This study identifies concepts associated with positive valence of romantic relationship and partner, in order to characterize the schemas about these two phenomena. Participants (N = 158, 134 women) were asked to write about the positive aspects of their relationship and their partner. These reports were subjected to lexical and content analysis. Nineteen categories emerged, related to the concepts that compose the relationship schema, and 21 others related to the partner. Words and categories most frequently mentioned to characterize positive aspects of the relationship were companionship and trust, and to characterize positive aspects of the partner were caring and affectionate. There was recurrence in words and categories used among participants, indicating consensus about which aspects are positive in a relationship and a romantic partner. Differences in relationship satisfaction levels between those who mentioned and those who did not mention categories created from the reports were tested. Individuals who mentioned categories as companionship, affection, respect, and dialogue showed higher levels of satisfaction than those who did not mention these categories. The results suggest that the schemes can provide indicators of satisfaction with the relationship.
