OBJECTIVES
It is well known that myocardial infarction (MI) adversely affects health-related quality of life. This study was designed to investigate the validity and reliability of the Turkish adaptation of the Myocardial Infarction Dimensional Assessment Scale (MIDAS) in patients admitted to hospital following their first MI.

STUDY DESIGN
The study included 81 patients (13 women, 68 men; age ≤70 years) who were treated for their first MI, with recovery from the acute period without chest pain. Data were collected using a questionnaire on sociodemographic features and the Turkish version of the MIDAS. Validity studies included language and content validity. For reliability analyses, Cronbach’s alpha coefficients were calculated and, for test-retest reliability, the scale was re-administered after a two-week interval.

RESULTS
The participants fell within the following age brackets: 30-44 years (9.9%), 45-54 years (40.7%), 55-64 years (27.2%), and 65-70 years (22.2%). Content validity index of the scale was 0.95. The overall Cronbach’s alpha coefficient was calculated as 0.83, ranging from 0.31 to 0.91 for seven subscales. Item-total correlations were between 0.31 and 0.91. The overall test-retest reliability was 0.45 (p=0.00), ranging from 0.27 to 0.74 for seven subscales.

CONCLUSION
This has been the third study evaluating the MIDAS in MI patients. Our results demonstrate that the Turkish version of the MIDAS can be used as a valid and reliable tool in the evaluation of disease-specific quality of life of Turkish patients sustaining their first MI.
