A developmental perspective on personality-relationship transactions : evidence from three nationally representative samples

Abstract

Objective Throughout their lives, people experience different relationship events, such as beginning or dissolving a romantic relationship. Personality traits predict the occurrence of such relationship events (i.e., selection effects), and relationship events predict changes in personality traits (i.e., socialization effects), summarized as personality–relationship transactions. So far, evidence was partly inconsistent as to how personality traits and relationship events are linked with each other. In this article, we argue that unnoticed age differences might have led to these inconsistencies. To systematically test for age differences in transactions, we conceptualize relationship events in terms of gains and losses and apply a developmental perspective on transactions.

Methods Using longitudinal data from three nationally representative samples (SOEP, HILDA, Understanding Society), we computed event-focused latent growth models and summarized the results meta-analytically.

Results The findings indicated some transactions. Of these, selection effects were stronger than socialization effects, and effects of gain-based events were stronger than effects of loss-based events. We observed few interactions with age.

Conclusion Selection effects and, particularly, socialization effects, tend to be rare and fairly independent of age. We discuss a series of broader and narrower factors that may have an impact on the strength of transactions across adulthood.
