\begin{abstract}
High frequency heart rate variability (HRV) is a vagally-mediated
physiological index reflecting parasympathetic activity that has been
linked to emotion regulation capacity. However, very limited research
has examined associations of physiological indices of regulation such as
HRV with emotional functioning in daily life. The few studies that exist
have small samples sizes and typically focus on only a narrow aspect of
emotion regulation or emotional functioning. In this study, we examined
associations between HRV assessed in the laboratory and emotional/mental
health functioning in daily life using a 7-day ecological momentary
assessment design in 303 adult community participants. We hypothesized
that higher resting HRV would be associated with higher positive affect,
lower negative affect, less affective variability, greater wellbeing,
fewer depressive and idiographic {[}person-specific{]} symptoms, greater
use of engagement emotion regulation strategies, and less use of
avoidance emotion regulation strategies, as assessed in daily life.
Results revealed that higher resting HRV in the laboratory was
significantly associated with lower negative affect and less frequent
use of avoidance emotion regulation strategies in daily life, although
only avoidance strategies remained significant when both were included
in the same model. We also observed a trend association, such that
idiographic symptoms in daily life were associated with lower resting
HRV. Theoretical and clinical implications are discussed, including the
association of HRV with negatively-valenced, rather than
positively-valenced, daily life experiences.%
