Description

The Minnesota Living with Heart Failure Questionnaire (MLWHFQ-21) is an assessment tool used to evaluate the quality of life in patients with heart failure. This study focuses on a detailed analysis of the data derived from the use of the MLWHFQ-21, assessing its usefulness in monitoring disease progression and the impact of therapeutic interventions on patients’ quality of life.

Objective

The main objective of this study is to evaluate the effectiveness of the MLWHFQ-21 as a tool for measuring quality of life in heart failure patients by analyzing the data obtained through its use. This analysis includes the examination of the tool’s validity, reliability, and sensitivity in detecting changes in patients’ quality of life.

Calibration

The calibration of the MLWHFQ-21 is performed through statistical analyses, including measurements of internal consistency (e.g., using Cronbach’s alpha), test-retest reliability, and validity of the instrument. The analysis also includes comparisons with other quality of life assessment scales, such as the EQ-5D or the SF-36.
