This study examined the relationship between the Hypnotic Induction Profile (HIP) and several psychological tests: Tellegen Absorption Scale (TAS), Spontaneity Assessment Inventory-Revised (SAI-R), Dissociative Experiences Scale (DES), Short-Form Boundary Questionnaire (SFBQ), Mini Locus of Control (MLOC), Testoni Death Representation Scale (TDRS), and the Interpersonal Reactivity Index (IRI). Two hundred and forty volunteers were administered the above tests; 78 of them were also administered the HIP, and its scores were compared to those on the other tests. A significant correlation was found among the TAS, DES, SFBQ and IRI. The HIP was significantly correlated to the DES (r = .19 p1tail = .045), and the IRI-c subscale (r = .19 p1tail = .044); 14 test items from DES, IRI, TAS, SAIR, and SFBQ were also significantly related to the HIP. The findings suggest that hypnotizability may relate to stronger perception of the inner world, decreased aptitude for managing memory processing, and increased sensitivity and empathy.
Hypnosis has had a gradual conceptual emergence from an alleged mystical experience, to sleep, to a psychological shift in concentration that activates a preexisting neuro-physiological circuitry. Data is presented to support the thesis that hypnotizability exists on a spectrum that has biological as well as psycho-social components. When there is synchrony between the bio-psycho-social components of hypnotizability as measured by the Hypnotic Induction Profile (an intact flow), psychotherapy is the primary treatment strategy, with medication secondary or not at all. When measurement reveals a lack of synchrony between biological factors as measured by the eye-roll sign and psycho-social responsivity (a nonintact flow), medication will be primary, with different degrees of psycho-social support.
