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
Blinded (masking used)
