Development and validation of an intrinsic capacity composite score in the Longitudinal Aging Study Amsterdam: a formative approach
Abstract Background Intrinsic capacity (IC) defined by the WHO refers to the composite of five domains of capacities. So far, developing and validating a standardized overall score of the concept have been challenging partly because its conceptual framework has been unclear. We consider that a person’s IC is determined by its domain-specific indicators suggesting a formative measurement model. Aims To develop an IC score applying a formative approach and assess its validity. Methods The study sample (n = 1908) consisted of 57–88-year-old participants from the Longitudinal Aging Study Amsterdam (LASA). We used logistic regression models to select the indicators to the IC score with 6-year fu…
A New Functional Classification Based on Frailty and Disability Stratifies the Risk for Mortality Among Older Adults: The FRADEA Study.
Abstract Objectives The aim of the current study was to investigate whether a new functional classification, based on basic (BADL) and instrumental (IADL) activities of daily living and frailty, is associated with mortality in older adults during 10 years of follow-up. Design Cohort study, with a follow-up of 10 years. Setting and participants A total of 924 participants aged 70 and older from the Frailty and Dependence in Albacete (FRADEA) study, a population-based sample of Spanish older adults. Measures At baseline, a new functional classification of 8 categories was constructed with limitations in BADL using the Barthel Index, limitations in IADL using the Lawton IADL Index, and the cri…
