I hope my partner can make me change: expected relational self-changes and relational outcomes.

The Two-Dimensional Model of Relational Self-change (TDM) suggests four types of self-change that may be elicited by romantic relationships: self-expansion, self-adulteration, self-pruning, and self-contraction. Previous research has shown that these four types of relational self-change were associated with relational outcomes. Prior research has also shown that positive illusions and expectations in romantic relationships can lead to positive relational outcomes. The current study used a longitudinal design to investigate how the four types of expected relational self-change affect future relationship satisfaction and commitment. Results indicated that participants had higher expected self-changes than their actual self-changes after three months, but their expected self-changes and actual self-changes were correlated. At Time 1 of their relationship, participants' relationship satisfaction and commitment were related to their expected self-changes. However, controlling for Time 1 relationship satisfaction and commitment, expected self-changes predicted commitment, but not relationship satisfaction, three months later.
