A Turkish version of myocardial infarction dimensional assessment scale (TR-MIDAS): reliability-validity assesment.Eur J Cardiovasc Nurs. 2011 Jun; 10(2):115-23.EJ
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.
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.
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.
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).
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.
