The development of communication behavior over the newlywed years

Communication behavior occupies a fundamental role in basic and applied relationship science, yet we know very little about how this important process develops over time, and how the natural developmental process is linked with relationship outcomes. The present study aims to examine the development of naturally occurring trajectories of couple communication behavior across three domains, examined concurrently; positive affect, negative affect, and effective problem solving. A large sample of newlywed couples recruited from low-income neighborhoods (N = 431) completed observational discussion tasks at 4 time points, spanning 2.5 years, and provided data on marital status 4.5 years into marriage. Results from multivariate group-based trajectory modeling indicate that three groups of couples can be distinguished, with the best communicators demonstrating high levels of positivity and effectiveness and low levels of negativity, the worst communicators demonstrating low levels of positivity and effectiveness and high levels of negativity, and the middle group demonstrating low levels of all three dimensions. Trajectory group membership was significantly associated with demographic and relationship characteristics, such that the best communicators had more adaptive relationship characteristics and less demographic risk. Wives' trajectory group membership was significantly associated with divorce rates such that the best communicators had the lowest divorce rate (9%), and the worst communicators had the highest divorce rate (22%). Overall, communication behavior is quite consistent over time, indicating that early interaction dynamics tend to be enduring and predictive of relationship outcomes.
