Family presence during resuscitation (FPDR) is a growing health care practice; nevertheless, countless controversies surround this medical principle. Several studies have investigated the perceptions of health care professionals toward FPDR, yet psychometrically sound instruments assessing family members' perceptions of FPDR are scarce. Hence we aimed to develop and psychometrically validate the Family Presence During Resuscitation Benefits-Risks Scale (FPDR-BRS).
Using a methodological design, an initial 27-item questionnaire was developed after extensive literature and theoretical review. Psychometric validation assessed content validity through a 2-step process involving expert nurses and doctors, basic item analysis, internal consistency using Cronbach's α, and construct validity via exploratory factor analysis. After acquiring Ethics Review Board approval, the FPDR-BRS was tested on 130 randomly selected eligible family members from a tertiary government hospital in the Philippines.
The initial 27-item questionnaire was reduced to 23 items after content validation, yielding an item content validity index and scale content validity index/Ave rage of 1.00. Basic item analysis revealed acceptable inter-item and item-scale correlations. Exploratory factor analysis extracted 4 factors, namely, personnel risks, personal risks, insight-building benefits, and connection-forming benefits. Cronbach's α for the entire scale was 0.90, with high subscale reliability coefficients.
The 23-item FPDR-BRS exhibited satisfactory psychometric properties and may be used to quantitatively measure a family member's perception towards witnessing the resuscitation of his or her significant other. Further comprehensive psychometric evaluations are warranted to ensure robust cross-cultural comparisons.
复苏期间家属在场（FPDR）是一种日益普遍的医疗行为；然而，围绕这一医学原则存在无数争议。多项研究调查了医护人员对FPDR的看法，但评估家庭成员对FPDR看法的心理测量学上可靠的工具却很少。因此，我们旨在开发并在心理测量学上验证复苏期间家属在场利弊量表（FPDR - BRS）。
采用一种方法学设计，在广泛的文献和理论综述后，编制了一份初始包含27个条目的问卷。心理测量学验证通过两步过程评估内容效度，这两步过程涉及专家护士和医生、基本项目分析、使用克朗巴哈α系数的内部一致性以及通过探索性因素分析的结构效度。在获得伦理审查委员会批准后，FPDR - BRS在菲律宾一家三级政府医院随机选取的130名符合条件家庭成员中进行了测试。
经过内容验证后，初始的27个条目的问卷减少到23个条目，产生了一个条目内容效度指数和量表内容效度指数/平均值为1.00。基本项目分析显示项目间和项目 - 量表相关性可接受。探索性因素分析提取了4个因素，即人员风险、个人风险、洞察构建益处和关系形成益处。整个量表的克朗巴哈α系数为0.90，各子量表可靠性系数较高。
23个条目的FPDR - BRS表现出令人满意的心理测量学特性，可用于定量测量家庭成员对目睹其重要他人复苏的看法。有必要进行进一步全面的心理测量学评估，以确保进行有力的跨文化比较。
