King’s Theory of Goal Attainment: Quality of Life for People With Myocardial Infarction

The aim of this study was to evaluate the effects of a theory of goal attainment-based care plan on quality of life among patients with myocardial infarction. One hundred two patients were randomly assigned to two groups. The intervention group received a theory of goal attainment-based care plan during their hospital stay and a two-month follow-up assessment after hospital discharge. Quality of life was assessed using the Persian version of the MacNew Heart Disease Health-Related Quality of Life questionnaire. Despite no significant difference between the groups with respect to the pretest mean scores of quality of life and its dimensions (p > .05), the posttest mean scores of quality of life and its dimensions in the intervention group were significantly greater than those of the control group (p < .001). Moreover, while the mean scores of quality of life and its dimensions significantly increased in the intervention group (p < .001), they did not significantly change in the control group (p > .05), except for the mean score of physical functioning (p = .032).
