The Frail-VIG index and the Braden scale are validated instruments for assessing frailty and the risk of developing dependency-related skin lesions respectively. The Frail-VIG index is a multidimensional instrument that allows rapid and efficient assessment of the degree of frailty in the context of clinical practice.
Our aim was to investigate the convergent and discriminative validity of the Frail-VIG index with regard to Braden scale value.
We carried out a cross-sectional study in 2 primary health care centres of the Catalan Institute of Health, Barcelona (Spain). Participants in the study were all people included under a home care programme during the year 2018. No exclusion criteria were applied. We used the Frail-VIG index to measure frailty and the Braden scale to measure the risk of developing pressure ulcers. Trained nurses administered both instruments during face-to-face assessments in a participant's home during usual care. The relationships between both instruments were examined using Pearson's correlation coefficient.
Four hundred and twelve participants were included. Frail-VIG score and Braden scale value were negatively correlated (r=-0.597; P<.0001). Non-frail people had a lower risk of developing dependency-related skin lesions than moderate to severe frail people. The Braden scale value declined significantly as the Frail-VIG index score increased.
Frail-VIG index demonstrated a convergent validity with the Braden scale. Its discriminative validity was optimal, as their scores showed an excellent capacity to differentiate between people with a higher and lower risk of developing. These findings provide additional pieces of evidence for construct validity of the Frail-VIG index.
脆弱-活力指数（Frail-VIG index）和布拉德评分表（Braden scale）分别是用于评估虚弱程度和发生与依赖相关皮肤损伤风险的有效工具。脆弱-活力指数是一种多维度工具，可在临床实践中快速有效地评估虚弱程度。
我们的目的是研究脆弱-活力指数相对于布拉德评分表值的收敛效度和区分效度。
我们在西班牙巴塞罗那加泰罗尼亚卫生研究所的2个初级卫生保健中心进行了一项横断面研究。研究参与者为2018年期间纳入家庭护理计划的所有人。未应用排除标准。我们使用脆弱-活力指数来衡量虚弱程度，使用布拉德评分表来衡量发生压疮的风险。经过培训的护士在日常护理期间于参与者家中进行面对面评估时使用这两种工具。使用皮尔逊相关系数检查两种工具之间的关系。
纳入了412名参与者。脆弱-活力指数得分与布拉德评分表值呈负相关（r = -0.597；P <.0001）。非虚弱者发生与依赖相关皮肤损伤的风险低于中度至重度虚弱者。随着脆弱-活力指数得分增加，布拉德评分表值显著下降。
脆弱-活力指数与布拉德评分表具有收敛效度。其区分效度最佳，因为它们的得分显示出区分发生风险高低人群的出色能力。这些发现为脆弱-活力指数的结构效度提供了更多证据。
