The validation study of Finnish MAIA-2
The Multidimensional Assessment of Interoceptive Awareness 2 (MAIA-2) is a self-report questionnaire that consists of 37 items aimed to measure subjective interoceptive awareness. In this study, the Finnish translation of MAIA-2 was validated to Finnish general population (n = 285). For that purpose, the factor structure and psychometric properties of the questionnaire were examined. The results were compared to the original validation studies and validation studies conducted in other countries. The analysis methods used to examine the psychometric properties of MAIA-2 were exploratory and confirmatory factor analysis, Cronbach alpha coefficient and Pearson’s correlation coefficient. The fit indices were compared to the original validation studies and commonly accepted cut-off criteria. To examine the convergent and divergent validity of the scale, the correlations were calculated between MAIA-2 and three other psychological inventories: Five Facet Mindfulness Questionnaire (FFMQ), Difficulties in Emotion Regulation Scale (DERS) and Pain Catastrophizing Scale (PCS).
