由于全世界老年人的数量迅速增加，预计在未来几十年中，老年人中虚弱的流行程度将会加剧。关键是要认识到早发症状，以启动具体的预防护理。因此，需要使用适当的筛查工具及早发现脆弱性。这项研究的目的是评估格罗宁根脆弱指数(GFI)的潜在维度，这是一种广泛使用的自我报告筛查工具，用于识别虚弱的老年人。此外，对GFI分量表的效标效度进行了检验，并对GFI分数的构成进行了评估。采用横断面研究设计，评价GFI问卷在65岁及以上老年人中的结构效度、内部一致性和效标效度。所有受试者都完成了GFI问卷(n = 1508)。为了评估标准的有效性，119名老年人的小样本完成了额外的问卷：德容·吉尔维尔德孤独量表、医院焦虑抑郁量表、兰德-36身体功能和EuroQol-5D的感知一般健康项目。使用探索性因素分析和Mokken量表分析来评价GFI的结构效度。构建了一个维恩图来显示虚弱受试者的GFI分量表分数的构成。GFI的因素结构支持量表的三维结构。日常活动和心理社会功能分量表具有较好的内部一致性、可测性和效度效度(日常活动：克朗巴赫α = 为0.81，HS = 为0.84，r = −为0.62；心理社会功能为克朗巴赫α = 为0.80，HS = 为0.35，r = −为0.48)。健康问题子量表的内部一致性较差，但信度和效度可接受(克朗巴赫的α = 为0.57，HS为 = 为0.35，r为 = −为0.48)。目前的数据表明，90%的虚弱老年人在心理社会功能领域遇到了问题。目前的研究结果支持GFI的三维因素结构，表明使用GFI对脆弱性进行多维评估是可能的。与单一总和GFI评分相比，这些GFI子量表评分产生了更丰富的脆弱评估，并且它们的使用可能有助于为老年人提供更有针对性和个性化的护理。
Due to the rapidly increasing number of older people worldwide, the prevalence of frailty among older adults is expected to escalate in coming decades. It is crucial to recognize early onset symptoms to initiate specific preventive care. Therefore, early detection of frailty with appropriate screening instruments is needed. The aim of this study was to evaluate the underlying dimensionality of the Groningen Frailty Indicator (GFI), a widely used self-report screening instrument for identifying frail older adults. In addition, criterion validity of GFI subscales was examined and composition of GFI scores was evaluated. A cross-sectional study design was used to evaluate the structural validity, internal consistency and criterion validity of the GFI questionnaire in older adults aged 65 years and older. All subjects completed the GFI questionnaire (n = 1508). To assess criterion validity, a smaller sample of 119 older adults completed additional questionnaires: De Jong Gierveld Loneliness Scale, Hospital Anxiety Depression Scale, RAND-36 physical functioning, and perceived general health item of the EuroQol-5D. Exploratory factor analysis and Mokken scale analysis were used to evaluate the structural validity of the GFI. A Venn diagram was constructed to show the composition of GFI subscale scores for frail subjects. The factor structure of the GFI supported a three-dimensional structure of the scale. The subscales Daily Activities and Psychosocial Functioning showed good internal consistency, scalability, and criterion validity (Daily Activities: Cronbach’s α = 0.81, Hs = .84, r = −.62; Psychosocial Functioning: Cronbach’s α = 0.80, Hs = .35, r = −.48). The subscale Health Problems showed less strong internal consistency but acceptable scalability and criterion validity (Cronbach’s α = .57, Hs = .35, r = −.48). The present data suggest that 90% of the frail older adults experience problems in the Psychosocial Functioning domain. The present findings support a three-dimensional factor structure of the GFI, suggesting that a multidimensional assessment of frailty with the GFI is possible. These GFI subscale scores produce a richer assessment of frailty than with a single overall sum GFI score, and likely their use will contribute to more directed and customized care for older adults.
