Personality Styles of Hypnosis-Practicing Dentists: A Brief Report.

This cross-sectional study used the Personality Style and Disorder Inventory (PSDI) via the internet to examine personality styles of random hypnosis society sample groups (German Society of Dental Hypnosis [DGZH, = 418] and Milton Erickson Society of Clinical Hypnosis Germany Listserv [MEG, = 490]) and compared these data of hypnosis practitioners (HYP samples) with 2 control samples of persons not interested in hypnosis (NONHYP samples): 1,027 psychotherapists from DACH countries (Germany, Austria, and Switzerland) and 3,392 people of the normal population of Germany. Results show that HYP-DGZH dentists were much more intuitive/schizotypal (.001), unselfish/self-sacrificing (.001), charming/histrionic (.001) and optimistic/rhapsodic (.001) than the HYP-MEG sample. All HYP-DGZH dentists also showed significantly elevated levels in these four personality styles compared with the levels of the NONHYP-DACH psychotherapists (.001), and elevated levels in intuitive/schizotypal, unselfish/self-sacrificing, and optimistic/rhapsodic compared with the NONHYP normal population. The intuitive/schizotypal values of the HYP-DGZH dentists were predominant. Within the limitations of the study, the presence of a specific personality profile in random samples of dentists who use hypnosis and are members of a professional hypnosis society suggests that a "homo hypnoticus" might also exist among dentists. However, this needs to be investigated in more detail.
