Exposure to stress is associated with poor outcomes in people with chronic pain. Dispositional variables, such as pain catastrophizing and distress intolerance, may impact reactivity to stressors. Importantly, these variables can be modified with treatment. The aim of this study was to investigate whether pain catastrophizing and distress intolerance were associated with tolerance of a pain stressor or a psychosocial stressor, and heightened negative affect following these stressors. A sample of 50 adults with chronic pain completed self-report measures and pain and psychosocial stress inductions. Results indicated that pain catastrophizing was associated with heightened anxiety during pain induction. Distress intolerance was associated with negative affect following a psychosocial stressor, and with poorer tolerance of the psychosocial stressor. Pain catastrophizing and distress intolerance are related factors, however, they exhibit distinct associations with amplification of pain and psychosocial stress reactivity. These variables may be important treatment targets in people with chronic pain.
