Abstract
In this study, we examined an unexplored type of partner knowledge—familiarity with partners’ subjective well-being (i.e., SWB familiarity). Using multilevel models, we analyzed data from 101 heterosexual couples to examine how SWB was associated with partner knowledge and to determine whether SWB familiarity was associated with relationship and mental health benefits. We found that higher levels of positive affect and life satisfaction and lower levels of negative affect were associated with greater normative and distinctive accuracy in partner knowledge of attitudes and traits. We also calculated both normative and distinctive indices of SWB familiarity and found that participants’ and their partners’ familiarity with normative (i.e., average) profiles of SWB were associated with respondents reporting greater relationship satisfaction, perceived support from their partner, positive affect, and life satisfaction, as well as less negative affect. Conversely, distinctive (i.e., unique) SWB familiarity was not related to any relationship or mental health outcomes. Thus, one’s perception of their partner as having normative levels of SWB appears to be more important for relationship and mental health outcomes than knowledge of partners’ unique experiences of SWB.

Notes
While this study found that attitude familiarity was significantly associated with less interpersonal stress, this association disappeared when attitude similarity was entered as a predictor as well.
For reference, we also computed the overall level of partners’ similarity for attitudes, traits, and SWB. Participants’ attitude similarity ranged from -.41 to .82 (M = .34, SD = .25). Participants’ trait similarity ranged from -.49 to .87 (M = .31, SD = .29). Participants’ SWB similarity ranged from -.65 to .97 (M = .48, SD = .27). On average, people were fairly similar to their partners in terms of attitudes, traits, and SWB, as indicated by these average positive correlations.
Across these analyses, we did not find evidence for moderation of our effects by age, gender, or relationship length.
Across these analyses, we did not find consistent evidence for moderation of our effects by age, gender, or relationship length. There were no significant interactions between age, gender, or relationship length and our indices of distinctive SWB familiarity. There were a handful of significant interactions between age, gender, and relationship length and normative SWB familiarity, however these interaction effects did not emerge consistently across analyses. Interested readers can email the authors for more information about these effects.
All significant effects held when controlling for partner subjective well-being (i.e., partner PA, partner NA, or partner LS).
