Randomized Controlled Trial Multicenter Study
Anger management style and endogenous opioid function: is gender a moderator?
This study explored possible gender moderation of previously reported associations between elevated trait anger-out and reduced endogenous opioid analgesia. One hundred forty-five healthy participants underwent acute electrocutaneous pain stimulation after placebo and oral opioid blockade in separate sessions. Blockade effects were derived reflecting changes in pain responses induced by opioid blockade. ⋯ The anger-in/opioid association was partially due to overlap with anger-out, but the converse was not true. These findings provide additional evidence of an association between trait anger-out and endogenous opioid analgesia, but further suggest that gender may moderate these effects. In contrast to past work, anger-in was related to reduced opioid analgesia, although overlap with anger-out may contribute to this finding.
