Relationships- Rusbult’s Investment Model (Theories Of Romantic RS) Flashcards
Investment theory:
Developing SET. When deciding on continuing a relationship, more has to be considered than just the current level of satisfaction. Potential alternative relationships and how much has already been invested are also important.
Commitment = Satisfaction - Alternatives + Investment
Investment Size:
What distinguishes investments from rewards/costs is once invested into a relationship, they cannot be easily recovered in a break up or may be difficult to divide.
Categories of investment:
Intrinsic and extrinsic
intrinsic:
these are resources put directly into the relationship, emotional work, time spent and self disclosures.
Extrinsic:
resources that used to be outside of a relationship but become strongly connected to the relationship. Such as shared friendships, memories, material possessions, activities/events that become associated, children
Investments:
Can be rewarding or costly, such as shared friendships would be rewarding and investments in money would be costly.
Commitment:
is increased by the amount of investment as the person feels locked into the connection, ending the relationship would mean sacrificing the resources.
Investment model is an ____ theory
Economic theory
Investment model of relationships
Rusbult (1983)
• Suggests that
the maintenance of a relationship is determined by commitment
• In this context commitment refers to the likelihood that the relationship will persist.
• Commitment can be strengthened by:
- Satisfaction
- Investment
• Commitment is weakened by:
- Presence of alternatives to the relationship
Satisfaction=
Comparison level
Satisfaction=
Comparison level
Quality of alternatives
• Attractive alternative = they may leave the relationship.
• No alternative exists = they may maintain the relationship.(Increases satisfaction)
However, sometimes having no relationship is a more attractive alternative than being in an unsatisfactory one.
Supporting research evidence
Benjamin Le and Christopher Agnew
Some of the strongest support for the investment model comes from a meta-analysis by Benjamin Le and Christopher Agnew (2003).
They reviewed 52 studies from the late 1970s to 1999, studies which together included some 11,000 participants from five countries. They found that satisfaction, comparison with alternatives and investment size all predicted relationship commitment. Relationships in which commitment was greatest were the most stable and lasted longest.
An especially supportive finding was that these outcomes were true for both men and women, across all cultures in the analysis, and for homosexual as well as heterosexual couples.
This suggests there is some validity to Rusbult’s claim that these factors are universally important features of romantic relationships.
