Objective: Colonoscopy is a complex procedure whose optimal outcome depends largely on the patient's active cooperation. This study sought to evaluate whether providing an informative video could reduce anxiety levels in patients awaiting colonoscopy. Material and Methods:This prospective randomized controlled trial assigned participants to two groups by sequential randomization. One group received standard verbal and written explanations before the colonoscopy, while the other group received an additional video-based educational intervention. Demographic characteristics, satisfaction scores, and State-Trait Anxiety Inventory- State (STAI-S) and State-Trait Anxiety Inventory-Trait (STAI-T) anxiety scores were compared between groups. Results: A total of 347 patients were assessed prospectively. Following the application of exclusion criteria, the final study population consisted of 300 individuals. Participants were equally distributed, with 150 allocated to the video group and 150 to the control group. The two groups had comparable STAI-T scores; the difference was not statistically significant. In the video group, the mean STAI-S score decreased from 42.3+/-8.3 pre-intervention to 39.1+/-8.2 post-intervention, indicating a statistically significant reduction (p<0.001). Conversely, in the control group, STAI-S scores remained essentially unchanged (41.1+/-10.1 vs. 41.2+/-9.6; p=0.581). Post-procedural satisfaction levels were significantly higher in the video group than in the control group (4.3+/-0.8 vs. 2.8+/-1.0, p<0.001). Conclusion: Providing video-animated information, in addition to written and verbal information, before colonoscopy reduces patients' preoperative anxiety. Furthermore, incorporating video-based education leads to improved patient satisfaction with the procedure.
