The ups and downs of dating: fluctuations in satisfaction in newly formed romantic relationships.

This research examined the association between relationship satisfaction and later breakup status, focusing on the temporal changes in satisfaction ratings of individuals in newly formed dating relationships. Growth curve analytic techniques were used in 2 longitudinal studies to create 4 predictors: each participant's initial level of satisfaction, linear trend in satisfaction over time, degree of fluctuation in satisfaction over time, and mean level of satisfaction. Consistent with hypotheses, individuals who exhibited greater fluctuation in their repeated satisfaction ratings were more likely to be in relationships that eventually ended, even after controlling for overall level of satisfaction. Individuals with fluctuating levels of satisfaction also reported relatively lower commitment. The results are discussed in terms of conditions that promote versus undermine relationship stability.
