Background: Anxiety reduces the patient's tolerance and cooperation and increases the likelihood of complications during endoscopy. Including anxiety reduction strategies are patient education and guided imagery techniques. Considering the different results of studies on the effectiveness of education before endoscopy, the aim of this study was to compare the effect of video education and guided imagery on patients' anxiety before the endoscopy.

Materials and methods: This single-blinded clinical trial was conducted at endoscopy unit of Vasei Hospital in Sabzevar, Iran. Patients as selected by convenience sampling randomized to three groups of video education, guided imagery and control. The data collection tools were demographic and state-trait anxiety inventory (STAI). Video-education group received a video clip and for the guided imagery group provided a guided imagery audio file. The control group received routine care. In the day of their endoscopy, their anxiety was reassessed both two to three hours before the procedure. Data were analysed using SPSS version 21 and one-way analysis of variance, chi-square test, Fisher exact test, independent and paired t-test. The significance level in the statistical tests was 0.05.

Results: There were statistically significant differences in mean pre- and post-intervention anxiety scores between the three groups (P-value<0.05). However, there was no significant difference in anxiety level in terms of the type of intervention used.

Conclusion: According to the findings of this study, two methods of video education and guided imagery were equally effective in reducing anxiety levels in patients before endoscopy.
