Validation of the Multidimensional Assessment of Interoceptive Awareness (MAIA-2) questionnaire in hospitalized patients with major depressive disorder

Objectives Interoception refers to the sensation, interpretation, and integration of internal somatic signals. Abnormalities in self-reported interoception are prevalent features major depressive disorder (MDD) may affect treatment outcomes. In present study, we investigated psychometric properties revised eight-dimensional 37-item Multidimensional Assessment Interoceptive Awareness questionnaire (the MAIA-2) a severely depressed sample, after translating two updated scales (Not-Distracting, Not-Worrying) into German. Specifically, examined measure’s consistency reliability, sensitivity change, minimal important differences (MID) with focus on patient’s antidepressive responses treatment. Methods The study enrolled 110 participants (age: M = 46.85, SD 11.23; female: 55.45%) undergoing hospital treatment, whom 87 were included pre-post analysis. Participants completed German translation MAIA-2 Beck Depression Inventory-II (pre-/post-treatment). Internal reliability was determined by Cronbach’s ? /McDonalds’s ? , change effect sizes, MIDs distribution- (0.5* ) anchor-based approaches (mean method; ROC curve cut-points). Results severity reduced over course (Median -65.22%), 34.48% patients achieved remission. Reliability appropriate for post-treatment (range : .70-.90), but questionable pre-treatment (Noticing: .64; Not-Distracting: .66). eight dimensions sensitive (standardized response mean: .32-.81; Cohen’s size: .30-.92). Distribution-based (.38-.61) mean (remission vs. partial response: .00-.85; nonresponse: .08-.88) established group level. For six scales, cut-points (remission: .00–1.33; -.20–1.00) demonstrated accurate classification groups individual Conclusions This applicability MDD. version have led improvements regarding subthreshold evident prior change. that corresponded Our findings consistent growing area research which considers feelings as key contributors mental health.
