Background: Due to the increasing prevalence of intestinal diseases, colonoscopy is considered a safe and fast diagnostic and treatment method for these patients. According to studies, most patients waiting for a colonoscopy experience fear and anxiety. This study aimed to investigate the effect of a pre‑colonoscopy education program on the fear and anxiety of patients undergoing colonoscopy.

Materials and Methods: This randomized clinical trial study was conducted on patients undergoing colonoscopy in hospitals in southeast Iran. A total of 90 participants were selected by convenient sampling and randomly assigned to two groups control (n = 45) and intervention (n = 45). The patients in the intervention group received nursing interventions before colonoscopy, while the patients in the control group received only routine care. The data were collected using a researcher‑made fear of colonoscopy scale, its Cronbach’s alpha coefficient (0.92), and the Spielberger State‑Trait Anxiety Inventory. The data were analyzed with a Chi‑square t‑test and pair t‑test.

Results: The data showed that anxiety and fear of colonoscopy in the patients in the intervention group significantly decreased compared to the patients in the control group (p <0.001).

Conclusions: Using non‑pharmacological methods before colonoscopy can reduce the fear and anxiety in patients who are candidates for this procedure and similar invasive procedures. The intervention performed in this study can be used together with other methods to control patients’ fear and anxiety. Especially for nurses, It is recommended to do pre‑colonoscopy education programs for these clients.
