About this study

Official title: Improving Patient Comfort Without Sedation: The Impact of Verbal Suggestion on Anxiety and Pain During Colonoscopy

Colonoscopy is an important diagnostic and screening procedure for colorectal diseases, but it can cause pain and anxiety, especially when performed without sedation. Verbal suggestion techniques - in which the physician provides calm, positive, and encouraging communication during the procedure - may help reduce these unpleasant experiences.

This randomized controlled study aims to evaluate the effect of verbal suggestion on pain and anxiety levels of patients undergoing unsedated colonoscopy. Sixty adult patients will be randomly assigned to either a verbal suggestion group or a control group. In the verbal suggestion group, the endoscopist will use positive and supportive phrases during the procedure (for example: "You are doing great," "Take a deep breath, we'll get through this easily"). The control group will undergo colonoscopy without any verbal intervention.

Pain will be assessed using a Visual Analog Scale (VAS) and anxiety will be measured with the Beck Anxiety Inventory (BAI) before and after the procedure. Heart rate will also be monitored as an objective indicator of anxiety.

The goal of this study is to determine whether verbal suggestion can improve patient comfort and tolerance during colonoscopy without sedation, potentially providing a low-cost and practical method to enhance patient experience.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Verbal SuggestionBehavioural

    During unsedated colonoscopy, the endoscopist will use positive verbal suggestions aimed at reducing patients' anxiety and perceived pain. The phrases include encouraging and calming statements such as "You are doing well," "Take a deep breath," and "We're almost done." The communication is supportive, consistent, and non-directive throughout the procedure.

Study groups in NCT07228884
Study groupRoleWhat they receive
Verbal Suggestion GroupExperimentalPatients undergoing unsedated colonoscopy will receive positive verbal suggestion from the endoscopist throughout the procedure (e.g., "You are doing great," "Take a deep breath," "It will be over soon.")
Receives: Behavioral: Verbal Suggestion
Control GroupNo interventionPatients undergoing unsedated colonoscopy will receive standard communication without verbal suggestion during the procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in anxiety level before and after colonoscopy

    Anxiety will be assessed using the Beck Anxiety Inventory (BAI). BAI scores will be obtained immediately before the procedure and within 10 minutes after completion of the colonoscopy. Higher scores indicate greater anxiety.

    Measured: Immediately before and within 10 minutes after the procedure

  2. Pain intensity during colonoscopy

    Pain intensity will be assessed using an 11-point Numerical Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst possible pain). Pain scores will be recorded at 5 minutes after the start of the procedure and at 10-minute intervals thereafter during colonoscopy.

    Measured: During colonoscopy

Secondary outcomes (2)
  1. Heart rate during colonoscopy

    Heart rate was recorded immediately before the procedure, at 5 minutes after the start of colonoscopy, and at 10-minute intervals thereafter during the procedure.

    Measured: Before and during colonoscopy

  2. Oxygen saturation (SpO₂) during colonoscopy

    Peripheral oxygen saturation (SpO₂) was recorded immediately before the procedure, at 5 minutes after the start of colonoscopy, and at 10-minute intervals thereafter during the procedure.

    Measured: Before and during colonoscopy

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in anxiety level before and after colonoscopy (time frame: Immediately before and within 10 minutes after the procedure). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2026.
