Abstract

This study provides evidence of construct validity for the Brazilian version of the Godin-Shephard Leisure-Time Physical Activity Questionnaire (GSLTPAQ), a 1-item instrument used among 236 participants referred for cardiopulmonary exercise testing. The Baecke Habitual Physical Activity Questionnaire (Baecke-HPA) was used to evaluate convergent and divergent validity. The self-reported measure of walking (QCAF) evaluated the convergent validity. Cardiorespiratory fitness assessed convergent validity by the Veterans Specific Activity Questionnaire (VSAQ), peak measured (VO2peak) and maximum predicted (VO2pred) oxygen uptake. Partial adjusted correlation coefficients between the GSLTPAQ, Baecke-HPA, QCAF, VO2pred and VSAQ provided evidence for convergent validity; while divergent validity was supported by the absence of correlations between the GSLTPAQ and the Occupational Physical Activity domain (Baecke-HPA). The GSLTPAQ presents level 3 of evidence of construct validity and may be useful to assess leisure-time physical activity among patients with cardiovascular disease and healthy individuals.

Highlights

It is widely recognized that regular participation in physical activity and exercise results in several positive health-related outcomes, from both a preventive and a rehabilitative perspective 1. physical activity is defined as “any bodily movement produced by skeletal muscles that results in energy expenditure” 2 (p. 126). physical activity can further be categorized in a range of ways and the simplest classification identifies the physical activity that occurs during the different moments of a regular day: sleeping, at work, and at leisure 2.Nowadays it is acknowledged that there is less physical activity in the working environment in industrialized countries, due to an increase in technology and the automation of tasks, leading to people taking up more sedentary jobs 3

Summary

Introduction

Nowadays it is acknowledged that there is less physical activity in the working environment in industrialized countries, due to an increase in technology and the automation of tasks, leading to people taking up more sedentary jobs 3. For this reason, occupational physical activity has decreased over time 4 and leisure-time physical activity has received widespread attention, making it a more representative measure of physical activity practiced by the economically active population 5. The questionnaire has been used among different populations in several countries 8,9,10,11,12,13,14,15 and evaluated by different studies 16,17,18 and reviews 19,20
