Key Points

This research aims to evaluate the validity of the Global Physical Activity Questionnaire (GPAQ) in measuring moderate-vigorous physical activity (MVPA) and sedentary behavior (SB).
Levels of agreement with objective measurements were assessed to determine GPAQ validity.
Comparison of GPAQ's efficacy in measuring MVPA versus sedentary behavior.
The study involves intervention effectiveness analysis for promoting MVPA.
GPAQ shows high agreement with objective measures for moderate-vigorous physical activity.
Less validity was found in measuring levels and change in sedentary behavior.

Abstract

Levels of agreement with objective measurements indicate the GPAQ is a valid measure of MVPA and change in MVPA but is a less valid measure of current levels and change in SB. Thus, GPAQ appears to be an appropriate measure for assessing the effectiveness of interventions to promote MVPA.
