Studies investigating the potential structures underlying the connection between mindfulness and romantic relationship quality are not sufficient and require additional empirical findings. The current study aimed to examine a hypothesized model underlying the association between mindfulness and relationship quality, while investigating the roles of individuals' level of awareness and application of care in a romantic relationship among 199 adult participants in a southeastern region of the United States. Structural equation modeling (SEM) and path analysis were executed to examine the hypothesized structural model, testing a multi‐step pathway as to how mindfulness influences relationship quality. The SEM and path analyses showed a good fit for the present study's hypothesized model, indicating that individuals' mindfulness had a direct influence on their self‐awareness level. Individuals' self‐awareness and application of care mediated the link between mindfulness and relationship quality. Implications for family life educators, dyadic couples researchers, and marriage and family practitioners are discussed.
