Relationship perceptions and persistence: Do fluctuations in perceived partner commitment undermine dating relationships?

The authors propose specific temporal profiles that reflect certainty versus doubt about where a partner stands with respect to a dating relationship over time. Two multiwave longitudinal studies focused on within-participant changes in perceived partner commitment. Results from multilevel modeling indicate that individuals whose perceptions of partner commitment fluctuate over time were more likely to be in a relationship that eventually ended than were individuals whose perceptions remained relatively steady. For individuals in recently initiated relationships, the association of fluctuation in perceived partner commitment with later breakup was significant regardless of the initial level of perceived partner commitment or the trend, and for all participants, it remained significant when initial level, trend over time, and fluctuation over time of other meaningful variables were controlled.
