The Tilburg Frailty Indicator (TFI) is a 15-item scale. It diagnoses frailty in the elderly based on three domains: physical, psychological and social. A Spanish cross-cultural adaptation and its psychometric properties are presented here.
Independent, non-institutionalized ≥70 year-olds were recruited. The TFI structure was assessed with Kuder-Richardson (KR-20) and confirmatory factor analyses. Sperman´s correlations (r) with Timed Up-and-Go, Self-assessed-health, Fried criteria, Short Physical Performance Battery, Gerontopole Frailty tool, assessed convergent validity. Known groups' validity and test-retest reliability were tested.
Based on n = 856 participants, domain and total scale KR-20 were <0.70. The social domain and certain physical items did not fit adequately. Most physical and total scaler were 0.31-0.48. Social domain r were <0.30. The TFI differentiated frail and no-frail subjects, but test-retest variation was considerable.
TFI applicability at different social contexts and frailty stages are worth of additional study. Certain scale aspects should be reconsidered.
Tilburg 虚弱指数（TFI）是一个包含 15 个项目的量表。它基于身体、心理和社会三个领域来诊断老年人的虚弱程度。本文呈现了其西班牙语跨文化适应性及其心理测量学特性。
招募了独立的、非机构化的≥70 岁的老年人。使用 Kuder-Richardson（KR-20）和验证性因子分析评估 TFI 结构。Timed Up-and-Go、自我评估健康、Fried 标准、简短体能表现电池、Gerontopole 虚弱工具评估与收敛效度的斯皮尔曼相关系数（r）。测试了已知组的有效性和重测信度。
基于 n=856 名参与者，领域和总量表 KR-20<0.70。社会领域和某些身体项目的拟合效果不佳。大多数身体和总量表的 r 值在 0.31-0.48 之间。社会领域的 r 值<0.30。TFI 可以区分虚弱和非虚弱的受试者，但重测变异相当大。
TFI 在不同的社会背景和虚弱阶段的适用性值得进一步研究。某些量表方面需要重新考虑。
