Towards a comprehensive assessment of interoception in a multi-dimensional framework

Interoception has historically been assessed using behavioural tests of accuracy, self-report measures or through the characterisation of neural signals underlying interoceptive processing. More recent conceptualisations of interoception incorporate interoceptive attention and higher-order measures related to the interpretation of interoceptive signals. At present, these interoceptive dimensions are largely assessed in isolation, yet this fails to capture the complexity of interoception. Comprehensive assessment across interoceptive dimensions can determine the full operation of general interoceptive function. Current work suggests that these interoceptive processes may be dissociable across dimensions and…
