The current study tested the opioid dysfunction hypothesis of anger-out using an alternative index of opioid function: pain-induced changes in plasma endogenous opioids. Plasma beta-endorphin (BE) was assessed at rest and again following exposure to three laboratory acute pain tasks (finger pressure, ischemic, and thermal) in 14 healthy controls and 13 chro...
