We contend that closerelationships provide adults with optimal opportunities for personal growth when relationshippartners provide accurate, honest feedback. Accordingly, it was predicted that young adultswould experience the relationship quality with relationship partners who evaluated them in amanner consistent their own self-evaluations. Three empirical tests of this self-verificationhypothesis as applied to close dyads were conducted. In Study 1, young adults in datingrelationships were most intimate with and somewhat more committed to partners when theyperceived that partners evaluated them as they evaluated themselves. Self-verification effects werepronounced for those involved in more serious dating relationships. In Study 2, men reported thegreatest esteem for same-sex roommates who evaluated them in a self-verifying manner. Resultsfrom Study 2 were replicated and extended to both male and female roommate dyads in Study 3.Further, self-verification effects were most pronounced for young adults with high emotionalempathy. Results suggest that self-verification theory is useful for understanding dyadicadjustment across a variety of relational contexts in young adulthood. Implications ofself-verification processes for adult personal development are outlined within an identitynegotiation framework.
