Background
Higher levels of social media use (SMU) have demonstrated associations with higher levels of self-reported stress. However, the association between SMU and physiological markers of stress, such as heart rate variability (HRV), is less understood. We hypothesize that increased time spent each day on social media will be associated with decreased baseline HRV, but only for individuals who report high rates of stress. We also hypothesize that time spent on social media will be associated with decreased baseline HRV for individuals with higher levels of neuroticism. When considered together, we hypothesize the largest association between SMU and baseline HRV for individuals with higher levels of both stress and neuroticism.
Methods
Using a sample of 165 undergraduate students, we measured baseline heart rate variability with a 3-lead ECG. We determined the average SMU using the Social Media Use Questionnaire (SMUQ). We also ascertained self-reported stress levels using the Depression, Anxiety, and Stress Scale (DASS), and levels of neuroticism using the IPIP NEO Neuroticism Extraversion Openness - PR (IPIP-NEO-120). We will use multivariate regression for our analysis.
Results
Results are undergoing analysis.
Conclusions
While the use of social media by itself may not have a clear direct association with HRV, it is important to consider the effects of social media use on people with a high emotional state of stress and/or high levels of neuroticism. As public policy continues to be developed for social media, it is important to consider how people with higher tendencies to become stressed and those with higher levels of neuroticism can be affected by social media use if unregulated.
