Background: Endoscopy is a diagnostic tool, which causes its candidates different levels of anxiety. Anxiety can reduce patients' tolerance and cooperation and increase the likelihood of endoscopy-related complications. One strategy to alleviate anxiety is patient education. However, previous studies reported conflicting findings about the most appropriate patient education method. Objectives: This study aimed at examining the effects of video-and pamphlet-based patient educations on anxiety and satisfaction among candidates for gastroscopy. Methods: This quasi-experimental study was conducted on 90 patients referred to the endoscopy unit of Valiasr hospital in Birjand city, Iran. The patients were selected through convenience sampling method and randomly allocated to a video, pamphlet, or control group. Data were collected using a demographic questionnaire, a researcher-made questionnaire for satisfaction assessment, and the Spielberger's state-trait anxiety inventory. One day before gastroscopy, the participants completed the demographic questionnaire and Spielberger's state-trait anxiety inventory. Then, educations were provided to them. In the day of their gastroscopy, their anxiety was reassessed both two to three hours before and immediately after the procedure. Collected data were entered into the SPSS software version 15. As all study variables had normal distribution, the data were analyzed by performing the one-way analysis of variance, the Tukey's post hoc, the paired-and independent-sample t test, the chi-square, and Fisher's exact tests at a significance level of less than 0.05. Results: The groups did not differ significantly from each other regarding the pretest and posttest values of total, state, and trait anxiety. However, the level of patient satisfaction in the video group was significantly greater than the control and pamphlet groups (P < 0.05). Moreover, patient satisfaction was not significantly correlated with patients' demographic characteristics. Conclusions: Video-based patient education can improve patient satisfaction among candidates for gastroscopy.
