The Investment Model in relationships psychology explains how satisfaction, quality... Show more
Satisfaction in a relationship is based on the comparison level, which is influenced by previous relationship experiences.
Example: Partners are generally satisfied when they perceive they are getting more out of the current relationship than they expected based on past experiences.
This component involves evaluating whether one's needs can be better met outside the current relationship.
Vocabulary: The "alternative" can refer to another relationship or even being single.
Investments are arguably the most crucial component of the model. They can be categorized into two types:
Highlight: Investments help explain why dissatisfied partners may stay in a relationship โ they are committed due to the resources they've invested and don't want to waste.
Rusbult's model emphasizes that commitment, not satisfaction, is the primary factor in relationship stability. This distinction is crucial for understanding why some people remain in unsatisfying relationships.
Example: A partner might stay in a relationship despite low satisfaction because they have invested significant time, energy, or resources, making them more committed to maintaining the relationship.
The Investment Model helps explain the complex dynamics of relationship commitment, going beyond simple satisfaction to consider the role of alternatives and investments in shaping long-term relationship outcomes.
Le and Agnew conducted a meta-analysis that provides strong support for Rusbult's Investment Model.
Highlight: The meta-analysis reviewed 52 studies from the late 1970s to 1999, including participants from five countries.
Key findings:
This research suggests validity in Rusbult's claims and highlights the model's universality.
One limitation of the Investment Model is the correlational nature of its supporting research.
Definition: Correlational research demonstrates a relationship between variables but cannot prove causation.
This limitation raises questions about the direction of the relationship between investments and commitment:
The model may identify factors associated with commitment rather than its direct causes.
Critics argue that Rusbult's concept of relationship investment is oversimplified.
Example: Goodfriend and Agnew suggest that future plans, not just past investments, significantly influence commitment.
The original model may be limited in recognizing the true complexity of investment, particularly how planning for the future affects commitment in relationships.
Vocabulary: Reductionism refers to the practice of analyzing complex phenomena by breaking them down into simpler, more fundamental parts.
Understanding these evaluations helps in appreciating both the strengths and limitations of the Investment Model in relationships psychology, providing a more comprehensive view of its application and implications in understanding commitment and relationship stability.
The Investment Model, developed by Caryl Rusbult, is a psychological framework that explains the factors contributing to commitment and stability in romantic relationships. This model addresses limitations in social exchange theory by emphasizing the central role of commitment.
Definition: Commitment in this context refers to a romantic partner's intention or desire to continue a relationship, reflecting a belief that the relationship has a viable long-term future.
The Investment Model identifies three key components that influence commitment:
These factors work together to determine the level of commitment in a relationship, which in turn affects its stability.
Highlight: Rusbult argues that commitment, rather than satisfaction, is the main psychological factor causing people to stay in a relationship.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better.
