Objectives: Coronary angiography can be stressful for patients and anxiety-caused physiological responses during the procedure increase the risk of dysrhythmia, coronary artery spasms and rupture. This study therefore aimed to investigate the effects of peer, video and combined peer-and-video training on anxiety among patients undergoing coronary angiography. Methods: This single-blinded randomised controlled clinical trial was conducted at two large educational hospitals in Iran between April and July 2016. A total of 120 adult patients undergoing coronary angiography were recruited. Using a block randomisation method, participants were assigned to one of four groups, with those in the control group receiving no training and those in the three intervention groups receiving either peer-facilitated training, video-based training or a combination of both. A Persian-language validated version of the State-Trait Anxiety Inventory was used to measure pre- and post-intervention anxiety. Results: There were no statistically significant differences in mean pre-intervention anxiety scores between the four groups (F = 0.31; P = 0.81). In contrast, there was a significant reduction in post-intervention anxiety among all three intervention groups compared to the control group (F = 27.71; P <0.01); however, there was no significant difference in anxiety level in terms of the type of intervention used. Conclusion: Peer, video and combined peer-and-video education were equally effective in reducing angiography-related patient anxiety. Such techniques are recommended to reduce anxiety amongst patients undergoing coronary angiography in hospitals in Iran.
