Clinical Hypnosis in Health Care and Treatment

Beyond standard treatment: A qualitative descriptive study of cancer patients' perceptions of hypnotherapy in cancer care

BACKGROUND AND PURPOSE

Cancer remains a leading cause of death in Australia. The number of new cancer cases diagnosed each year is expected to surpass 200,000 by 2033. This marks a significant increase from about 88,000 cases in 2000 to an estimated 165,000 cases in 2023. Despite advancements in treatment, emotional and psychological challenges in cancer care are often overlooked. This study focuses on hypnotherapy, a complementary therapy recognized for its efficacy for physical and emotional symptoms, yet underutilized in Australian cancer care. The research aims to explore patients' perceptions of hypnotherapy and identify barriers to its integration, contributing to the development of holistic, patient-centered cancer care models.

MATERIALS AND METHODS

A qualitative study employing semi-structured interviews was conducted with 14 adult cancer patients (breast, lung, and colorectal) undergoing active treatment, selected through convenience sampling. The interviews were carried out from May 2022 to August 2023, focusing on participants' experiences and attitudes toward hypnotherapy among other complementary and alternative medicine (CAM) therapies. Thematic analysis using Braun and Clarke's six-step framework was applied to the data.

RESULTS

Five themes were developed following analysis: 1) emotional roller coaster of cancer diagnosis, 2) participants' perspectives on hypnotherapy among other CAM modalities, 3) hypnotherapy as a psychological vs physiological support, 4) fringe benefits of hypnosis, and 5) the main hurdles: cost and lack of information. Participants expressed a diverse range of experiences and attitudes towards hypnotherapy and CAM, with a strong emphasis on the need for emotional support in cancer care. Although hypnotherapy was recognized for its potential to address both emotional and physical symptoms, its predominant use was for emotional well-being. Participants also highlighted the importance of attitudes and endorsements from healthcare providers in their decision-making process about CAM therapies.

CONCLUSION

The study findings emphasize the need for a more integrative and patient-centered approach in cancer care that includes hypnotherapy as a non-pharmacological intervention for physical and particularly emotional support. Healthcare providers should be aware of the potential value of hypnotherapy and consider patient preferences in their recommendations. In addition, addressing the identified barriers could improve the accessibility and integration of hypnotherapy into cancer care protocols in Australia.

French Norms for a Shortened Online Adaptation of the Harvard Group Scale of Hypnotic Susceptibility, Form A

This study presents the norms and psychometric properties for a shortened online adaptation of a French version of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). Assessment of involuntariness and subjective intensity was added to the traditional scoring. A total of 373 individuals completed an online hypnotizability screening test on their own computer. Participants received the HGSHS:A script through an audio recording lasting about 30 minutes. The results showed that the item difficulty and reliability of the short online HGSHS:A were consistent with the offline version of the scale and with the reference samples. Involuntariness and subjective intensity corrections improved significantly the accuracy in the measurement of the scale and helped to dissociate between different phenomenologies in hypnotic responding. These findings indicate that the short online HGSHS:A is a reliable tool for measuring hypnotizability. Moreover, we suggest that using complementary measures of involuntariness and subjective intensity helps to shed more light on hypnotizability as part of a multi-componential approach to hypnotic response.

Real-time assessment of hypnotic depth, using an EEG-based brain-computer interface: a preliminary study

OBJECTIVE

Hypnosis can be an effective treatment for many conditions, and there have been attempts to develop instrumental approaches to continuously monitor hypnotic state level ("depth"). However, there is no method that addresses the individual variability of electrophysiological hypnotic correlates. We explore the possibility of using an EEG-based passive brain-computer interface (pBCI) for real-time, individualised estimation of the hypnosis deepening process.

RESULTS

The wakefulness and deep hypnosis intervals were manually defined and labelled in 27 electroencephalographic (EEG) recordings obtained from eight outpatients after hypnosis sessions. Spectral analysis showed that EEG correlates of deep hypnosis were relatively stable in each patient throughout the treatment but varied between patients. Data from each first session was used to train classification models to continuously assess deep hypnosis probability in subsequent sessions. Models trained using four frequency bands (1.5-45, 1.5-8, 1.5-14, and 4-15 Hz) showed accuracy mostly exceeding 85% in a 10-fold cross-validation. Real-time classification accuracy was also acceptable, so at least one of the four bands yielded results exceeding 74% in any session. The best results averaged across all sessions were obtained using 1.5-14 and 4-15 Hz, with an accuracy of 82%. The revealed issues are also discussed.

Definition and refinement of HYlaDO, a self-hypnosis training program for chronic pain management: A qualitative exploratory study

One in four Canadians is affected by chronic pain, frequently treated with opioids, which present a risk of addiction and overdose. The development of non-pharmacological interventions is therefore crucial. In a pilot project, a self-hypnosis training program showed encouraging results in improving breast cancer patients' quality of life. Based on this program, we developed a new self-hypnosis program for chronic pain patients: HYlaDO (Hypnosis of pain in French, HYpnose de la DOuleur). To structure the process of adapting an existing program to a new context, we used the ORBIT model (Obesity-Related Behavioral Intervention Trials), which consists of four development phases. This study aimed to collect patients' opinions and recommendations, and to refine HYlaDO (ORBIT Phase Ib). Fifteen participants took part in individual semi-structured interviews about this program. Two analysts coded the verbatims, and a thematic categorization was performed. Six themes emerged: practice training, expected vs. perceived effects, chronic pain management, individual practice, satisfaction, and participants' recommendations. Improvements to be considered in this type of program were finally discussed.
