Multidimensional emotional disorders inventory: Reliability and validity in a Spanish clinical sample

Area of Science:

• Psychiatry
• Clinical Psychology
• Psychometrics

Background:

• The categorical approach to mental disorder diagnosis faces criticism due to high comorbidity and numerous diagnostic categories.
• Dimensional and hybrid approaches offer alternatives to traditional diagnostic methods.
• The Multidimensional Emotional Disorders Inventory (MEDI) is a tool for assessing transdiagnostic dimensions of emotional disorders using a hybrid approach.

Purpose of the Study:

• To explore the validity and reliability of the 49-item MEDI in a Spanish clinical sample.
• To provide data supporting the use of the MEDI in Spanish mental health settings.

Main Methods:

• 280 outpatients with emotional disorders from Spanish Mental Health Units participated.
• Participants completed questionnaires assessing personality, mood, anxiety, and avoidance.
• The MEDI was administered at assessment and one week later to evaluate reliability and stability.

Main Results:

• The original nine factors of the MEDI were confirmed with adequate reliability (α: 0.66-0.91) and stability (r = 0.76-0.87).
• No significant sex differences were found in MEDI subscale scores (p ≥ 0.07).
• MEDI subscales showed significant correlations with measures of personality, mood, anxiety, and avoidance (0.45 < r < 0.76).

Conclusions:

• The MEDI demonstrates sufficient reliability and validity for use in Spanish clinical samples.
• The inventory efficiently assesses diverse emotional disorder symptoms, making it valuable for clinical research and practice.
