AbstractAmong the methods for cognitive control of pain, the suggestions for analgesia-direct or indirect-have been widely and successfully used in experimental and clinical trials. The primary aim of this study was to contribute to the debate about the difference in the effectiveness of indirect and direct suggestions for the management of experimental pain in the ordinary state of consciousness. The secondary aim of the study was to ascertain the role of hypnotizability and expectation of pain relief in the suggestions' effect. A sample of 65 healthy participants with different levels of direct (Harvard Group Scale of Hypnotic Susceptibility: A score) and indirect suggestibility level (Alman-Wexler Indirect Hypnotic Susceptibility Scale score) and different levels of declared expectation of pain relief was submitted to direct and indirect suggestions for analgesia during cold pressure test. The results showed that both direct and indirect suggestions increase the threshold of experimental pain and that the expectation of pain relief is relevant only to the effect of direct suggestions. PERSPECTIVE: Although the reported findings cannot be extended to clinical pain, they suggest that indirect suggestions can be effective independently from the expectation of pain relief, thus evading the possible negative effects of traits such as catastrophism or reactance. Thus, indirect suggestions should be preferred in clinical contexts.Copyright © 2024. Published by Elsevier Inc.
