About this study
This study will be conducted to determine the effects of virtual reality (VR) intervention applied during colonoscopy performed without sedation on pain, anxiety, embarrassment, and physiological parameters.
Read the detailed description
This randomized controlled experimental study will be conducted to determine the effects of virtual reality (VR) intervention on pain, anxiety, embarrassment, and physiological parameters in patients undergoing colonoscopy. The study population will consist of patients with an appointment for colonoscopy at the endoscopy unit of a research and training hospital located in a province of Türkiye.
The sample size was calculated using the independent samples t-test in G*Power 3.1.3 (Franz Faul, Kiel University, Germany). Based on the pain scores measured by the Visual Analog Scale (VAS) reported by Karaveli Çakır et al. (2021) (intervention group = 2.76 ± 1.25; control group = 3.76 ± 2.11), the minimum required sample size was calculated as 76 participants (intervention group = 38; control group = 38), with a one-tailed power of 0.80 (1-β) and a 95% confidence interval (p < 0.05).
Individuals aged 18-65 years who were undergoing colonoscopy without sedation for the first time and who voluntarily agreed to participate will be included in the study. Patients with hearing or visual impairments, communication difficulties, a history of psychiatric disorders, chronic pain complaints, dementia, previous abdominal or pelvic surgery, or use of anxiolytic/analgesic medications within the last 72 hours will be excluded.
Participants will be randomly assigned to two groups using a randomization tool generated via Randomizer (www.randomizer.org). All patients will undergo standard bowel preparation prior to colonoscopy. On the day of the procedure, patients presenting to the unit will be admitted to the waiting area. The purpose of the study will be explained to the participants, and written and verbal informed consent will be obtained.
Before the procedure, vital signs (heart rate, systolic and diastolic blood pressure, respiratory rate, and oxygen saturation) will be measured. Anxiety will be assessed using the Spielberg State-Trait Anxiety Scale (STAI-S, STAI-T), while anxiety and embarrassment will be evaluated using the Visual Analog Scale (VAS). Embarrassment will additionally be assessed using the Colonoscopy Shame Scale.
In the endoscopy room, VR headsets will be placed on all patients in both the intervention and control groups by a researcher who is not the endoscopist. Patients in the intervention group will watch a licensed virtual reality video via an Android smartphone application. These patients will receive full VR therapy before and during the procedure, with the video delivered through VR goggles. Patients in the control group will not watch or listen to any content. This procedure will ensure that the endoscopist remains unaware of whether patients are receiving VR therapy. Due to the nature of the intervention, blinding of participants and outcome assessors was not feasible; however, the endoscopist and data analysts will be blinded to group allocation.
For the colonoscopy procedure, patients will be positioned in the left lateral position, and local anesthetic gel and lubricant (Vaseline) will be applied to the anal region. No sedation will be administered. Colonoscopy will be performed using a flexible colonoscope with carbon dioxide (CO₂) insufflation. Patients will be continuously monitored during the procedure, and vital signs will be recorded. Additionally, oxygen will be administered via nasal cannula at a rate of 4 L/min. Conscious sedation equipment will be readily available for patients who are unable to tolerate colonoscopy without sedation. Cecal intubation will be achieved in all patients. The start and end times of each colonoscopy procedure will be recorded.
After completion of the procedure, patients will be transferred to the recovery unit. Vital signs will be reassessed, and pain, anxiety, and embarrassment experienced during the procedure will be evaluated using the Visual Analog Scale (VAS). The State Anxiety subscale of the Spielberg State-Trait Anxiety Scale will also be administered.
After coding and data entry, statistical analyses will be performed using IBM® SPSS® Statistics 30. Differences between groups in terms of demographic variables will be analyzed using the Chi-square test or Mann-Whitney U test, as appropriate. Independent samples t-test will be used for pairwise comparisons. A linear regression model will be applied to evaluate the relationships between various risk factors and anxiety levels. Repeated measures analysis of variance (ANOVA) will be conducted to compare changes in outcomes over time. Statistical significance will be set at p < 0.05.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Virtual Reality (VR) Intervention GroupDevice
The intervention consists of a virtual reality (VR) application delivered via a head-mounted display integrated with an Android-based smartphone. Participants assigned to the intervention group will view immersive audiovisual content beginning prior to the colonoscopy procedure and continuing throughout the procedure. The VR application is designed to provide distraction and reduce procedural pain, anxiety, and embarrassment. No sedation will be administered. Standard monitoring and colonoscopy procedures will be conducted in accordance with institutional protocols.
| Study group | Role | What they receive |
|---|---|---|
| Virtual Reality (VR) Intervention Group | Experimental | Participants assigned to this arm will receive a licensed virtual reality (VR) application delivered via a head-mounted display before and during colonoscopy. The VR content will be presented through an Android-based smartphone integrated into the VR headset. Participants will not receive sedation. Standard colonoscopy procedures and monitoring will be performed in accordance with institutional protocols. Receives: Device: Virtual Reality (VR) Intervention Group |
| No Intervention | No intervention | Participants assigned to this arm will receive standard care during colonoscopy without any virtual reality or audiovisual distraction intervention.

- This study is designed as a prospective, randomized, parallel-group, controlled interventional trial with a 1:1 allocation ratio. Eligible participants will be randomly assigned to either the virtual reality (VR) intervention group or the control group. Participants in the intervention group will receive a licensed VR application delivered via head-mounted display before and during colonoscopy, whereas participants in the control group will receive standard care without any audiovisual distraction. Due to the nature of the intervention, participant and outcome assessor blinding is not feasible. However, the endoscopist performing the procedure and the data analysts will be blinded to group allocation to minimize potential bias. The primary outcomes include pain intensity, anxiety level, and embarrassment experienced during colonoscopy. Secondary outcomes include physiological parameters (heart rate, blood pressure, respiratory rate, and oxygen saturation) and procedure duration.
