Notes. BPQ = Body Perception Questionnaire, MAIA-2 = Multidimensional Assessment of Interoceptive Awareness-2, PBCS = Private Body Consciousness Scale, BAQ = Body Awareness Questionnaire, BRS = Body Responsiveness Scale, ISQ = Interoception Sensory Questionnaire, IAS = Interoceptive Accuracy Scale. All ps < .001, except for the PBCS where p = .729.
