Abstract
This study has been carried out to the relationship between perceived uncertainty and adherence in patients joining physical training program after myocardial infarction. The cross-sectional, correlational research design was selected, data were collected by the instruments which were consisted of the Mishel Uncertainty in Illness Scale and the Adherence Behavior Questionnaire. The subject consisted of 93 patients with myocardial infarction who had been undergone coronary angioplasty. Their ages ranged from 31 to 81 years, with an average of 64.0 years (SD=9.9 years).
Multiple regression analysis indicated that ambiguity, complexity, employed, male, a history of myocardial infarction, treadmill user, and exercise habit accounted for 43% of the variance in adherence. Patients with myocardial infarction have perceived uncertainty through the process of cognitive appraisal in a cardiac event. It is suggested that high levels of perceived uncertainty are directly related to low levels of adherence.
