Confirmatory Factor Analysis of the Elkins Hypnotizability Scale in a Clinical Population.

The objective of this study was to determine the best-fit factor structure of a standardized hypnotizability measure in a clinical population. The Elkins Hypnotizability Scale (EHS) was administered to 173 post-menopausal women, age from 39 to 75 years, with a mean age of 54.61 years. Confirmatory factor analysis was conducted, and comparative fit index (CFI) and root mean square error of approximation (RMSEA) were used to determine goodness of fit. Results indicated that the single-factor structure modeled with six indicators based on the individual items on the EHS provides the best description of fit. Results of the present study demonstrate that the EHS has a single-factor structure. Further research is required with other populations and measures.

Reliability and Validity of the Elkins Hypnotizability Scale within a Clinical Sample.

Hypnotherapy is used in clinical settings to treat mental and physical health-related conditions. Hypnotic response can be measured through hypnotizability scales to help interventionists personalize treatment plans to suit the patients' individualized hypnotic abilities. Examples of these scales are the Elkins Hypnotizability Scale (EHS) and the Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C). According to the previous literature, these scales have good discriminating ability and internal consistency (α = 0.85) in collegiate samples, but the psychometric properties of the EHS for a targeted clinical population have not been determined yet. This study assessed said properties, and results showed adequate reliability of the EHS in a targeted clinical sample and strong convergent validity of the EHS to the SHSS:C. The authors conclude that the EHS is a strong and useful measure of hypnotizability that is pleasant, safe, brief, and sensible to individualities in hypnotic ability found in diverse clinical samples.

Feasibility of Attention Restoration Theory-Driven Hypnotherapy for Fatigue in Cancer Survivors.

This study aimed to assess the feasibility of Attention Restoration Theory (ART)-driven hypnotherapy to address cancer-related fatigue (CRF). Six participants with CRF completed the study. Participants completed measures of fatigue and pain pre- and posttreatment of 5 sessions of ART-driven hypnotherapy, each of which followed a treatment manual. Results indicate that participants experienced reductions in fatigue, fatigue bothersomeness, and pain following the intervention. Additionally, participants reported high levels of treatment satisfaction. This innovative intervention of ART-driven hypnotherapy appears to be feasible and warrants further study in a controlled trial with a larger sample.
