Peer Reviewed: Concurrent Validity of a Self-Reported Physical Activity Vital Sign Questionnaire With Adult Primary Care Patients

摘要

IntroductionNo tool currently used by primary health care providers to assess physical activity has been evaluated for its ability to determine whether or not patients achieve recommended levels of activity. The purpose of this study was to assess concurrent validity of physical activity self-reported to the brief (<30 sec) Physical Activity “Vital Sign” questionnaire (PAVS) compared with responses to the lengthier (3–5 min), validated Modifiable Activity Questionnaire (MAQ).
