title: Role of health locus of control between uncertainty and uncertainty appraisal among patients with atrial fibrillation.
abstract: The purpose of this study was to determine the role of health locus of control in the model of uncertainty in illness among patients with atrial fibrillation. This study employed a descriptive, correlational survey. A total of 81 patients with atrial fibrillation were recruited from two large medical centers in the United States. Only the interaction term of uncertainty and internal health locus of control had a significant moderating effect on appraisal of danger. Greater internal health locus of control was associated with greater appraisal of danger at the given degree of uncertainty. Therefore, the internal health locus of control played a significant role in magnifying the relationship of uncertainty on appraisal of danger. However, health locus of control did not moderate the relationship between uncertainty and appraisal of opportunity. Finally, this study concluded that internal health locus of control had a moderating effect on the relationship between uncertainty and appraisal of danger.
