How Relationship Satisfaction and Negative Communication Trajectories Change in Emerging Adults' Dating Relationships: A Group-Based Dual Trajectory Analysis.

Early romantic relationships are salient to the development of healthy future relationships. Yet, little is known about the evolution of romantic relationships of emerging adults since most of the research has been conducted on married or well-established couples. The current study aims to examine how relationship satisfaction and negative communication evolve and are interrelated during emerging adulthood. Using age as a time metric, we conducted group-based dual trajectory modeling analyses on 1566 unmarried Canadian individuals (from 17 to 24 years old) in a relationship, who could either stay with the same partner or change partner over time. A four-group model for relationship satisfaction and a four-group model for negative communication were found. Dual analyses highlighted the high concordance between specific trajectories of both constructs. These findings demonstrate that relationship satisfaction and negative communication do not evolve in the same ways for everyone and provide useful insights to existing clinical interventions.
