Flourishing Together: The Longitudinal Effect of Goal Coordination on Goal Progress and Life Satisfaction in Romantic Relationships.

Goal pursuit shapes people' everyday experiences and is deeply embedded within close relationships. Several studies have shown that goal support from romantic partners facilitates goal progress, and individual goal progress contributes to wellbeing. However, few pieces of research have examined the whole process, how efficient goal coordination in a romantic relationship contributes to life satisfaction through goal progress. In these studies, short time frames were used and only one aspect of goal coordination was examined. To generate more complex, long-term understanding we collected data from 148 married or cohabitating Hungarian heterosexual couples (mean age 39.71 ± 10.40 and 38.57 ± 10.00 years for men and women, respectively) in a two-wave longitudinal study with a year-long time window. Both partners individually completed an adapted version of the Personal Project Assessment and evaluated four chosen projects associated with project coordination (emotional support, communication, and cooperation) at baseline, and project attainment (progress, success, satisfaction) in the follow up. Life satisfaction was assessed during both waves. Results from the actor-partner interdependence mediation modeling revealed complete mediation, where project coordination increased project attainment one year later, and consequently associated with higher life satisfaction for both partners. The direct effect between project coordination and life satisfaction remained nonsignificant. This association indicates that for long-term life satisfaction, it is crucial to experience better goal outcomes as the result of the couple's collaborative effort.
