Abstract OBJECTIVE: To analyse the inter- and intra-examiner reliability of the VIDA questionnaire, and their concordance with the "timed get up and go" test in people aged ≥75 years. DESIGN: Descriptive study of a diagnostic test. LOCATION: Primary Health Care. SUBJECTS-INTERVENTION: Application of 71 pairs of VIDA questionnaire, by one (38) or two professionals (33), in people aged ≥75 years with no significant sensory or physical-psychic impairment. Stratified sample based on ADL (Barthel index) to obtain a variety of responses that would ensure a range of scores of the questionnaire. MAIN MEASUREMENTS: Overall score of VIDA questionnaire, "get up and go" test (functional), Pfeiffer questionnaire (cognitive), and risk factors of frailty (comorbidity, falls, recent hospitalisation, sensory disturbance, social impairment, polypharmacy). RESULTS: Mean age 81.3 years±4.8, with a 65.5\% moderate-severe change in Barthel index. The mean score of the questionnaire was 31.3±7.9, with a rank of 11 to 38 (maximum). There were no differences according to gender (P=0.78). Inter-examiner reliability (n 33): Intraclass Correlation Coefficient (ICC) 0.94, 95\% Confidence Interval (CI) 0.88-0.97, P<0.0001. Intra-examiner reliability (n 38): ICC 0.96, CI 0.93-0.98, P<0.0001. Correlation coefficient (rho of Spearman) with the "get up and go" test (n 67) 0.61 (moderate), P<0.0001. Lower score if there are ≥ 2 frailty factors (P=0.015). CONCLUSIONS: VIDA questionnaire is a very reliable tool, with no gender bias. It demonstrates an association with other functionality measures and with frailty factors in the elderly. Copyright © 2010 Elsevier España, S.L. All rights reserved.
