Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention involved showing the preoperative patient in the preoperative ward a 6 minute video which provides information about the anesthetic procedure that they will receive. The video was shown to the patient around 1 - 2 hours prior to the induction of anesthetic. The video incorporated techniques known to illicit an Autonomous Sensory Meridian Response (ASMR). The patients' anxiety was assessed before and after the intervention.

ASMR is an alternative approach to relaxation and is currently very popular. The technique itself involves incorporating visual and acoustic stimuli delivered via video to elicit a low-grade euphoric response.

Comparator / control treatment
The control involved having the patient watch a video providing information about the anesthetic procedure that they were going to receive. The content of the video is the same as the intervention video but was delivered normally without any ASMR elements.
Control group
Placebo

Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocations were concealed. The sequence was generated beforehand using a random number generator. The intervention video and the control video was named by a third party so that the assessor did not know the allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was done using computer software.
Masking / blinding

Summary
Brief summary
The purpose of this study is to test whether a video designed to trigger the Autonomous Sensory Meridian Response (ASMR) will have an effect on preoperative anxiety. Preoperative anxiety is a significant phenomenon that negatively impacts patients that are preparing to undergo a procedure.

In this study, we showed preoperative patients an informational video that told them about the anesthetic procedure that they were going to undergo. This video was either one specially designed to trigger an ASMR, or a normal video with the same information. ASMR is an alternative approach to relaxation and is currently very popular. You-Tube channels dedicated to producing ASMR videos have large followings and achieves significant viewership. Despite its rising popularity in society, only a few studies have been conducted to scientifically evaluate the effects of ASMR.

We measured preoperative anxiety using standardized questionnaires that have been proven to be effective in many other studies. The questionnaires that we chose are the Visual Analogue Scale (VAS), the State-Trait Anxiety Inventory (STAI) and the Amsterdam Preoperative Anxiety and Information Scale (APAIS). We compared the results from the patients that watched the ASMR video with the results from patients that watched a normal video.

Our aim is to assess the effects of ASMR on preoperative anxiety and determine if it yielded any clinically significant effects.
