Suppressing and attending to pain-related thoughts in chronic pain patients.

Attempted suppression of pain-related thoughts was investigated in consecutive referrals for pain management (N = 39). Participants monitored their pain-related thoughts for three 5-min periods. In period 1, all participants were instructed to think about anything. For period 2, participants were instructed to either suppress pain-related thoughts, attend to pain-related thoughts, or to continue to think about anything. In period 3, all participants were again instructed to think about anything. Participants instructed to attend to their pain reported more pain-related thoughts than suppressors and controls in both periods 2 and 3. Suppressors experienced reduced pain-related thoughts during period 2. There was no immediate enhancement or delayed increase.
