Extinction-based protocols such as exposure-in-vivo successfully reduce pain-related fear in chronic pain conditions, but return of fear and clinical relapse often occur. Counterconditioning is assumed to attenuate return of fear, likely through changing the negative affective valence of the conditioned stimulus (CS). We hypothesized that counterconditioning would outperform extinction in mitigating return of pain-related fear, and decrease CS negative affective valence.Healthy participants performed a conditioning task, in which two joystick movements (CSs+) were paired with a painful electrocutaneous stimulus (unconditioned stimulus; pain-US), whereas two other movements (CSs-) were not. Subsequently, in the extinction group, one CS+ was extinguished (pain-US omission) and the other not, whereas in the counterconditioning group, one CS+ was presented with a US of opposite valence (reward-US) and the other was paired with both USs. We tested reinstatement of pain-related fear after two unsignalled pain-US presentations. Results showed no group differences in fear reduction and no differences in CS affective valence changes between the extinguished and counterconditioned CS. Remarkably, none of the groups showed reinstatement. Overall, counterconditioning did not appear to be more effective than extinction in reducing pain-related fear and its return.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
