Interdependence of Approach and Avoidance Goals in Romantic Couples Over Days and Months

Objectives: Despite the centrality of people's approach goals (i.e., approach toward positive outcomes) and avoidance goals (i.e., avoidance of negative outcomes) in romantic relationships, little is known about the interdependence of approach and avoidance relationship goals between partners. Assuming that short-term, state-level goals accumulate into general goal ten- dencies, the present research tested whether partners' daily (i.e., state level) and aggregated daily (i.e., trait level) approach and avoidance goals are mutually predictive in the short term (after one day) and the long term (after 10-12 months). In addition, we explored whether goal interdependence unfolds differently across adulthood and in relationships of different duration. Method: Approach and avoidance goals were assessed daily on two 14-day measurement-burst occasions that were con- ducted 10-12 months apart. The sample consisted of N = 456 female-male couples (age: M = 33.6, SD = 13.8 years; rela- tionship duration: M = 9.6, SD = 10.7 years). Results: We observed significant short- and long-term partner effects in the prediction of couple members' approach and avoidance goals. These partner effects were restricted to trait level and they did not emerge at the state level. Almost all ef- fects were independent of age and relationship duration. Discussion: The present research underscores the importance of disentangling state- and trait-level goal tendencies when investigating the interdependence of approach and avoidance goals within romantic relationships.
