This study investigated the behaviors couples use to indicate their commitment in romantic relationships and explored the complex ways in which these behaviors are interconnected. Survey data were collected from 121 romantically involved couples in the United States. Dyadic analysis of the data revealed that the greater the levels of commitment, the more frequent the use of certain behaviors to indicate commitment. In addition, couples were similar in their use of the indicators, tended to project their self-perceptions onto their partners, and had a degree of accuracy in perceiving their partners’ use of indicators. The research sheds light on some of the complex ways intimate couples experience and express commitment in the everyday lives.
