Modification of Pain through Covert Positive Reinforcement

Abstract

This study investigated the effectiveness of covert positive reinforcement in modifying response to cold-pressor pain and in increasing the use of prescribed adaptive imagery. 80 women were randomly assigned to covert positive reinforcement, backward conditioning, covert rehearsal, and expectancy conditions. Covert positive reinforcement did not yield either greater pain tolerance and use of adaptive imagery or less subjective discomfort than the other conditions. Modification of pain was not associated with the use of adaptive imagery but was correlated with the clarity of imagery. 64% of the subjects reported using self-generated coping strategies. The results of this study contribute to the body of evidence which does not support the operant conceptualization of covert positive reinforcement.
