Assessing physical activity
This systematic review includes 31 papers examining 30 different questionnaires assessing occupational physical activity. Evidence quality is generally low, with few questionnaires tested for both repeatability and validity. Four questionnaires are reliable in terms of repeatability, but none score highly on criterion validity (‘the extent to which scores on a particular instrument relate to a gold standard’).
