What is the self-expansion model and how do relationships promote personal growth?

• A. People maintain strictly separate self-concepts.
• B. The self-expansion model posits that people include their partner in their self-concept, expanding identities through shared experiences.
• C. Relationships hinder personal growth by limiting independence.
• D. Self-expansion only occurs after many years.

Answer: (B)

The self-expansion model holds that close relationships promote personal growth by expanding who we see ourselves to be. As couples share experiences, take on each other’s interests, and align goals, our identities grow to include aspects of both people. This inclusion of a partner into the self increases resources, perspectives, and capabilities—learning new skills, adopting new viewpoints, and gaining access to each other’s social networks. Because of this broadened self-concept, individuals often feel more confident, adaptable, and open to new challenges, which fuels ongoing personal growth. Importantly, this process doesn’t erase individuality; it enriches it by adding new dimensions from the relationship.
