Validation of the Factor Structure and Psychometric and Clinical Properties of the Multidimensional Emotional Disorder Inventory (MEDI) – German Version

Abstract: The Multidimensional Emotional Disorder Inventory (MEDI) is a brief, transdiagnostic measure assessing nine dimensions of emotional disorders. This study evaluated the psychometric and clinical properties of the German version of the MEDI in a large sample ( N = 1,129) including healthy individuals and patients from two outpatient psychotherapy clinics. The results showed high internal consistency (Cronbach's α = .73–.92) and acceptable test–retest reliability ( r tt = .58–.78) over a 7-month interval. Exploratory structural equation modeling confirmed the original nine-factor model, although with reduced consistency for the Avoidance scale. Correlations with established symptom and personality measures, as well as clinical diagnoses, indicated good convergent and discriminant validity. Overall, the MEDI – German version demonstrated good psychometric properties, making it suitable for evaluating therapeutic interventions for emotional disorders in clinical practice and research.
