Background: Colonoscopy is an important procedure for diagnosing abnormalities of the large intestine. The quality of the examination depends on patients’ knowledge and pre-procedural practices, particularly among first-time patients who may be unfamiliar with the preparation process.
Objectives: To evaluate the effects of an information program combined with video media on knowledge and pre-procedural practices before first-time colonoscopy among urban patients with changes in bowel habits.
Methods: A quasi-experimental, two-group pretest–posttest design was conducted from July 14, 2025, to February 28, 2026. Participants were first-time colonoscopy patients at the Endoscopy Center, Vajira Hospital, selected by purposive sampling and allocated into a control group and an experimental group, with 30 participants per group. The experimental group received routine nursing care plus an information program supported by developed video media, while the control group received routine nursing care. The instruments consisted of a knowledge assessment and a self-practice assessment questionnaire.
Results: The experimental group had a mean age of 59.50 ± 9.14 years; 56.77% were male, and 43.67% had primary education. The control group had a mean age of 60.48 ± 7.99 years; 40.00% were male, and 33.34% had primary education. At baseline, the experimental group had mean knowledge and pre-colonoscopy self-practice scores of 14.44 ± 1.22 and 1.70 ± 0.26, respectively. Following the intervention, these scores significantly increased to 17.60 ± 1.56 and 2.64 ± 0.21, respectively (p < 0.001), and were higher than those of the control group. No significant differences between pretest and posttest scores were observed in the control group.
Conclusion: The information program combined with video media effectively enhanced knowledge and promoted appropriate pre-procedural practices before first-time colonoscopy. Nurses can apply this program as a guideline for preparing patients before colonoscopy.
