Seven-Day Physical Activity Recall (PAR)


Originally developed for use in the Stanford Five-City Project in the early 1980s, the PAR is a semi-structured interview that estimates an individual's time spent in physical activity, strength, and flexibility activities for the 7 days prior to the interview. The general interview format is as follows: An interviewer asks the participant to recall time spent sleeping and doing physical activities for the past 7 days. The interviewer guides the participant through the recall process, day-by-day, to determine duration and intensity of the physical activities.

The purpose of this manual is to standardize the interview process and to increase agreement among interviewers. A standardized interview helps to decrease error by maintaining consistency across interviewers and limiting an interviewer's bias.
