Questionnaire-Description

The QLMI is a questionnaire that aims to evaluate the quality of life of individuals who have experienced a myocardial infarction. This scale takes into account various aspects of life that can be affected by a heart attack, such as:

Physical health: Ability to perform daily activities, levels of fatigue, and pain.

Emotional well-being: Depression, anxiety, concerns about health.

Social functioning: Level of social interaction and support from family and friends.

Functional capacity: Ability to return to normal daily activities and work.

The scale consists of various questions related to symptoms, feelings, and lifestyle changes after the cardiac event. Responses are provided using a Likert scale, allowing for the assessment of variations in quality of life.

Data Analysis and Usage

The data collected from the QLMI are analyzed to assess patients’ quality of life post-myocardial infarction. This information can be used to:

Monitor patients’ progress during recovery.

Evaluate the effectiveness of therapeutic interventions, such as medication, diet, physical exercise, and psychosocial support.

Identify areas where patients may need further support or intervention.

Analyses include:

Statistical analysis to determine which dimensions of quality of life are most affected after a myocardial infarction.

Reliability analysis (e.g., Cronbach’s alpha) to assess the internal consistency of the questions.

Multivariate analysis to determine the impact of various factors, such as age, gender, and the severity of the infarction, on patients’ responses.

Purpose

The primary goal of the QLMI is to assess how a myocardial infarction affects various aspects of patients’ lives. Specifically, it aims to:

Identify changes in quality of life that arise after a cardiac event.

Determine patients’ needs for better adaptation and rehabilitation.

Assist healthcare professionals in providing comprehensive care aimed at improving patients’ overall quality of life.

Calibration

The calibration of the QLMI involves:

Reliability analysis to measure the internal consistency of responses across the various categories of the questionnaire.

Confirmatory factor analysis to ensure that the scale measures the expected dimensions of quality of life.

Validation in different patient populations to ensure that the questionnaire is suitable for widespread use in various settings and conditions.
