Key result
The Greek version of the Minnesota Living With Heart Failure Questionnaire demonstrated high internal consistency (total scale 0.95) and a 3-factor structure explaining 64.15% of the variance.
Cross-Sectional (n=128)
The Greek version of the MLHFQ is a valid and reliable tool for assessing health-related quality of life in Greek-speaking heart failure patients.
Supports Greek MLHFQ for HRQoL assessment in HF; extends validation to a new linguistic population.
In Brief PURPOSE: One of the major challenges for health care professionals in heart failure (HF) management is to maintain and/or improve HF patient health-related quality of life. The Minnesota Living With Heart Failure Questionnaire (MLHFQ) is one of the most comprehensive and widely used tools for measuring health-related quality of life among patients with HF. The aim of the study was to assess the psychometric properties of the Greek version of the tool. METHODS: The MLHFQ was administered among 128 Greek-Cypriot HF patients to assess the internal consistency, content validity, and contrast validity of its Greek version. Exploratory factor analysis was undertaken to establish its construct validity. RESULTS: The factor analysis in this study provided support for a 3-factor solution explaining 64.15% of the variance (physical, emotional, and social subscales). The internal consistency for the Greek version of the MLHFQ total scale (0.95) and subscales (0.80–0.94) were found to be high. The contrast validity of the Greek version of the MLHFQ was explored through cumulative MLHFQ scores and comparisons that were able to distinguish among all different levels of HF severity, as defined by the New York Heart Association functional class grouping. CONCLUSION: This study provides support for the reliability and validity of the Greek version of the MLHFQ. This study evaluates the psychometric properties of the Minnesota Living With Heart Failure Questionnaire in a Greek-speaking population. The Greek version of the tool demonstrated adequate validity and reliability measures; thus, it can be used in heart failure research.

Lambrinou et al. (2013) conducted a cross-sectional in Heart failure (n=128). Greek version of the Minnesota Living With Heart Failure Questionnaire was evaluated on Psychometric properties including internal consistency and construct validity. The Greek version of the Minnesota Living With Heart Failure Questionnaire demonstrated high internal consistency (total scale 0.95) and a 3-factor structure explaining 64.15% of the variance.
