Music and ABS as a Potential Anxiety Intervention

Anxiety State Clinical Trial

Official title: Music and Auditory Beat Stimulation and Its Effect on Anxiety

Status Not yet recruiting

Clinical Trial Summary

Anxiety is a growing problem and has been steadily increasing, particularly in the adolescent and young adult populations in the past 24 years. Music and auditory beat stimulation (ABS) in the theta frequency range (4-7 Hz) are sound-based anxiety treatments that have been investigated in prior studies with subjective measures of anxiety. Here, the anxiety-reducing potential of calm music combined with theta ABS will be examined in a large sample of participants with objective psychophysiological measures (heart rate variability and EEG), stress hormone measures (salivary cortisol) along with subjective measures (STICSA state). Participants with moderate trait anxiety (n = 100) will be randomly assigned to a single 24-minute session of sound-based treatment: combined (music & ABS), or pink noise (control). Pre- and post-intervention heart rate variability and EEG band power (alpha, beta, delta, and theta bands), along with somatic and cognitive state anxiety measures (STICSA State) will be collected along with trait anxiety (STICSA Trait), and musical preferences (Short Test of Music Preferences). Our hypothesis is that the music & ABS condition will have significantly higher EEG theta band activity and heart rate variability compared to the pink noise control condition. The investigators also expect to see significantly reduces higher state anxiety reduction in the music & ABS condition compared to the pink noise control condition. Participants with moderate trait anxiety (n = 100) will be randomly assigned to a single 24-minute session of sound-based treatment: combined (music & ABS), or pink noise (control). Pre- and post-intervention heart rate variability and EEG band power (alpha, beta, delta, and theta bands), along with somatic and cognitive state anxiety measures (STICSA State) will be collected along with trait anxiety (STICSA Trait), and musical preferences (Short Test of Music Preferences). The investigators predict that the music & ABS condition will have significantly increased power in the theta and alpha bands, higher heart rate variability, higher state anxiety reduction, and lower salivary cortisol levels compared to the pink noise control condition.

Clinical Trial Description

In this study, the investigators will examine and compare the effectiveness of a combination of music and theta auditory beat stimulation (ABS) (as measured by the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA)) compared to a control condition (pink noise). Prior work has demonstrated that ABS and music both reduce anxiety when presented on their own. It is hypothesized that music with ABS will lead to significantly lower anxiety levels and increased calmness compared to the pink noise control condition. Approximately 100 participants with moderate trait anxiety will be recruited from the greater Toronto area. The study will be conducted in the SMART lab at Toronto Metropolitan University and the experimental treatment will be provided with the LUCID Research App. Upon arrival in the lab research staff will go over experimental expectations, and participants will be asked to fill out the Short Test of Music Preferences (STOMP), the Positive and Negative Affect Scale (PANAS), and Self-Assessment Manikin (SAM), and the STICSA trait and state. They will also be asked to "please list any medications you are taking, including marijuana and/or CBD". A baseline salivary cortisol sample will be taken from participants. Participants will then undergo EEG administration, assessment of spontaneous blink rate, and HRV, first obtaining a baseline level of these measures. EEG (alpha, beta, delta, and theta bands) will be recorded using the BioSemi EEG system via 64 scalp electrode sites according to the international 10-20 electrode system as done in a previous study examining EEG response to meditation. Linked mastoids will serve as a reference. Horizontal eye movements will be recorded using two electrodes placed 1 cm lateral to the outer canthi of each eye. Vertical eye movement potentials will be recorded using two electrodes placed in the center of the supraorbital and infraorbital regions of the left eye. These will be used to obtain the spontaneous blink rate of participants which is an analog of the sensitivity and responsiveness of the mesostriatal dopaminergic system that has in previous studies determined the degree to which gamma binaural beats affect cognition. Heart rate variability will also be recorded via the BioSemi system with two flat active electrodes attached to the participant's left and right wrists. Participants will then listen to their randomly assigned intervention for 24 minutes (music with theta ABS or pink noise). A post-intervention salivary cortisol sample will be taken along with a post-intervention EEG and HRV reading and the completion of the STICSA state anxiety questionnaire. An additional salivary cortisol sample will be taken 15 minutes after the end of the auditory treatment. If there are no significant pre-post differences in salivary cortisol levels between the treatment groups after collecting data from 50 participants, the investigators will cease collecting salivary cortisol. The investigators predict that the music & ABS condition will have significantly increased power in the theta and alpha bands compared to the pink noise control condition. The investigators also predict that the music & ABS condition will have higher heart rate variability compared to the pink noise control condition. The investigators also expect to see significantly higher state anxiety reduction and significantly lower salivary cortisol levels in the music & ABS condition compared to the pink noise control condition. ;
