Respiratory sinus arrhythmia moderates the interpersonal consequences of brooding rumination.

Area of Science:

• Psychology
• Psychophysiology
• Social Psychology

Background:

• Brooding rumination, a maladaptive emotion regulation strategy, is linked to adverse interpersonal outcomes.
• Respiratory sinus arrhythmia (RSA), a measure of self-regulatory capacity, may mitigate these negative effects.

Purpose of the Study:

• To investigate the moderating role of RSA in the relationship between brooding rumination and negative interpersonal consequences.
• To examine how RSA influences social interactions and support perception in the context of rumination.

Main Methods:

• Three studies with convenience samples (total N = 420) were conducted.
• RSA was measured as a psychophysiological marker.
• Interpersonal behaviors, social support, interpersonal stress, and depressive symptoms were assessed.

Main Results:

• Lower RSA was associated with a stronger link between brooding rumination and negative interpersonal behaviors.
• Individuals with lower RSA reported less perceived instrumental social support.
• Brooding rumination indirectly predicted depressive symptoms through increased daily interpersonal stress, especially for those with lower RSA.

Conclusions:

• RSA may buffer the negative interpersonal consequences of brooding rumination.
• Interpersonal difficulties are exacerbated by brooding in individuals with lower self-regulatory capacity (RSA).
• Findings underscore the importance of RSA in understanding the social impact of maladaptive emotion regulation.
