Abstract
<title>Abstract</title> <p>Interoception is increasingly recognised as a key contributor to socio-emotional functioning, yet its multidimensional links to distinct components of social cognition remain unclear. This study investigated how multiple dimensions of interoceptive awareness (IA) relate to empathy, Theory of Mind (ToM), and facial emotion recognition (FER) in 214 healthy adults, after excluding individuals with psychiatric, neurological, or substance-use conditions. Using a multidimensional network analysis approach, we modelled interdependencies among IA subscales and socio-cognitive measures to capture domain-specific patterns rather than isolated associations. The resulting network revealed strong connections between regulatory and interpretive IA dimensions, particularly Emotional Awareness, Self-Regulation, and Attention Regulation, and cognitive components of empathy. In contrast, IA showed only weak, indirect associations with ToM and FER. Noticing demonstrated high closeness and betweenness, suggesting a potential bridging role despite lower absolute edge weights. These findings highlight interoception as a multidimensional system with differential contributions to social cognition.</p>
