Link between Sleep Quality and Subsequent Pain Catastrophizing is Moderated by Time of Day. Sleep quality refers to within-subject changes in sleep quality. Poor sleep (solid line) is identified as one Standard Deviation below the average person centered mean. Good sleep (dashed line) is identified +1 SD refers to one Standard Deviation above the average person centered mean. Good sleep (dashed line) is associated lower pain catastrophizing in the morning hours, but this pain catastrophizing increases over the course of the day.
