Abstract
Background: Many new measuring devices have been developed so that broader psychometric measurements in the coronary artery disease, disease-specific health status measurements, and identification of the broader quality of life can be performed in the recent years.
Aims: The study was intended to determine whether, and to what extent, MIDAS is a valid and reliable measurement to the patients suffering from myocardial infarction for the first time in Turkey.
Methods: The research was conducted with the patients hospitalized and treated with myocardial infarction in the cardiology departments of 2 hospitals in Istanbul, Turkey, between 2007 and 2008. Psychometric evaluations of TR-MIDAS were used for validity studies; language validity, content validity, construct validity were examined. For reliability studies; the tool's internal consistency reliability, Cronbach's alpha reliability coefficient, and test–retest reliability were completed.
Results: The instrument's content validity index was determined to be “0.95”. Principal component analysis revealed six factors with an eigenvalue > 1.5. Cronbach's alpha was found to be 0.89 for total scale which was an acceptable value. The total's test–retest reliability was 0.51 (p < 0.01).
Conclusion: Data obtained at the end of the study supports that Turkish Myocardial Infarction Dimensional Assessment Scale is a valid and reliable instrument as a disease-specific scale to assess the patients' quality of life suffering from myocardial infarction in Turkey.
