These theories also help to promote the central themes and strategies of positive psychology. The Triangular Love Theory ( Robert Sternberg, 1988) features love organized in 3 categories. These categories are passion, intimacy, and commitment. These are the 3 major components of love. Passion reflects attraction, romance and sexual desire. Intimacy is the feeling of closeness, trust and innermost thoughts. Commitment is the decision to maintain a long term caring relationship. Sternberg's Triangular Love Theory scale provides insight into the nature of relationships.
Hatfield's 2 Factor Theory is another that interprets physiological arousal that happens in a romantic situation such as passion. The Model Michelangelo says our close relationships powerfully shape our well-being.
Another theory is the minding theory. The minding theory states that certain types of perceptions and expectations are key to satisfying close relationships. Both people or partners must be committed to pursuing knowledge, acceptance and positive attributions for the relationship to survive. Both partners must continue to find out about one another, respect each others individuality and engage in positive attributions.
