Hope, depressive symptoms, anxiety, and physical quality of life (QOL) were assessed in three subgroups of patients receiving the gastric pacemaker. Patients (n= 22) completed questionnaires prior to pacemaker implantation and at 3 and 6 months post-surgery. The idiopathic subgroup reported a significantly greater degree of hope and less anxiety at 6-month follow-up, compared to the diabetes patients. The idiopathic patients also reported significantly less anxiety at 6 months than the postsurgical patients. Across all subgroups, there was an increase in hope and physical QOL, and decrease in depressive symptoms and anxiety, from baseline levels. There was a significant negative relationship between hope and both depressive symptoms and anxiety at baseline and 3- and 6-month follow-up. Presurgical hope level did not significantly predict depressive symptoms or anxiety after implantation. This study provides evidence that the pacemaker improves the physical and psychological health of gastropareutic patients; hope appears to play a role in the psychological adjustment of these patients.
