Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. Evaluate the effects of an VRH prototype in reducing anxiety, pain and fatigue in transplant patients, and thus improving their quality of life after the intervention.
2. Gather user experience, satisfaction levels and recommendations for improvement of the VRH prototype from patients
Methods
Intervention: An intervention program (VRH) that combines VR and hypnosis to facilitate the patient's absorption into a safe, benevolent imaginary world, in which they will be invited to live an experience that distracts them from their negative emotions and pain (Toujours Dimanche application).
The virtual experience will be structured along the lines of a hypnosis session: 1- A soothing immersion will first be offered to catalyze absorption through gentle descents and calming audio-visual stimuli, 2- Reaching a safe, relaxing space, dreamily representing two soothing natural environments (beach or park of the patient's choice), 3- Two therapeutic stress-management activities (dropping into a bag containing all the stress the participants want to get rid of, and allowing the participants to be carried by an imaginary horse, which enables them to escape to a safe place), 4- a physical discomfort manipulation activity enabling participants to remove the sensation of discomfort from the part of their body afflicted by it, and 5- Return to an awake state of consciousness.
The application allows the patient to visit a pleasant place either by taking control of it or in a guided way accompanied by a hypnosis verbatim. The patient can choose between these two options, and the investigators document how he or she uses the application.
Participants : Sixty participants with hematological cancer undergoing stem transplantation will be included in this research. They will be randomized in the two groups of the study : VRH and control (waiting list, will have the intervention at the end of the study).
Procedures: Participants will be asked to complete self-evaluations at four measurement points: T0=pre intervention (one week after the day of transplantation), T1=first session (one week after the day of transplantation), T2= one month post-transplantation and T3=three months follow-up post-transplantation. Interviews to gather patient expectations and satisfaction levels will also be conducted at T0 and T3 respectively for patients in the VRH condition. The first session takes place after the transplant (about 1 week) and patients then use the application at their own pace. The headset then remains available for use during the following two weeks. With the application, they have access to 4 hypnosis recordings (Beach, Forest, MagicHand and SecurityProtection) as well as a bank of landscapes they can visit. They have the choice of using contemplative VRH (with hypnosis) or active VR (wandering through the landscapes on their own). How they use the application will be documented with a logbook.
Measures :
Quality of life will be documented by the FACT-BMT, a scale validated for patients undergoing bone marrow transplantation. It contains 50 items divided in 5 subscales : Physical Well-Being, Social/Family Well-Being, Emotional Well-Being, Functional Well-Being, Bone Marrow Transplantation Subscale scored on a 5-points Likert scale.
The HADS, a scale validated in French for cancer, will assess participants' anxiety-depression. This scale is made up of 14 items: 7 items determine the degree of anxiety and the other 7, the degree of depression. The score of each subscale is calculated by summing the score of each item, which varies between 0 and 3, so that each subscale can reach a maximum score of 21
Pain will be assessed with the Brief Pain Inventory. This scale is made of 8 items on a 10-points Lickert scale assessing severity of pain, impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week.
Fatigue will be assessed with the Multidimensional Fatigue Inventory 10 items version (MFI-10) adapted for cancer. It is scored on a 5-points Likert Scale going form 1: "do not agree at all" to 5: "totally agree".
Ten-level Visual Numerical Scales (VNS) will also be used to assess pain, anxiety, absorption, i.e., the tendency to become totally involved in a perceptual and imaginative experience, and dissociation, i.e., a mental separation of components of the experience, fatigue and amusement.
The investigators will collect patients' levels of expectation and satisfaction through 5-level VNS (1 = "not at all satisfied", 5 = "very satisfied") and through explanatory interviews.
The Simulator Sickness Questionnaire, a scale validated in French assesses cybersickness symptoms related to VR immersion. It contains 16 items divided in two subsacles: nausea and oculomotor, which the participant must qualify with "not at all" (scored 0) , "a little" (scored 1), "moderately" (scored 2) or "severely" (scored 3).
Analyses : Continuous quantitative variables will be expressed as mean +/- standard deviation, and categorical variables as headcounts and percentages. Statistical analyses will be performed using jamovi 2.3.18 software with a threshold α = 0.05.
Quantitative analysis
After checking for applicability, in order to evaluate the effectiveness of the intervention in the experimental group compared to the control group, a MANOVA will be performed. The dependent variables are anxiodepressive symtoms, pain, quality of life and fatigue, and the independent variables are the different measurement times. The investigators will control for age, gender, socioeconomic status, diagnosis absorption, dissociation, and amusement, . If suitable, the investigators will make post-hoc comparisons to compare scores between groups and at each measurement time with a Bonferroni correction.
Correlations will be performed on variables measured during the transplant phase (anxiety, pain, fatigue, absorption, dissociation, amusement) to measure the immediate effects of VRH. Correlations will be made between pre- and post-intervention scores and will be estimated with Pearson's or Spearman's correlation and their 95 % CI. Correlations will also be made between primary and secondary outcomes.
The investigators expect better effects on primary outcomes, i.e., diminution of anxiety and pain levels and secondary outcomes, i.e., quality of life and fatigue for the VRH program than for condition C.
Qualitative analysis
The verbatims from the semi-structured interviews will be analyzed qualitatively using NVivo software. The software enables thematic content analysis, highlighting codes in the text and graphically grouping them into themes to create a thematic tree. To identify the key themes in patients' explicit discourse, a general inductive method inspired by Braun and Clarke (2021) will be employed, aiming to uncover recurring patterns directly from the data. This data-driven approach involves deriving themes organically from the dataset. The recommended process involves six main steps after preparing the raw data files (e.g., formatting and correcting transcription errors): 1) thoroughly reading the transcripts to become familiar with the data, 2) conducting line-by-line coding to generate initial codes, 3) identifying recurring themes, 4) reviewing and refining these themes, 5) defining and naming each theme, and 6) producing a report that incorporates verbatim examples.
