Catastrophizing (negative pain-related cognitions) is the most studied psychosocial factor affecting pain interference. To date, however, little research has been conducted on the relationship between mindfulness and catastrophizing in shaping pain experiences. For instance, it is possible that catastrophizing leads to heightened levels of pain interference, but only among specific subgroups of patients, such as those with low levels of mindfulness. The primary objective of this study was to examine the association between dispositional mindfulness, catastrophizing and day-to-day pain interference among a sample of patients with fibromyalgia. Patients with fibromyalgia were asked to report their levels pain interfering with work once a day for a period of 7 days using REDcap (A web-based software application for electronic data collection as well. Multilevel modeling (MLM) analyses indicated that high scores in catastrophizing were associated with heightened levels of pain related work interference (p < .01). Results of a multilevel moderation analysis revealed that the association between catastrophizing and pain related work interference was moderated by mindfulness (p < .05), with patients lower in mindfulness showing a relatively stronger link between catastrophizing and pain related work interference. Catastrophizing and mindfulness appear to influence on another, with high levels of mindfulness buffering the pain related impact of catastrophizing. The theoretical and clinical implications of our findings will be discussed.
