Although the belief that hypnotizability is a mental dysfunction has been refuted over time, there is still research today that seeks to explore and clarify this preconception. The results of recent research indicate that, on the contrary, greater psychopathology is more frequent in subjects with low hypnotic susceptibility. Using the Stanford Hypnotic Susceptibility Scale type A (SHSS-A) for hypnotizability, Symptom Checklist-Revised (SCL-90-R) for psychopathology, and the Somatosensory Amplification Scale (SSAS) and Toronto Alexithymia Scale (TAS-20) for psychosomatic dimensions, we found no relationship between baseline psychopathology, alexithymia and hypnotizability in 69 subjects with chronic pain in this retrospective observational study. Psychopathology did not affect the 2-month outcomes of hypnotic suggestions for pain in terms of either pain (assess using Italian Pain Questionnaire), anxiety or depression (assessed through Hospital Anxiety and Depression Scale) scores. Furthermore, i) no relationships were found between hypnotizability and degree of either psychopathology or alexithymia, definitively eliminating any doubts about the belief that hypnosis is a mental dysfunction; ii) only single hypnotic phenomena (SHSS-A) could be linked to some psychopathological dimensions; iii) analgesia suggestions also acted on anxiety and depression; and iv) the use of hypnotic suggestions for analgesia revealed a close relationship between improvements in sensorial and evaluative dimensions of pain and mitigation of anxiety. Hypnosis thereby seems to be a powerful tool in psychosomatic medicine whose effects on mind and body are inextricably linked.
