When holding back helps: suppressing negative emotions during sacrifice feels authentic and is beneficial for highly interdependent people.

Is the suppression of negative emotions ever associated with beneficial outcomes in relationships? The study reported here drew on research and theory on emotion regulation, self-construal, and sacrifice to test the hypothesis that individual differences in interdependent self-construal moderate the association between negative-emotion suppression and the personal and interpersonal outcomes of sacrifice. In a 14-day daily-experience study of people in romantic relationships, people with higher levels of interdependence experienced boosts in personal well-being and relationship quality if they suppressed their negative emotions during sacrifice, whereas those who construed the self in less interdependent terms experienced lower well-being and relationship quality if they suppressed their negative emotions during sacrifice. Feelings of authenticity for the sacrifice mediated these associations. These findings identify a critical condition under which the suppression of negative emotions may be personally and interpersonally beneficial.
