[Reliability of the PRISCUS-PAQ. Questionnaire to assess physical activity of persons aged 70 years and older].
A questionnaire (Q) to measure physical activity (PA) of persons ≥70 years for epidemiological research is lacking. The aim was to develop the PRISCUS-PAQ and test the reliability in community-dwelling people (≥70 years). Validated PA questionnaires were translated and adapted to design the PRISCUS-PAQ. Its test-retest reliability for 91 randomly selected people (36% men) aged 70-98 (76±5) years ranged from 0.47 (walking) to 0.82 (riding a bicycle). The overall activity score was 0.59 as determined by the intraclass correlation coefficient (ICC). Recording of general activities, e.g., housework (ICC=0.59), was in general less reliable than athletic activities, e.g., gymnastics (ICC=0.76). The PRISCUS-PAQ, which is a short instrument with acceptable reliability to collect the physical activity of the elderly in a telephone interview, will be used to collect data in a large cohort of older people in the German research consortium PRISCUS.
