Background Physical activity constitutes an important factor for the assessment of quality of life of people with heart failure. The Global Physical Activity Questionnaire has never been used for the evaluation of physical activity of people with heart failure. Aims The purpose of this study was to translate the Global Physical Activity Questionnaire into Greek and examine its reliability in 120 patients with heart failure. Methods The reliability of the tool was examined in a sub-population of the sample (30 patients with heart failure), 15 days after the first completion of the questionnaire. Findings Total score of physical activity was low (458.99 METs-minutes/week), whereas sedentary behaviour was very high (741.43 minutes/week). There was no decline between the first and second measurements, and the two measurements were statistically significantly correlated. Conclusions The findings provide evidence that the Greek version of the Global Physical Activity Questionnaire is a reliable tool for assessing the physical activity of Greek patients with heart failure.
