Snippet: Despite the unfolding impact of the COVIDâ€19 pandemic on psychological wellâ€being, there is a lack of prospective studies that target physiological markers of distress. There is a need to examine physiological predictors from the preâ€pandemic period to identify and treat individuals atâ€risk.

Document: Despite the unfolding impact of the COVIDâ€19 pandemic on psychological wellâ€being, there is a lack of prospective studies that target physiological markers of distress. There is a need to examine physiological predictors from the preâ€pandemic period to identify and treat individuals atâ€risk. In this study, our aim was to use preâ€pandemic markers of autonomic nervous system (ANS) parasympathetic and sympathetic regulation to predict individuals' psychological wellâ€being during the crisis. We also assessed the role of mood regulation expectancies as a mediator of the association between preâ€pandemic physiological measures and COVIDâ€related wellâ€being. In May to June 2020, 185 Israeli adults completed online questionnaires assessing their mood regulation expectancies since COVIDâ€19 began, and their current wellâ€being. These individuals had participated in lab studies 1.5–3 years prior to this assessment, where their physiological measures were taken, including respiratory sinus arrhythmia (RSA) and skin conductance level (SCL). RSA was positively related to mood regulation expectancies during COVIDâ€19 (b = 3.46, 95% CI [0.84, 6.05]). Mood regulation expectancies, in turn, positively predicted wellâ€being during the crisis (b = 0.021, 95% CI [0.016, 0.027]). The mediation was significant and moderated by SCL (index = −0.09, 95% CI [−0.02, −0.0001]), such that it was strongest for individuals with low SCL. We point to preâ€pandemic physiological mechanisms underlying individuals' mental wellâ€being during the COVIDâ€19 pandemic. These findings have theoretical, diagnostic, and clinical implications that may refine our understanding of the physiological basis of resilience to the COVIDâ€19 pandemic and thus may be implemented to identify and assist individuals in these times.
