternal cancer.The study was conducted in three phases: scoping review, item extraction from a battery of items obtained from school-aged children about general issues related to their mothers' breast cancer, and testing of the three proposed structural models of these extracted items using confirmatory factor analysis. The scoping review yielded five categories of illness-related concerns: altered family routines, uncertainty, concerns about illness contagion, maternal death, and maternal well-being. To reflect these five categories, 18 items were extracted from a 93-item questionnaire completed by 202 school-aged children regarding their mothers' breast cancer. Next, three structural models were hypothesized to assess the construct validity of illness-related concerns: five-, three-, and one-factor models. Confirmatory factor analysis was used to test and compare the models.The five-factor model best fit the data, and each factor showed adequate internal consistency reliability. These findings align with the a priori five-factor model informed by the scoping review.The results provide initial evidence of the construct validity of the 18-item Children's Illness-Related Concerns Scale, which can be used to assess children's concerns and inform future intervention studies.Copyright © 2023 Wolters Kluwer Health, Inc.
