“…The emphasis these old masters placed on hypnosis as a diagnostic and prognostic tool was a forerunner of the modern use of hypnotizability assessment of psychotic patients in both laboratory and clinical settings (Hilgard, 1965;Lavoie & Sabourin, 1980;Murray-Jobsis, 1991;Pettinati, 1982;Spiegel et aL, 1982;Spiegel & Spiegel, 1978/1987). In particular, Breukink's concIusion that high hypnotizability in psychotic patients is a good prognostic sign has been supported by modern research (see Lavoie & Elie, 1985; as weU as clinical studies (see Lavoie & Sabourin, 1980;Murray-Jobsis, 1991;Scagnelli, 1976;Scagnelli-Jobsis, 1982;Spiegel & Fink, 1979). It should be noted, however, that a great number of important follow-up studies in the field of schizophrenia indicate that there is a wide range of outcome in schizophrenia (M. Bleuler, 1978Bleuler, , 1983Carpenter, Bartko, Strauss, & Hawk, 1978;Carpenter & Strauss, 1977;Ciompi, 1978;Harding & Brooks, 1984;Harding, Brooks, Ashikaga, Strauss, & Breier, 1987;Huber & Gross, 1980).…”
