Happy couples “see” helpful partners: Relationship quality predicts biased perceptions of partner instrumentality to one's goals.

Perceiving a romantic partner as instrumental to one's goals predicts myriad desirable relationship outcomes. However, little is known about the origins of perceived partner instrumentality (PPI)—particularly about factors that may bias PPI. In two studies, we provide evidence supporting the hypothesis that relationship quality predicts biased PPI. In a dyadic correlational study (Study 1) and an imagined scenario study in which we experimentally manipulated partner instrumentality levels (Study 2), participants reporting higher relationship quality perceived their partners as more instrumental to their goals—even when controlling for depressive symptoms, and when controlling for partner‐reported (Study 1) or enacted partner (Study 2) instrumentality. Additionally, in Study 1 (but not Study 2), relationship quality attenuated a negative association between depressive symptoms and PPI. Study 2 also revealed that perceiving a partner as more instrumental predicted greater intentions to provide instrumental support to that partner in the future. These findings fill important gaps in the instrumentality and relationships literature, identifying antecedents of PPI and offering insights into how PPI may predict relationship functioning.
