During
pregnancy many elements of the bodily experience change, suggesting that
measuring these constructs may require different instruments to those validated
in the general population. This study reports an exploratory and confirmatory
factor analysis exploration of the Multidimensional Assessment of Interoceptive
Awareness (MAIA) in 716 pregnant women (mean gestation 26.4 weeks), from six different
datasets who completed the MAIA online. Exploratory factor
analysis condensed the questionnaire from a 32- to a 19- item scale, with five
factor structure, which best fitted the data. Key subscales of Trust, Attention
Regulation, Self-Regulation and Not Distracting remained robust. The one
remaining item from the Noticing subscale loaded heavily with the Emotional
Awareness subscale. Subscales of Body Listening, Not Worrying and Noticing did
not load and therefore were excluded as factors. This led to the development of
the scale referred to as the MAIA-Preg, which demonstrated a good fit with a
confirmatory factor analysis along with good subscale reliability (ω= 0.73 - .92), and measurement invariance for
second and third trimesters. The MAIA-Preg was also found to be a good fit for
separate non-pregnant (N = 396) and postnatal (N = 174) samples and thus
provides a reliable and valid measure, providing nuanced information about the
bodily experience in perinatal populations, allowing comparisons of changes to
interoceptive sensibility the perinatal period.
