The role of self-efficacy expectancies in the prediction of pain tolerance.

The association of self-efficacy expectancies with pain tolerance on the cold pressor test was examined during treatment conditions of setting quotas alone and in conjunction with monetary reinforcement and placebos in 64 college volunteers. It was found that quota setting was an effective means of increasing cold pressor pain tolerance. The addition of monetary reinforcement of quota achievement did not enhance performance, while the addition of a placebo decreased the effectiveness of quota setting. Self-efficacy expectancies were significantly correlated with pain tolerance times and were better predictors of tolerance than pain ratings. Self-efficacy expectancies and pain tolerance times at treatment were both found to predict 1 week follow-up performance.
