Marriage as a training ground: Examining change in self-control and forgiveness over the first 4 years of marriage.

Do partners' levels of self-control and forgiveness change over the course of marriage? Based on the idea that marriage may function as a training ground for these vital relationship abilities, we hypothesized that people increase their levels of self-control and forgiveness over time and that these developments take place simultaneously. We tested these predictions among 199 newlywed couples in the first 4 years of marriage, using a dyadic latent growth curves analysis. Confirming our hypotheses, results showed significant increases in self-control and forgiveness as well as a positive concurrent correlation between these variables. However, the developments of self-control and forgiveness were unrelated. So, while people become more self-controlled and forgiving over the course of a marriage, these developments do not coincide.
