The influence of personality on interpersonal emotion regulation in the context of psychosocial stress

Interpersonal emotion regulation is common in everyday life and important to various outcomes. However, there is a lack of understanding about the personality profiles of people who are good at regulating others’ emotions. We conducted a dyadic study, pairing 89 ‘regulators’ and ‘targets’, with the targets subjected to a psychosocial stressor in the form of a job interview, and the regulators instructed to manage the targets’ feelings prior to the interview. We did not observe any relationship between the regulators’ personality traits and the strategies that they reported using when trying to manage the targets’ feelings, nor between the regulators’ personalities and the targets’ job interview performance. However, the anxiety levels of the targets who were paired with more extraverted regulators fluctuated less across the multiple measures throughout the study, suggesting more effective interpersonal emotion regulation. Our findings suggest that extraversion may be the most relevant trait in shaping interpersonal emotion regulation, and that the influence of personality on regulatory effectiveness is unlikely to arise due to preferences for using different types of strategies.
