Comparison of Effect of Two Methods of Face-to-Face Training and Educational Video on Anxiety and Physiological Parameters in Candidate Patients for Colonoscopy: A Quasi-Experimental Study

Abstract

Background & aim: Anxiety before invasive procedures such as colonoscopy is one of the most common psychological problems in patients. Nowadays, providing education using different methods before invasive procedures to control patients' anxiety and pain has received a lot of attention. The aim of this study was to compare the effect of face-to-face training and educational videos on anxiety and physiological parameters of patients undergoing colonoscopy. Methods: In this quasi-experimental study, 105 candidates for colonoscopy referred to Shahid Beheshti Hospital of Hamadan were selected by available sampling method from February 2019 to September 2020 and assigned to two groups of face to face (n=52) and educational videos (n=53). Face-to-face training was performed for 15 minutes the night before the colonoscopy. The training video was broadcast to patients for 15 minutes the night before the colonoscopy. Patients' anxiety before and after training was measured by Spielberger Anxiety Questionnaire. Physiological indices were recorded by physiological index table, 5 minutes before, during and 5 minutes after colonoscopy. Data were analyzedby chi-square tests, Ttest, Paired t-testand analysis of variance with repeated measuresin SPSS 16 software. Results: In both groups of face-to-face training and educational video, the mean score of overt and covert anxiety after the intervention was significantly lower (p<0.001). There was no statistically significant difference between the mean scores of overt and covert anxieties in two groups before the intervention. However, after the intervention the mean score of anxiety in the educational film group was significantly lower than the face-to-face training group (p<0.05). From physiological indicators, only systolic blood pressure was statistically different between two groups at all times of measurement (p<0.05). Conclusion:The results of the study showed that training through educational videos has a greater effect on controlling anxiety in patients undergoing colonoscopy than face-to-face training. Therefore, according to the patient's condition, this method can be used instead of the usual method of face-to-face training to better train and control patients' anxiety.
