Interoceptive awareness refers to the conscious perception of internal bodily states. The aim of the present work was the validation of the Multidimensional Assessment of Interoceptive Awareness (MAIA).
The data was collected from a non-probabilistic sample of 755 subjects. The MAIA is originally constituted by 32 items (divided in eight dimensions) with the possibility of response being on a 6-point Likert scale. The study of the metric qualities of this instrument was made in two different subsamples by using exploratory (N = 376) and confirmatory factor analysis (N = 379).
A structure different from the original was obtained, which maintains the psychological meaning and adequate validity, sensitivity and reliability.
Four dimensions present in the original version were obtained (Attentional Regulation; Emotional Awareness; Body Listening; Trusting).
