The Minimal Eating Observation Form-Version II Revisited: Validity and Reliability

Area of Science:

• Gerontology
• Clinical Nutrition
• Psychometrics

Background:

• Eating difficulties are prevalent in older adults, impacting health and quality of life.
• Screening tools are essential for early identification and intervention.
• The Minimal Eating Observation Form-Version II (MEOF-II) is a tool for assessing eating difficulties.

Purpose of the Study:

• To evaluate the psychometric properties of the Minimal Eating Observation Form-Version II (MEOF-II).
• To establish the reliability and validity of the MEOF-II for screening eating difficulties.

Main Methods:

• Cross-sectional study of 5,956 individuals, including nursing home residents and in-hospital patients.
• Analysis of dichotomous item-level data using tetrachoric correlations.
• Factor analysis to assess the structure of the MEOF-II.

Main Results:

• The MEOF-II demonstrated a unidimensional higher-order factor structure (61.7% explained variance, omega 0.92).
• Three lower-level factors were identified: deglutition, ingestion, and energy/appetite (92.9% explained variance, omega 0.83-0.88).
• High reliability and validity were found for the total scale and subscales.

Conclusions:

• The MEOF-II is a reliable and valid tool for assessing eating difficulties.
• Findings support the use of MEOF-II in clinical practice and research for older adults.
• The study confirms previous findings on the tool's psychometric properties.
