Abstract

In chronic pain, mental defeat is considered as a disabling type of self-evaluation triggered by repeated episodes of debilitating pain. This exploratory study experimentally tested the effect of an activated sense of defeat, as well as its interaction with pain catastrophizing, on pain and mood. Participants (N = 71) were allocated to either high or low pain catastrophizing groups and then randomly assigned to receive either defeat or neutral manipulations. A cold pressor task administered before and after the thought manipulation measured pain threshold, alongside visual analogue scales for mental defeat, attention, pain intensity, pain anticipation as well as mood. Thought manipulation checks supported successful defeat activation. Defeat activation was associated with increased negative mood and attentional disengagement from the nociceptive stimuli, irrespective of pain catastrophizing tendency. There were no changes in pain threshold, pain or pain anticipation ratings. The results suggest that mental defeat can be experimentally activated using an autobiographical memory task and that an activated sense of defeat appears to operate independently from pain catastrophizing in influencing mood and attentional disengagement from the nociceptive stimuli. Future research can utilize our experimental approach to evaluate the effect of an activated sense of mental defeat in people with chronic pain, for whom the magnitude of pain, mood and attentional responses may be stronger and broader.
