The Functional Status Score for the Intensive Care Unit (FSS-ICU) evaluates the physical function of ICU patients. The objective of the study was to translate and cross-culturally adapt the FSS-ICU into Korean and assess its reliability and validity.
An expert committee supervised the forward and backward translation process and the final translated version. Experienced physiotherapists assessed patients (= 31) from a medical ICU using the Korean version of FSS-ICU. Intra-class correlation coefficients (ICCs) and Bland-Altman's plots were used to evaluate reliability, and Cronbach's alpha for internal consistency. Construct validity was evaluated using Spearman's correlation coefficients.
Two physiotherapists in each of the two university hospitals independently assessed 31 medical ICU patients, with a mean FSS-ICU total score of 23 (range: 4-35). The FSS-ICU Korean version demonstrated excellent internal consistency, with Cronbach's alpha of 0.897 for the total FSS-ICU score, and a range of 0.844-0.892 with deletion of each individual activity within the FSS-ICU. Intra-rater and inter-rater reliability were excellent for all of five FSS-ICU activities and the total score, with an ICC range of 0.930-0.993. Bland-Altman's plots revealed a mean difference in FSS-ICU total score of 0.2 (95% limits of agreement: -1.9 to 2.3) between two physiotherapists. The Korean version of FSS-ICU had good convergent and divergent validity with moderate to strong correlation with mobility and muscle strength measures, and poor correlation with unrelated measures.
The Korean version of the FSS-ICU showed excellent intra-rater and inter-rater reliability, internal consistency, and construct validity for medical ICU patients. The results of this study, along with prior publications, support that the FSS-ICU Korean version is a valid and reliable assessment tool for the ICU environment.Implications for rehabilitationIntensive care unit patients usually experience decreased muscle strength and physical function.The Korean version of the Functional Status Score for the Intensive Care Unit (FSS-ICU) is suitable for use with Korean speakers and has a valid, reliable measurement tool for physical function of intensive care unit patients.A well-standardized training with videos and written materials is important to ensure correct implementation of the Korean version of the FSS-ICU.
重症监护病房功能状态评分（FSS-ICU）用于评估 ICU 患者的身体功能。本研究的目的是将 FSS-ICU 翻译并跨文化适应为韩语，并评估其可靠性和有效性。
一个专家委员会监督了正向和反向翻译过程以及最终的翻译版本。经验丰富的物理治疗师使用 FSS-ICU 的韩文版评估了来自医疗 ICU 的患者（=31 名）。使用组内相关系数（ICC）和 Bland-Altman 图评估可靠性，使用 Cronbach's alpha 评估内部一致性。使用 Spearman 相关系数评估结构效度。
两所大学医院的每个科室各有两名物理治疗师独立评估了 31 名医疗 ICU 患者，FSS-ICU 总分平均为 23 分（范围：4-35）。FSS-ICU 韩文版具有极好的内部一致性，FSS-ICU 总分的 Cronbach's alpha 为 0.897，删除 FSS-ICU 中的每项活动后范围为 0.844-0.892。所有五项 FSS-ICU 活动和总分的内部评分者间和评分者内可靠性均极好，ICC 范围为 0.930-0.993。Bland-Altman 图显示，两名物理治疗师之间 FSS-ICU 总分的平均差异为 0.2（95%置信区间：-1.9 至 2.3）。FSS-ICU 韩文版与移动性和肌肉力量测量值具有良好的收敛和发散效度，与不相关的测量值相关性差。
FSS-ICU 韩文版对医疗 ICU 患者具有极好的内部评分者间和评分者内可靠性、内部一致性和结构效度。本研究的结果与先前的出版物一起支持 FSS-ICU 韩文版是 ICU 环境中一种有效和可靠的评估工具。
重症监护病房的患者通常会出现肌肉力量和身体功能下降。
韩文版重症监护病房功能状态评分（FSS-ICU）适用于韩语使用者，是一种针对重症监护病房患者身体功能的有效、可靠的测量工具。
使用视频和书面材料进行标准化培训非常重要，以确保正确实施 FSS-ICU 韩文版。
