Concurrent validity and accuracy of the short-form of international physical activity questionnaire (SF-IPAQ) in a population of Spanish cancer survivors

Abstract

International organizations recommend cancer survivors to engage in 150 minutes of moderate physical activity per week. The American Heart Association established the importance of regularly evaluating physical activity (PA) levels. The evaluation tool can be subjective (questionnaire) or objective (accelerometer, podometer, etc). SF-IPAQ evaluates PA in last seven days and it is one of most used in the world. However the evidence for using SF-IPAQ as an indicator of PA could be weak. No questionnaires have been validated in the Spanish population of cancer survivors. The objective of this study is to compare PA and sedentary time from self-administered, short version of the IPAQ with data from accelerometer and with physical fitness data in a sample of Spanish cancer survivors.
