To analyse the inter- and intra-examiner reliability of the VIDA questionnaire, and their concordance with the 鈥渢imed get up and go鈥?test in people aged 鈮?5 years.
Descriptive study of a diagnostic test.
Primary Health Care.
Application of 71 pairs of VIDA questionnaire, by one (38) or two professionals (33), in people aged 鈮?5 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.
Overall score of VIDA questionnaire, 鈥済et up and go鈥?test (functional), Pfeiffer questionnaire (cognitive), and risk factors of frailty (comorbidity, falls, recent hospitalisation, sensory disturbance, social impairment, polypharmacy).
Mean age 81.3 years 卤 4.8, with a 65.5%moderate-severe change in Barthel index. The mean score of the questionnaire was 31.3 卤 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 鈥済et up and go鈥?test (n 67) 0.61 (moderate), P < 0.0001. Lower score if there are 鈮?2 frailty factors (P = 0.015).
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.
