Hypnosis in patients with perceived stress - a systematic review

The relevance of outcome expectations in group hypnosis for stress reduction: a secondary analysis of a multicenter randomized controlled trial

Background

There is evidence that patients' positive outcome expectations prior to study interventions are associated with better treatment outcomes. Nevertheless, to date, only few studies have investigated whether individual outcome expectations affect treatment outcomes in hypnosis.

Objective

To examine whether outcome expectations to hypnosis prior to starting treatment were able to predict perceived stress, as measured on a visual analog scale (VAS), after 5 weeks.

Methods

We performed a secondary data analysis of a multicenter randomized controlled trial of intervention group participants only. Study participants with stress symptoms were randomized to 5 weekly sessions of a group hypnosis program for stress reduction and improved stress coping, plus 5 hypnosis audio recordings for further individual practice at home, as well as an educational booklet on coping with stress. Perceived stress for the following week was measured at baseline and after 5 weeks using a visual analog scale (0-100 mm; VAS). Hypnosis outcome expectations were assessed at baseline only with the Expectations for Treatment Scale (ETS). Unadjusted and adjusted linear regressions were performed to examine the association between baseline expectations and perceived stress at 5 weeks.

Results

Data from 47 participants (M = 45.02, SD = 13.40 years; 85.1% female) were analyzed. Unadjusted (B = 0.326, t = 0.239, p = 0.812, R2 = 0.001) and adjusted (B = 0.639, t = 0.470, p = 0.641, R2 = 0.168) linear regressions found that outcome expectations to hypnosis were not associated with a change in perceived stress between baseline and after 5 weeks in the intervention group.

Conclusion

Our findings suggest that the beneficial effect of group hypnosis in distressed participants were not associated with outcome expectations. Other mechanisms of action may be more important for the effect of hypnosis, which should be explored in future research.Clinical trial registration: ClinicalTrials.gov, identifier NCT03525093.

Is sleep quality a moderated mediator between perceived stress and depression among stroke patients?

Background

Sleep quality can offer new insights into addressing depression among stroke patients. However, the current understanding of the mechanism by which sleep quality reduces depression is not clear in existing research.

Objectives

This study aimed to identify the relationships and mechanisms among perceived stress, sleep quality, social support, and depression in stroke patients.

Methods

A multicenter cross-sectional study was conducted from January to May 2023. Cluster random sampling was used to recruit 500 stroke patients from five hospitals in Henan Province, China. The Chinese Perceived Stress Scale (CPSS), Pittsburgh Sleep Quality Index (PSQI), Social Support Rating Scale (SSRS), and Hamilton Depression Scale (HAMD-24) were employed to assess perceived stress, sleep quality, social support, and depression, respectively. Data were analyzed using descriptive analysis, Pearson's correlation analysis, and moderated mediation analysis. The study adhered to the STROBE checklist for reporting.

Results

Out of 500 participants, 471 completed the survey (94.2%). After controlling for sex and age, mediation analysis revealed that poor sleep quality partially mediated the relationship between perceived stress and depression (β = 0.184, 95% CI: 0.110, 0.359). Additionally, social support played a moderating role in the mediation model.

Conclusion

This study explained the moderated mediation of sleep quality and social support between perceived stress and depression. It provided a theoretical basis for the development of a sleep quality intervention program for reducing depression among stroke patients.

Randomized controlled trial investigating potential effects of relaxation on mitochondrial function in immune cells: A pilot experiment

This study aimed to investigate the effect of a relaxation response induced by hypnosis on the mitochondrial energy production of immune cells compared to an everyday relaxing situation. Chronically stressed individuals (88% women) with at least moderate suggestibility were randomized to a hypnosis (20 min relaxation hypnosis; n = 20) or a control condition (20 min documentary; n = 22). Before and after intervention, peripheral blood was collected. The primary outcomes were mitochondrial respiration and density in immune cells measured by high-resolution respirometry and citrate synthase activity assays. As secondary outcome, perceived stress, anxiety, and depressive mood were assessed. The intervention led to no significant Group × Time effects on mitochondrial bioenergetic parameters but a significant Time effect (ηp2 = .09 -.10). Thus, there were no differences in the experimental conditions concerning the measured parameters of mitochondrial bioenergetics. Exploratory subanalyses indicated that stress, anxiety, and depressive mood were linked to lower mitochondrial respiration. Individuals with higher anxiety had less decrease in routine respiration over time than those with lower anxiety (ηp2 = .09). This study explores the effects of relaxation in the form of hypnosis compared to watching a video on the energy metabolism of immune cells. Relaxation, whether in targeted (hypnosis) or untargeted (documentary) form, affected mitochondrial respiration. Further research should focus on the long-term effects of relaxation on bioenergetics. The trial was retrospectively registered on 07/12/2021, DRKS00027356, https://drks.de/search/de/trial/DRKS00027356.

Psychosocial effects of hypnosis in patients with obesity: a pilot randomized controlled trial

The usefulness of hypnosis in patients with obesity needs to be better understood in terms of various outcomes, in addition to weight loss. The aim of this research was to investigate the effects of hypnosis and self-hypnosis in combination with nutrition education for patients with obesity, as opposed to nutrition education alone, on the secondary outcomes of quality of life (QoL), coping strategies, and self-esteem within a randomized controlled trial (RCT). Eighty-two participants were included in this study (84.3% were women), with 41 in each group. Further, 70 participants had completed treatment. The intervention consisted of eight group sessions (about one every two weeks). Participants completed self-reported questionnaires assessing their QoL, coping strategies, and self-esteem (SF-36, CISS, SEI) before and after the intervention. Non-parametric analyses were performed. Both groups had comparable characteristics at inclusion (sociodemographic information, clinical information, and scores for the self-reported scales). At eight months (i.e. two months after intervention completion), patients from the hypnosis group used more task-oriented coping (p < .001), less emotion-oriented coping (p < .01) and distraction (p < .05), and had more energy/less fatigue (p < .001) compared to the group who did not undergo hypnosis. Other improvements were observed in the hypnosis group, but there were no significant differences compared with the non-hypnosis group in terms of QoL dimensions and general self-esteem. In conclusion, hypnosis and self-hypnosis in combination with nutrition education seem to be promising interventions to help patients deal with obesity, especially by improving their coping strategies.

Feasibility and acceptance of self-hypnosis to reduce chronic stress levels on family in-home caregivers of elderly people: protocol for the POSSAID pilot, randomised, wait-list controlled trial

INTRODUCTION

Family members who care for elderly people experience high levels of chronic stress because of the intensive assistance they provide permanently to those who are losing their autonomy. Often considered a burden, this stress causes serious consequences to their health and worsens their quality of life (QoL). Reducing caregivers' chronic stress via self-hypnosis protocols may be an effective treatment. The objective is to evaluate the feasibility and acceptance of self-hypnosis protocols taught by hypnotherapy-trained nurses to reduce the chronic stress of in-family caregivers.

METHODS AND ANALYSIS

This study is a prospective, monocentric, non-blinded, parallel, pilot, randomised waitlist-controlled trial that will be conducted at the University Hospital of Reunion Island. Sixty participants will be randomly allocated to one of two groups: a self-hypnosis group (intervention) or a waitlist control group. After an 8-week training programme, intervention participants will practice self-hypnosis for ten minutes/day over 8 weeks and subsequently be followed up for 16 weeks thereafter. The primary outcome is to assess the feasibility of a 16-week self-hypnosis protocol for in-family caregivers. Secondary outcomes include the evaluation of the effects of practising self-hypnosis among in-family caregivers of elderly people concerning their stress levels, sleep disorders, levels of fatigue, and QoL at 2, 4 and 8 months on an exploratory basis.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Institutional Ethics Committee CPP Ile de France VI-Groupe Hospitalier Pitié Salpêtrière on 14 April 2021 (ID RCB: 2021-A00009-32). All participants will receive information about the trial in verbal and written forms. They will give an oral consent which is notified in a dedicated research file prior before enrolment. Results will be published in peer-reviewed journals as well as presented and disseminated at conferences.

The Effects of a Single Relaxation Hypnosis Session on Mental Stress in Chronically Stressed Individuals

Abstract. Background: Chronically stressed people often suffer from anxiety and depressive mood. Hypnosis is a technique that can induce a relaxation response and reduce negative stress symptoms. Objective: This explorative study investigated the impact of a single relaxation hypnosis session on stress-related psychological symptoms. Method: 47 suggestible, stressed individuals (87 % female) were randomized to a hypnosis group ( n = 23, 20-minute hypnosis) or a control group ( n = 24, 20-minute scientific documentary). Before and after the intervention, we assessed perceived stress, negative affect, anxiety, and depressive mood. Results: After the hypnosis intervention, depressive mood ( d = 0.36) and state anxiety ( d = 1.00) decreased, while negative affect remained stable ( d = 0.04). Perceived stress was reduced in both groups. Conclusion: A single relaxation hypnosis session decreased stress-related symptoms in chronically stressed individuals. Our results substantiated the stress-alleviating effects of hypnosis.

Occupational Health and Safety Receptivity towards Clinical Innovations That Can Benefit Workplace Mental Health Programs: Anxiety and Hypnotherapy Trends

Anxiety is one of the most common mental health conditions experienced by people in Australia during their working years according to the Australian Bureau of Statistics (ABS) and employers recognising that mental health impacts their organisation’s bottom line are increasingly interested in programs to promote better mental health, well-being, and productivity. Beyond management concern for productivity, statutory protection is necessary to safeguard mental health, under the Australian Occupational Health and Safety (OHS) Act, organisations have a duty to eliminate or minimise risks to psychological (mental) health by designing effective workplace systems and Occupational Health and Safety (OHS) practitioners are central to the design and responsibility in managing these systems. Despite literature indicating the benefits of OHS workplace mental health initiatives, such as improved overall health, reduced absenteeism, increased job satisfaction and morale, there remains a lack of empirical research around program measurement, and their effectiveness in this area has been brought into question. The OHS function is interested in improving research around the relationship and connection between work performance and mental health but: there are few studies regarding performance outcomes of mental health OHS services within management journals and insufficient information around the prevalence of psychological morbidity in the workplace and its impact. The purpose of this study was to assess OHS perception regarding anxiety and reveal perceptions and receptivity towards alternative therapies and solutions being used in clinical practice to deal with anxiety such as cognitive behavioural therapy (CBT) with a focus on Hypnotherapy.

systematic review on role of hypnotherapeutic intervention in promoting positive psychological health

In this world of fast moving day to day activities, it is of utmost importance that every individual is aware of their personal well- being and take steps towards improving these over the course of time (Al-Asmi et al., 2015; Amato et al., 2001). The state of well – being can be described as understanding the quality of life led by various individuals (Statham & Chase, 2010). The concept of well- being in humans is broadly classified into two aspects - the first one is associated with having life satisfaction and a positive effect in one’s life.the study here is only focused towards the use of hypnotherapeutic interventions in the process of promoting a positive psychological heath scenario all across. The study undertakes a systematic review approach with 51 articles and aims to put forward a summarised version of the literature in the aspect of  hypnotherapeutic interventions.The result of the study identifies a total of three themes from the systematic literature review conducted. It is found that the three identified themes have been put forward by researchers as the most effective impact of hypnotherapeutic interventions. 

Guidelines for the Assessment of Efficacy of Clinical Hypnosis Applications

Research on the efficacy of hypnosis applications continues to grow, but there remain major gaps between the science and clinical practice. One challenge has been a lack of consensus on which applications of hypnosis are efficacious based on research evidence. In 2018, 6 major hypnosis organizations collaborated to form the Task Force for Establishing Efficacy Standards for Clinical Hypnosis. This paper describes a Guideline for the Assessment of Efficacy of Clinical Hypnosis Applications developed by the Task Force, which makes 10 specific recommendations. The guideline is intended to be a tool for those who want to assess the quality of existing evidence on the efficacy of clinical hypnosis for any particular indication. The paper also discusses methodological issues in the interpretation and implementation of these guidelines. Future papers will report on the other products of the Hypnosis Efficacy Task Force, such as best practice recommendations for outcomes research in hypnosis and an international survey of researchers and clinicians on current practice and attitudes about hypnosis.

Pilot Study of a Brief Hypnotic Induction: Effects on Blood Pressure, Heart Rate, and Subjective Distress in Patients Diagnosed with Hypertension

The feasibility of hypnotherapy interventions for lowering blood pressure and psychological stress in hypertensive patients was investigated in a pilot study. The research objective was to determine the effect of audio hypnotherapy on blood pressure, stress levels, and heart rate in primary hypertension patients. The study randomized 64 hypertensive patients to the intervention or usual care. The intervention group received hypnotherapy through audio recordings for 15 minutes, while the control group took a rest for about 15 minutes. Blood pressure and heart rate were measured with digital tensimeter and stress levels with the Subjective Units of Distress Scale. Data analysis used Kruskal Wallis Test. The results showed a significant difference between the intervention and control groups with p value < .001 for decreasing in systolic blood pressure and p value < .001 for decreasing in stress levels. This pilot study suggests that a hypnotherapy intervention may be feasible and of benefit in a clinical population of hypertensive patients, however further study is needed.

The effectiveness of cognitive developmental hypnotherapy on differentiation of self, meaning in life and marital conflicts in married women

The aim of the present study is to investigate the effectiveness of Cognitive Developmental Hypnotherapy (CDH) on Differentiation of Self, Meaning in Life and Marital Conflicts in married women. The method is quasi-experimental pretest and posttest with a control group. The statistical population of this study includes married women who came to FUM Counseling and Psychological Services Center to receive psychological services. The sample of this study included 40 married women who were selected by targeted sampling method and randomly assigned to two experimental and control groups. Participants in the pretest and posttest study answered the Differentiation of Self Inventory, the Marital Conflicts questionnaire by Sanaei, and the Meaning in Life questionnaire. The research data were analyzed using ANCOVA and MANCOVA with SPSS-21. The findings showed CDH led to an increase in Differentiation of Self and Meaning in life, and a reduction in Marital Conflicts in women. Accordingly, CDH through using techniques such as induction and empowerment of the Ego is effective in marital conflicts of married women. Therefore, using it as a means to improve the quality of married women's lives is recommended.

Clinical Hypnosis For Pain Reduction In Breast Cancer Mastectomy: A Randomized Clinical Trial

Surgical procedures for breast cancer treatment are commonly followed by pain. Clinical hypnosis has been shown to be effective in reducing pain during and after surgery, but most of the studies have used analogical scales, which only measure pain intensity. The aim of this study was to evaluate the effect of clinical hypnosis on pain intensity and its interference in daily activities in patients before and after mastectomy. The patients were evaluated using the Brief Pain Inventory. Forty patients were randomly assigned to an experimental or control group and evaluated 5 times: 1) baseline, 2) after clinical hypnosis session, 3) before surgery, 4) 1 day after surgery, and 5) 1 week after the surgery (follow-up). The results showed that after surgery the hypnosis group had a statistically significant reduction in pain intensity, less interference of pain with daily activities, sleep and life enjoyment compared with a control group. Clinical hypnosis may be recommended as a complementary treatment procedure for postmastectomy pain reduction and improving the quality of life of these patients.

Bispectral Index Alterations and Associations With Autonomic Changes During Hypnosis in Trauma Center Researchers: Formative Evaluation Study

BACKGROUND

Previous work performed by our group demonstrated that intermittent reductions in bispectral index (BIS) values were found during neurofeedback following mindfulness instructions. Hypnosis was induced to enhance reductions in BIS values.

OBJECTIVE

This study aims to assess physiologic relaxation and explore its associations with BIS values using autonomic monitoring.

METHODS

Each session consisted of reading a 4-minute baseline neutral script and playing an 18-minute hypnosis tape to 3 researchers involved in the BIS neurofeedback study. In addition to BIS monitoring, autonomic monitoring was performed, and this included measures of electromyography (EMG), skin temperature, skin conductance, respiratory rate, expired carbon dioxide, and heart rate variability. The resulting data were analyzed using two-tailed t tests, correlation analyses, and multivariate linear regression analyses.

RESULTS

We found that hypnosis was associated with reductions in BIS (P<.001), EMG (P<.001), respiratory rate (P<.001), skin conductance (P=.006), and very low frequency power (P=.04); it was also associated with increases in expired carbon dioxide (P<.001), skin temperature (P=.04), high frequency power (P<.001), and successive heart interbeat interval difference (P=.04) values. Decreased BIS values were associated with reduced EMG measures (R=0.76; P<.001), respiratory rate (R=0.35; P=.004), skin conductance (R=0.57; P<.001), and low frequency power (R=0.32; P=.01) and with increased high frequency power (R=-0.53; P<.001), successive heart interbeat interval difference (R=-0.32; P=.009), and heart interbeat interval SD (R=-0.26; P=.04) values.

CONCLUSIONS

Hypnosis appeared to induce mental and physical relaxation, enhance parasympathetic neural activation, and attenuate sympathetic nervous system activity, changes that were associated with BIS values. Findings from this preliminary formative evaluation suggest that the current hypnosis model may be useful for assessing autonomic physiological associations with changes in BIS values, thus motivating us to proceed with a larger investigation in trauma center nurses and physicians.

A Case of Acute Stress in Post-hypnotized Patient

Background: Mental health conditions that can occur immediately after a traumatic event is called acute stress reaction; in this case, happens after hypnosis. This can cause a variety of psychological symptoms without attention or treatment, causesost-traumatic stress disorder. The psychological symptoms can negatively affect the quality of life, especially the reactions arise after a traumatic event that after being hypnotized. Hypnosis works by changing the activity in brain regions associated with attention or alertness. At the time hypnotised, we saw a very high level of concentration, so that suggestions given to him will be more easily accepted. Case Report: The case presented is the hypnotic impact of acute stress reactions. A woman named Mrs. J 63 years old. The Karo tribe who experienced anxiety, fear, and difficulty sleeping after experiencing hypnosis four days ago. This experienced it after being hypnotized at home. Conclusion: Hypnosis plays a role in all parts of life involving human mind. Hypnosis is a science that exploits the potential mental and hidden in humans, known as the subconscious. in medical health, hypnosis therapy is very important, what we need to realize is that hypnosis with bad intentions can harm humans. Hypnosis incident was reported in patients who suffer from post traumatic stress disorder. found in many women. older women are more vulnerable to acute stress. Previous research has shown that hypnotic susceptibility correlated with personality traits.

General self-efficacy and social support as mediators of the association between perceived stress and quality of life among rural women with previous gestational diabetes mellitus

To explore the association between perceived stress and quality of life (QoL) and the mediating role of general self-efficacy and social support in this association. Gestational diabetes mellitus (GDM) is one of the most common metabolic diseases suffered by pregnant women. Women with previous GDM may experience more medical-related stress and have a lower QoL than those without it. A multisite correlational study. Four hundred sixty-five women with previous GDM living in rural areas in China participated in this study from November 2017 to June 2019. The participants completed a set of self-reported socio-demographic questionnaires, the Perceived Stress Scale, the General Self-Efficacy Scale, the Social Support Rating Scale and the World Health Organization QoL assessment (Brief version). STROBE checklist was used as the guideline for this study. The mean QoL score was 13.97 (SD 2.07) for physical health, 13.75 (SD 1.98) for psychological health, 14.96 (SD 1.99) for social relations and 12.49 (SD 1.74) for environmental conditions. About 43.9% of women with previous GDM reported increased stress, which was negatively correlated with each of these QoL domains. Yet, the negative effect of perceived stress on QoL could be completely or partly mediated by better social support or general self-efficacy among this population. Nearly half of the women in the study living in rural China reported increased stress after delivery, and there is room to improve QoL in the environmental domain among women with previous GDM. Increasing general self-efficacy or social support can help these women avoid the negative effects of perceived stress on their QoL. These findings suggest that healthcare providers need to be cognizant of the importance of self-efficacy and social support for women with previous GDM in both enhancing QoL and reducing the negative impact of perceived stress on QoL.

Group hypnosis for stress reduction and improved stress coping: a multicenter randomized controlled trial

Background

The aim of the trial was to investigate the effect of a hypnotherapeutic group program in healthy persons with increased levels of perceived stress.

Methods

In a randomized controlled multicenter trial participants with a self-assessed subjective stress level ≥ 40 mm on a visual analogue scale (0–100 mm; VAS) for the previous week and a stable state of health were randomized to either 5 weekly sessions of 120-min duration of a hypnotherapeutic group program for stress reduction and improved stress coping plus 5 hypnosis audiorecords for individual practice at home plus an educational booklet for stress coping (hypnosis group) versus an educational booklet only (control group). The primary outcome parameter was the VAS stress level for the previous week after 5 weeks. Secondary outcome parameters included the VAS stress level after 12 weeks, perceived stress (CPSS), depression (ADS-K), self efficacy (SWE) and quality of life (SF 36) after 5 weeks and 12 weeks. Analysis of covariance with a significance level of 5% using the full analysis set was used for analysis; the model included treatment (fixed effect), VAS baseline value (fixed covariate), and center (random effect).

Results

A total of 95 participants were randomized; 47 (40 female, 45 ± 13.4 years of age) were allocated to the hypnosis group, and 48 (41 female, 46.9 ± 14.3 years) were allocated to the control group. Regarding VAS stress level after 5 weeks, the adjusted VAS mean in the hypnosis group was 41.8 mm [95% confidence interval (CI): 35.2; 48.4] compared to 62.9 mm [56.2; 69.7] in the control group, and the group difference was − 21.2 mm [− 30.1; − 12.2] (P < 0.001). After 12 weeks, the stress intensity on the VAS showed a between-group difference of − 14.7 mm [− 25.1; − 4.4] (P = 0.006), and the adjusted means were 41.1 mm [33.4; 48.8] in the hypnosis group and 55.9 mm [48.4; 63.5] in the control group. Improvements were also reported for CPSS, SF-36, SWE and ADS-K after 5 and 12 weeks.

Conclusion

Compared to the control group, the hypnosis group showed reduced perceived stress after 5 and 12 weeks.

Group Hypnosis for Stress Reduction - A Feasibility Study

The aim of this study was to develop a standardized hypnotherapeutic group program for stress reduction, test its feasibility, and measure its preliminary pre- to postintervention effects. In this prospective, single-arm feasibility study, healthy adult participants with self-assessed increased stress levels received 5 weekly group hypnosis sessions plus audio recordings. Twelve persons (10 females, mean (SD) age 48.9 (11.8) years participated. The mean (SD) intensity of perceived stress on a 0-to-100 mm VAS was reduced from 75.5 (11.5) mm at baseline to 33.9 (18.8) mm after 5 weeks. Cohen's perceived stress scale was reduced from 20.8 (5.7) to 13.8 (5.4). Focus group interviews showed that the study intervention was feasible and well accepted. Confirmatory testing of the intervention in a randomized controlled trial is necessary.

Hypnosis Associated with 3D Immersive Virtual Reality Technology in the Management of Pain: A Review of the Literature

Hypnosis is well documented in the literature in the management of acute and chronic pain. Virtual reality (VR) is currently gaining credibility in the same fields as hypnosis for medical applications. Lately, the combination of hypnosis and VR was considered. The aim of this scoping review is to understand the current studied contexts and effects of virtual reality hypnosis (VRH) for the management of pain. We searched on PubMed, Taylor & Francis Online, and ProQuest databases with the following terms: “virtual reality,” “3D,” “hypnosis,” and “pain”. We included 8 studies that combined hypnosis and VR. All articles are in English. Two included healthy volunteers and six are clinical studies. Short-term results indicated significant decreases in pain intensity, pain unpleasantness, time spent thinking about pain, anxiety, and levels of opioids. However, results are not consistent for all patients all the days. VR alone seems to reduce pain independently of the hypnotizability level. One study claimed that VR and hypnosis could alter each other’s effects and another argued that VR did not inhibit the hypnotic process and may even facilitate it by employing visual imagery. We cannot affirm that VR added value to hypnosis when they are combined. These trials and case series gave us indications about the possible applications of VRH in different contexts. Additional randomized clinical trials on VRH in the future will have to test this technique in clinical practice and help define guidelines for VRH utilization in pain management.

Can hypnosis and virtual reality reduce anxiety, pain and fatigue among patients who undergo cardiac surgery: a randomised controlled trial

Background

Different non-pharmacological techniques, including hypnosis and virtual reality (VR) are currently used as complementary tools in the treatment of anxiety, acute and chronic pain. A new technique called virtual reality hypnosis (VRH), which encompasses a combination of both tools, is regularly used although its benefits and underlying mechanisms remain unknown to date. With the goal to improve our understanding of VRH combination effects, it is necessary to conduct randomised and controlled research trials in order to understand their clinical interest and potential benefits.

Methods

Patients (n = 100) undergoing cardiac surgery at the Liège University Hospital will be randomly assigned to one of four conditions (control, hypnosis, VR or VRH). Each patient will receive two sessions of one of the techniques: one the day before the surgery and one the day after. Physiological assessments will be made on the monitor and patients will rate their levels of anxiety, fatigue, pain, absorption and dissociation.

Discussion

This study will help to expand knowledge on the application of virtual reality, hypnosis and VRH in the specific context of cardiac and intensive care procedures, and the influence of these non-pharmacological techniques on patient’s anxiety, fatigue, pain and phenomenological experience.

The Unease Modulation Model: An Experiential Model of Stress With Implications for Health, Stress Management, and Public Policy

Stress has a pervasive, global, and negative influence on individual health. Stress also has negative effects on families, organizations, and communities. Current models of stress are either too general or too detailed to guide effective interventions across the spectrum of medical and social conditions that are stress-related. A new model is needed that explains how stress can have such varied effects and describes how to reduce its harm. The model must also capture both the dynamic nature of stress and its ability to persist and cause chronic effects. The model must guide those who use it in selecting effective interventions and in developing more effective interventions. Ideally, the model will be helpful to people who are experiencing stress and do not have access to professional help. The authors propose a model in an attempt to address the above concerns. The proposed model is called the Unease Modulation Model (UM Model). Briefly, the UM Model separates stress into several elements common to people's experience. The model describes how these elements interact and how those interactions lead to recurring states that are associated with health or illness. Finally, the model enables the person under stress to identify the elements where they will have the most leverage to evoke change and apply specific, effective techniques for that purpose. While the model is experiential, it is also based on mathematical theories of perception, nonlinear dynamics, neurophysiology, and cognitive psychology. In spite of this underlying sophistication, it can be used by those without a medical education. The proposed model has been taught successfully to patients in a clinical setting. The model is now being used in an international training program with police officers to address the long-term stress associated with the career and reduce decision-making errors regarding use of force. This article introduces the model by defining components based on patient descriptions of stress and integrating those into a formal structure. We then demonstrate how the model can be applied to a number of medical and psychiatric conditions. The article concludes by briefly discussing the model's application to family and societal stress-related difficulties.
