Factor analysis of the Elkins Hypnotizability Scale.

Area of Science:

• Psychology
• Neuroscience

Background:

• Hypnotizability assessment is crucial for hypnosis research and clinical applications.
• The Elkins Hypnotizability Scale (EHS) was developed as a brief, reliable measure.
• Previous research supports the EHS's convergent validity with established scales.

Purpose of the Study:

• To examine the factor structure of the Elkins Hypnotizability Scale (EHS).
• To provide empirical support for the EHS's underlying dimensional structure.

Main Methods:

• The EHS was administered to a sample of 252 adult participants.
• Exploratory factor analysis was employed to determine the scale's structure.
• Statistical analyses focused on identifying factors that best fit the data.

Main Results:

• A four-factor structure was identified for the EHS, offering the best theoretical fit.
• These four factors collectively accounted for 63.37% of the observed variance.
• The findings support the EHS as a multidimensional measure of hypnotizability.

Conclusions:

• The study provides an initial empirical factor structure for the Elkins Hypnotizability Scale.
• This factor structure supports the EHS's utility in both clinical and laboratory hypnosis research.
• Further research can build upon this established factor structure for the EHS.
