Rusbult’s Investment Model
Understanding Relationship Endurance Through Roosevelt's Investment Model
Key Influences on Long-Term Commitment
- Roosevelt's investment model identifies three main influences that shape long-term commitment in relationships: satisfaction, quality of alternatives, and the size of investments made by partners.
Satisfaction in Relationships
- Satisfaction refers to the overall balance of positive and negative experiences within a relationship. A partner feels satisfied when their emotional, practical, and sexual needs are met.
Quality of Alternatives
- Alternatives do not solely refer to other potential partners; being single can also be perceived as an appealing alternative. If individuals view these alternatives as more rewarding than their current relationship, their commitment tends to decrease.
Importance of Investments
- Investments encompass time spent together, emotional energy, shared possessions, intertwined friendships, and children. The greater the investment in a relationship, the stronger the psychological tie to it becomes.
Commitment Level Dynamics
- Commitment reflects a person's desire to remain in a relationship. High commitment is associated with high satisfaction, poor alternatives, and substantial investments. Conversely, low commitment arises from unrewarding relationships or appealing alternatives.
Research Findings Supporting the Investment Model
Study Overview by Lur and Agnu
- Lur and Agnu conducted a comprehensive review of over 50 studies across various countries (U.S., U.K., Netherlands, Israel, Taiwan), examining links between satisfaction, investment size, alternatives, and commitment.
Key Findings from the Review
- Their findings indicate strong associations between satisfaction levels, investment size, low-quality alternatives with commitment levels. Satisfaction had the most significant influence followed by investment size; appealing alternatives negatively impacted commitment.
- Higher levels of commitment correlated with increased likelihood of staying in relationships while lower commitments were linked to higher chances of leaving. This evidence supports Roosevelt's investment model across diverse demographics and cultures.
