ROMERO MASSA, Elizabeth. Reliability of the SF-36 questionnaire in post acute myocardial infarction patients from the city of Cartagena de Indias, Colombia. Rev. Colom. Cardiol. [online]. 2010, vol.17, n.2, pp.41-46. ISSN 0120-5633.

Background: the SF-36 survey questionnaire is one of the most widely used generic instruments in studies for measuring the impact on quality of life in relation to the health in different patient populations. However, its internal consistency in patients with acute myocardial infarction in different age and sex groups of four ICUs in the city of Cartagena, Colombia, is not known. Objective: to determine the reliability of the SF-36 health questionnaire in order to assess life quality in patients after acute myocardial infarct in four ICUs in the city of Cartagena. Method: we designed a methodological study that addressed the development as well as the validation and evaluation of the instrument. A group of 100 patients who developed acute myocardial infarction filled out the SF-36 questionnaire. The reliability was determined by the Cronbach's alpha test that measures the consistency of scales through polytomic pattern responses. Results: the reliability of the SF-36 health test obtained a Cronbach alpha coefficient with values ranging from 0.74 to 0.93. Conclusions: the SF-36 is reliable for assessing the life quality in patients who have suffered an acute myocardial infarct.
