Abstract
Predictions derived from Sternberg's (1986) Triangular Theory of Love were tested. Two-hundred- and-four adults completed questionnaires assessing several constructs, including each of the three components of the theory: intimacy, passion and commitment. Results indicated mixed support for the Triangular Theory. As expected, self-reported levels of commitment were higher for the respondents in more serious (i.e. married vs unmarried) relationships. The predicted decline over time in passion emerged only for females, and intimacy levels did not generally display the predicted decline for longer relationships. Commitment was the most powerful and consistent predictor of relationship satisfaction, especially for the longest relationships. Other results indicated a need for more psychometrically sound measures of these constructs, and the desirability of using adult, non-student samples for investigations of romantic love.
