Situational but Not Dispositional Pain Catastrophizing Correlates With Early Postoperative Pain in Pain-Free Patients Before Surgery

Pain catastrophizing may be assessed as a dispositional measure using a previous painful experience as a reference or as a situational measure using an actual ongoing pain as a reference. The latter has shown more robust correlations with pain-related outcomes; the relative influence of dispositional and situational pain catastrophizing remains unknown in relation to populations with no pain before surgery. Forty-two consecutive patients who underwent corrective surgery for funnel chest were asked to complete the Pain Catastrophizing Scale with reference to 1) a previous painful experience (dispositional pain catastrophizing), 2) experimental pain during a 2-minute cold pressor test (situational experimental pain catastrophizing), and 3) clinical pain 3 days after surgery (situational clinical pain catastrophizing) to investigate whether these measures predicted immediate pain intensity and unpleasantness in the early postoperative period. Thirty-four patients were available for analyses. Dispositional pain catastrophizing was unrelated to situational experimental and situational clinical pain catastrophizing and to postoperative pain and unpleasantness (P > .05). In contrast, the 2 situation-specific pain catastrophizing measures were strongly associated (p = .59, P = .0002). In analyses adjusted for preoperative anxiety, depression, and cold pressor pain sensitivity, situational experimental and situational clinical pain catastrophizing correlated with postoperative movement-evoked pain (beta = 1.36, P = .01 and beta = 1.24, P = .02, respectively) and unpleasantness (beta = 1.32, P = .01 and beta = 1.36, P = .01, respectively).
