Abstract
Psychological need satisfaction is essential for daily human functioning and one of its sources is high quality interactions. Rapport is essential to high quality interactions and may be one way that various relationships types can provide the nutriments of healthy functioning. We hypothesized that when people perceive interactions to be higher in rapport, they will experience greater satisfaction of their needs for autonomy, competence, and relatedness. We also explored whether this would be a basic process that would be altered by the relationship between interactants, testing this with multiple operationalizations. We conducted an event-contingent diary study in which participants (nparticipants = 124) responded to items at baseline, each time they experienced an interaction (ninteraction = 1293), and at two-week follow-up. Supporting hypotheses, rapport in interactions was positively associated with need satisfaction within-persons, between-persons, cross-sectionally, and when examining temporal change. Moreover, rapport tended to predict the satisfaction of one’s needs for competence, autonomy, and relatedness independently. Finally, relationships between interactants did not moderate these associations.
