Validity of electronically administered Recent Physical Activity Questionnaire (RPAQ) in ten European countries

Objective: To examine the validity of the Recent Physical Activity Questionnaire (RPAQ) which assesses physical activity (PA) in 4 domains (leisure, work, commuting, home) during past month. Methods: 580 men and 1343 women from 10 European countries attended 2 visits at which PA energy expenditure (PAEE), time at moderate-to-vigorous PA (MVPA) and sedentary time were measured using individually-calibrated combined heartrate and movement sensing. At the second visit, RPAQ was administered electronically. Validity was assessed using agreement analysis.
