Multidimensional assessment of interoceptive awareness (MAIA 2): psychometric properties of the Turkish version

Abstract

Aim: Interoception, defined as the perception of internal bodily changes. The aim of this study is to evaluate the Turkishvalidity and reliability study of the Multidimensional Assessment of Interoceptive Awareness-2 (MAIA 2) scale developed byWilliam Mehling et al. (2018).Material and Method: The research is methodological. Research data was collected between April 2020 and May 2020 (n=400).Forward and backward translation were used to translate the MAIA 2 into Turkish. We conducted exploratory factor analysis(EFA) and confirmatory factor analysis (CFA) to analyze the psychometrics of the MAIA 2 in a 70:30 split sample. Statisticalanalysis were done with R Project.Results: The Kaiser-Meyer-Olkin value (KMO=0.910) was acceptable, and there exists a significant correlation structure withBartlett’s test of sphericity (χ2=5134.120, p<0.001). We observed six factors with Horn’s Parallel analysis. The Cronbach Alphasof these six factors were acceptable (α>0.60). Standardized loadings were positive and >0.40 with significant results (p<0.05)(r=0.71, p<0.05). The RMSEA is nearly zero and SRMR is extremely low.Conclusions: As a result, the Turkish version of the Multidimensional Assessment of Interoceptive Awareness Scale (MAIA 2)developed by Mehling et al. and originally in English is valid and reliable according to our results.
