(325) Does Time Variation between Study Visits Relate to Differences in Pain Ratings

Experimental pain research often requires research participants to complete multiple study visits. Variability in the  time difference between study visits may be a factor that should be controlled for in pain research. We aim to investigate the question of how variation in the time interval between two study visits affects pain ratings and whether anxiety or pain catastrophizing moderate this effect. During the first visit (V1), participants rated pain intensity (visual analog scale) after each noxious heat stimulus in a series (7 stimuli of 48°C, 10 seconds each).
