Description of intervention(s) / exposure
In this randomised placebo controlled research study, patients in the preoperative waiting room of the Sydney Adventist Hospital (Wahroonga, NSW) will be asked to volunteer to participate in this study to be conducted by university student investigators who will deliver the intervention. Once consent is obtained, adequate privacy of the participants will be ensured by measures such as drawing the curtains in their waiting bay. Participants will have their vital signs measured; including blood pressure, heart rate and respiratory rate; and their anxiety assessed using the Amsterdam Preoperative Anxiety and Information Scale (APAIS), the State-Trait Anxiety Inventory(STAI), and the Visual Analogue Scale (VAS). Participants will then undergo randomisation into two groups: Group 1 to watch a standardised audio-visual ASMR stimulus; and Group 2 to watch a standardised placebo video which is similar but does not contain ASMR triggers. Each video lasts approximately 5 minutes. The video will be delivered on an electronic device such as a tablet or laptop with headphones. The study will use REDCap (Research Electronic Capture Data) to deliver the video and questionnaires Following this intervention, both groups will have their vital signs measured and their anxiety assessed using the methods described above a second time. Following this, both groups will be asked “Did you experience a tingling sensation or mood change during the intervention?” Responders to ASMR will be identified based on this assessment. The total intervention will take approximately 15 minutes, and adherence to the intervention will be monitored by the investigators present at the time of the intervention.

Efficacy
Statistical methods / analysis
Descriptive statistics will be used to analyse demographic data. A paired T-test will be used to detect changes in vital signs and anxiety scores before and after the intervention. A power of 90% with a confidence level of 95% will be required to detect the desired change in anxiety scores. A linear regression model will be used for the analysis of data with; dependent variable: e.g. post anxiety score, and predictors: treatment group, pre anxiety score, any other confounders (age, sex). The sample size is variable in initial stage, depending on number of responders identified. 100 to be included in measurement of anxiety and vital signs.

Summary
Brief summary
The primary objective of this study is to investigate whether an ASMR intervention produces a measurable difference on pre-operative anxiety and primary vital signs using a randomised placebo controlled research study. Validated tools, the Amsterdam Preoperative Anxiety and Information Scale (APAIS), State-Trait Anxiety Inventory (STAI) questionnaire and Visual Analogue Scale (VAS) will be used to assess the pre-operative anxiety. Measuring the blood pressure and respiratory rate will assess the pre-operative primary vital signs. We hypothesise that for responders to ASMR, the intervention will improve anxiety scores and improve vital signs.
