Purpose in life is associated with physical activity measured by accelerometer.

Previous research has shown that purpose in life, the belief that one's life is meaningful and goal-directed, is associated with greater engagement in self-reported physical activity. The purpose of this study was to examine the relationship between purpose in life and accelerometer-measured physical activity. Community volunteers (N = 104) completed measures of purpose in life and potential confounds and wore accelerometers for three consecutive days. Purpose in life was positively associated with objectively measured movement, moderate to vigorous physical activity, and with self-reported activity. These relationships were largely unchanged after controlling for potential confounds. These results suggest that purpose in life is a reliable correlate of physical activity.
