Interpersonal versus intrapersonal emotion regulation: Intensity of negative emotion predicts usage probability

Emotional intensity seems to be related to the selection of emotion regulation (ER) strategies. Previous studies have focused primarily on intrapersonal ER. In contrast, everyday use of interpersonal ER remains understudied, with the association between perceived emotional intensity and selection of intra- or intrinsic interpersonal ER still unclear. In a preregistered study, we used experience sampling method data from a community sample of individuals in a heterosexual relationship (n = 183) who provided reports on their daily lives over a period of 4 weeks during the first COVID-19 lockdown in 2020. Surveys included questions about various emotions, their perceived intensity, and selected ER strategies. Results revealed more frequent use of ER overall with increasing emotional intensity of all negative emotions (except for boredom). In line with our hypothesis, results showed that greater emotional intensity increased the probability of interpersonal ER more strongly than intrapersonal ER for most negative emotions, in both women and men. Additionally, we found that men used significantly more intrapersonal than interpersonal strategies at average emotional intensity of all negative emotions. A preference for interpersonal ER in the face of highly intense emotions may be related to a higher demand for resources, which is compensated through social connection. In the association between perceived emotional intensity and ER selection, our research highlights the importance of considering both intra- and interpersonal ER strategies.
