Abstract
Scale measuring the construct of "health security in chronic illness" (HSCI) was piloted in Canadian cardiac device patients (N = 176) enrolled in a remote-monitoring study at 2 timepoints. Analysis revealed a 2-factor solution, labeled as "support" and "certainty". Patients reported receiving less support over time, but consistent health certainty. Patients with implantable cardioverter defibrillators felt less secure over time and reported lower levels of health security in chronic illness than pacemaker patients.
