Area of Science:

  • Psychology
  • Clinical Hypnosis Research

Background:

  • The term "trance" is widely used by clinicians but lacks a standardized operational definition.
  • Subjective experiences during hypnosis are complex and difficult to quantify.

Purpose of the Study:

  • To develop a psychophenomenological method for operationalizing the concept of hypnotic trance.
  • To establish quantitative and qualitative measures for assessing subjective trance experiences.

Main Methods:

  • Operationalized "trance" using hypnotic depth (quantitative measure via predicted Harvard Group Scale score) and "trance typology profiles" (qualitative differentiation).
  • Employed regression analysis for quantitative measures and cluster/discriminant analyses for qualitative profiles.
  • Utilized a psychophenomenological approach to bridge subjective experience and empirical data.

Main Results:

  • Developed a quantitative measure of hypnotic depth (pHGS score) through regression analysis.
  • Identified empirically derived categories of subjective trance experiences using cluster and discriminant analyses, termed "trance typology profiles."
  • Established a framework for differentiating subjective trance experiences.

Conclusions:

  • The proposed psychophenomenological method provides a means to operationalize the concept of hypnotic trance.
  • This approach has significant theoretical and clinical implications for understanding and utilizing hypnosis.
  • Offers a foundation for a more precise and empirically grounded definition of trance in clinical hypnosis.
