The purposes of the study were (1) to identify if relational benefits had positive influences on relationship quality (satisfaction and commitment), (2) to examine if there were significant differences of relational benefits and relationship quality in terms of relationship frequency and relationship duration, and (3) to investigate interaction effects of relationship frequency on the relationships between relationship duration and relational benefits/relationship quality. The results showed that satisfaction was positively influenced by relational benefits, while commitment was affected by all types of relational benefits. In addition, there were significant differences of relational benefits and relationship qualities in terms of relationship frequency. However, there were no significant differences of relationship benefits and relationship qualities in terms of relationship duration. Additionally, there were no interaction effects of relationship frequency and relationship duration to evaluate relationship qualities. Managerial implications were discussed.
