A cross‐sectional survey interview assessed the theory of planned behavior variables and medical and demographic information. Participants wore activPAL™ (PAL Technologies Ltd, Glasgow, United Kingdom) accelerometers recording time spent supine, sitting, standing, and stepping during 7 days encompassing palliative whole brain radiotherapy treatments.</p> </sec> <sec id="pon3641-sec-0003" sec-type="section"> <title>Results</title> <p>Thirty‐one patients were recruited. Correlates of median time spent supine or sitting in hours per day were instrumental attitude (i.e., perceived benefits) of physical activity (<italic>r</italic> = −0.42; <italic>p</italic> = 0.030) and affective attitude (i.e., perceived enjoyment) of physical activity (<italic>r</italic> = −0.43; <italic>p</italic> = 0.024). Moreover, participants who sat or were supine for greater than 20.7 h per day reported significantly lower instrumental attitude (<italic>M</italic> = 0.7; 95% CI = 0.0–1.4; <italic>p</italic> = 0.051) and affective attitude (<italic>M</italic> = 0.7; 95% CI = 0.0–1.4; <italic>p</italic> = 0.041).

This information could inform intervention studies to increase physical activity in advanced cancer patients with brain metastases. Copyright © 2014 John Wiley & Sons, Ltd.</p> </sec> </abstract>
