Triangular Love: 'Not Much More than G'

The Triangular Theory of Love is one of the seminal theories in romantic relationship research. Initial research into the multivariate structure of the Triangular Theory of Love confirmed a three-factor model: passion, intimacy, and commitment. However, further research questioned whether the instruments available were measuring three factors or a single factor. The previous research has focused on the instrument's inability to properly capture the three factors of triangular love but have not questioned the theory itself. The focus of this study is to extend that question of dimensionality and address whether the Triangular Theory of Love is triangular at all. The primary hypothesis of this study was that there would be little more than general variance within the model, eliminating the predictive ability of the single factors of passion, intimacy, and commitment. Results suggest that while predominately a general factor accounts for the majority of variance, some predictive ability remained within the commitment factor. These findings inform future research, suggesting that affects, cognitions, and motivations related to romantic love are one construct, not multiple.
