Self-presentation represents behaviors used in establishing an identity with others; such behaviors may differ across various interpersonal relationships. The current article presents two studies examining differences in self-presentation to acquaintances, friends, and romantic partners among college students in relationships. Study 1 was an experiment, and Study 2 utilized a within-subject design. Results showed that individuals engaged in more self-presentation in more established types of relationships. Additionally, both closeness and trust served as moderators, such that those lower in closeness/trust reported more self-presentation in more established types of relationships than in less established types of relationships. At higher levels of closeness/trust, the results were somewhat inconsistent, with Study 1 finding no differences between relationship types and Study 2 finding more self-presentation to romantic partners than to friends and acquaintances. These results are among the first to suggest that individuals engage in differing levels of self-presentation, depending on the type of relationship and the extent to which they feel close to and trust the person.
