<p>Despite the growing body of research on anxiety and intimate relationships, no studies have explored the association between symptoms of anxiety and relational connectivity, a construct focused on the depth of emotional closeness and mutual engagement in relationships nor the mediating effects of perceived partner responsiveness on these constructs. Using data from 81 mixed-gender couples sampled from the general population, this study investigated the association between anxiety and relational connectivity and the mediating roles of perceived partner responsiveness and insensitivity. The APIM results show intriguing differences in the roles of perceived partner responsiveness and perceived partner insensitivity as they mediate the intensity of anxious symptoms and their sense of relational connectivity. Notably, perceived partner insensitivity fully mediates anxious intensity and connectivity while responsiveness partially mediates this relationship. These findings highlight the complex interplay between anxiety and relational processes. This study contributes to the literature by extending our understanding of relational connectivity and its nuanced relationship with anxiety.</p>
