Close relationship investment model
The investment model of close relationships ( investment model of close relationships ) designates one of Caryl Rusbult (1983) theory developed which assumes that in close relationships represent partnership satisfaction and attachment to the relationship, the key theoretical variables that are based on the exchange theory can be explained (see Rusbult & Arriaga, 1997).
Relationship satisfaction is determined by rewards and costs and the relative degree of these two components compared to a personal expectation. It depends on the subjective cost-benefit balance , which is related to the generalized comparison level. The bondage to the relationship depends on the satisfaction, the quality of the alternative relationships available (including the alternative of being alone) and the investments made. This is why the model has been called the “investment model”.
Quality of alternative relationships means that the expected rewards and costs of possible alternatives are considered. The investments are dependent on both extrinsic contributions (e.g. mutual friends) and intrinsic contributions (e.g. self-opening) and include ideal and material resources . They are characterized by the fact that they are directly conditioned by the existence of the close relationship and that their existence is threatened by the dissolution of the relationship.
