Psychometric properties of the Quality-of-Life Questionnaires (SF-36), (MLHFQ) Minnesota Living with Heart Failure Questionnaire among Congestive Heart Failure Patients

Introduction: The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is one of the most extensively used heart failure patient quality of life questionnaires (HF). It includes physical and emotional scores, as well as a total score. However, its factor structure has been questioned, and alternatives proposed, including a third factor expressing a social dimension. This Survey used to monitor population health, assess treatment outcomes, and estimate illness burden. Aims: Validation and testing of the SF-36 Quality of Life Questionnaire (QOLQ) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were the main objectives of this work in CHF patients. To identify the psychometric properties of the quality-of-life questionnaires (SF-36) and MLHFQ questionnaire among congestive heart failure patients Methodology: The quasi experimental study was conducted in those individuals who has suffered with heart failure (n= 36). These patients were admitted at the FIC, Faisalabad. The teach-back technique was introduced to teach about the self-care to improve the QOL of the participants. Every participant was administered the SF-36 and MLHFQ after intervention Post-test -1 was conducted at 30 days after accomplishment of the intervention with filling of both tools collected by the researcher/ facilitator on one-month clinical follow-up visit. Posttest-2 was conducted at 90 days after intervention at each participant on three-month follow-up visit. Results: The researcher were evaluated the questionnaires psychometric parameters, as well as the extent to which one may rely on the accuracy of a measurement, computation, or specification. (Internal consistency, test–retest analysis, and inter-item correlation). Exploratory factor analysis was used to determine the construct validity. Conclusion: It is found that the Urdu version of the Questionnaires (SF-36) and the MLHFQ questionnaire were proven to be a trustworthy and valid tool for improving quality of life in patients with congestive heart failure. With the use of these versions of the scale, assessing patient QOL, performance, has become smoother and readmission frequency in congestive heart failure Patients would become lesser.
