Respiratory sinus arrhythmia moderates the interpersonal consequences of brooding rumination.

Brooding rumination is an intrapersonal emotion regulation strategy associated with negative interpersonal consequences. Resting respiratory sinus arrhythmia (RSA), a psychophysiological marker of self-regulatory capacity, may buffer the association between maladaptive emotion regulation and negative interpersonal behaviors. The current work examines the moderating effect of RSA on the association between brooding rumination and different negative interpersonal consequences.

Group-based trajectories and predictors of adherence to physical distancing during the COVID-19 pandemic.

: This study sought to identify psychosocial predictors of trajectories of adherence to physical distancing alongside changes in public health measures during the COVID-19 pandemic. : A three-time point longitudinal survey during the first two waves of the COVID-19 pandemic. : Participants ( = 1003) completed self-report measures of adherence to physical distancing over an 8-month period at the start (T1) and end (T2) of the first wave of the pandemic, and the start of the second wave of the pandemic (T3).

Heart rate variability moderates the between- and within-person associations between daily stress and negative affect.

Stress exposure increases risk for depressive symptoms. However, there are substantial individual differences in affective responses to stress. High-frequency heart rate variability (HF-HRV), a marker of vagally-mediated parasympathetic activity, has been conceptualized as a psychophysiological index of emotion regulation that may moderate individuals' responses to stress.

Socio-demographic, social, cognitive, and emotional correlates of adherence to physical distancing during the COVID-19 pandemic: a cross-sectional study.

Objectives: In order for physical distancing directives to be effective at lowering and flattening the epidemic peak during a pandemic, individuals must adhere to confinement guidelines. Recent reviews highlight the paucity of research on empirical correlates of adherence to physical distancing and quarantine directives.

Methods: In this cross-sectional study, 1003 individuals were recruited using quota sampling to form a sample approximately representative of the population of Quebec (Canada) in terms of age, gender, and urbanicity.

Implicit Affect, Heart Rate Variability, and the Metabolic Syndrome.

Objective: Greater negative affect has been associated with an increased risk of the metabolic syndrome (METs). However, all studies to date have examined this association using explicit affect measures based on subjective ratings of emotional experiences. Prior studies suggest that implicit affect, representing the automatic, prereflective appraisal process involved in conscious emotional experiences, is associated with physiological stress responses independent of explicit affect.

Attachment style and changes in systemic inflammation following migration to a new country among international students.

Attachment style may influence the acculturation process by shaping the types of social relationships that individuals form and maintain. Social relationship quantity and quality have been linked to chronic low-grade systemic inflammation, an immune process associated with risk for age-related diseases. The goal of this study was to investigate whether attachment style moderates the change in systemic inflammation during the early phases of the acculturation process, a period associated with rapid changes in social functioning.

High-Frequency Heart Rate Variability Reactivity and Trait Worry Interact to Predict the Development of Sleep Disturbances in Response to a Naturalistic Stressor.

Background: High-frequency heart rate variability (HF-HRV) reactivity was proposed as a vulnerability factor for stress-induced sleep disturbances. Its effect may be amplified among individuals with high trait worry or sleep reactivity.

Purpose: This study evaluated whether HF-HRV reactivity to a worry induction, sleep reactivity, and trait worry predict increases in sleep disturbances in response to academic stress, a naturalistic stressor.
