Background
Relationships have been linked to significant physical health outcomes. However, little is known about the more specific processes that might be responsible for such links.
Purpose
The main aim of this study was to examine a previously unexplored and potentially important form of partner knowledge (i.e., attitude familiarity) on relationship processes and cardiovascular function.
Methods
In this study, 47 married couples completed an attitude familiarity questionnaire and ambulatory assessments of daily spousal interactions and blood pressure.
Results
Attitude familiarity was associated with better interpersonal functioning between spouses in daily life (e.g., greater partner responsiveness). Importantly, attitude familiarity was also related to lower overall ambulatory systolic blood pressure and diastolic blood pressure.
Conclusions
These data suggest that familiarity with a spouse’s attitudes may be an important factor linking relationships to better interpersonal and physical health outcomes.
