Background
Ample empirical evidence indicates that having less and lower-quality social relationships is associated with poorer health outcomes and higher risk for earlier death while having a greater number of positive relationships is associated with more positive physical health outcomes and higher overall odds of surviving (De Vogli et al., 2007; Snyder-Mackler et al., 2020). Meta-analytic studies have indicated that social support is a powerful protective factor against mortality. The importance of social support and social integration is comparable to or exceeds the importance of many established behavioral health risk factors: smoking, excessive alcohol consumption, lack of physical activity, obesity, air pollution, etc. (Holt-Lunstad et al., 2010, 2015). Social connection has also been studied as a buffer for stress (Cohen & Wills, 1985; Gore, 1981; Pearlin, 1989). Those who have better social relationships tend to have higher heart rate variability (HRV) (Donoho et al., 2015; Gouin et al., 2015; Seeman et al., 2014). Studies have found that slow vibroacoustic stimulation tends to increase HRV (Lehrer & Gevirtz, 2014).
Aims
We will be investigating whether wearable vibroacoustic stimulation devices shown to increase vagal tone (HRV) can have a significant impact on the subjective experience of loneliness measured by established loneliness scales.
Method
Research design
RCT. Independent variable: device use. Dependent variables: HRV, Loneliness scores (UCLA Loneliness Scale).
8 groups with 8 devices: 64 experimental participants.
Research participants
Participants: undergraduate students; would get placebo devices, randomly.
Interventions
Participants will wear devices for 2 weeks with vibroacoustic stimulation at random intervals during the duration of the measurement.
Sample size
Based on power analysis of point biserial model correlation t-test for an effect size of 0.3 with alpha levels at 0.05 and power of 0.80 sample size would need to be 64 participants with critical t of 1.66.
Results
Data not collected, completed by May 2023.
Conclusion
Data not collected, completed by May 2023.
