Review of Literature (Assignment – Essay)

Depression and Perceived Control in Patients having Coronary Artery Bypass Grafts. Journal of Advanced Nursing, 65 (11), 2386–2396. This article aims at finding out the course of anxiety, depression, and control of perceptions and the influence the control of perceptions has on patients undergoing bypass grafts of the coronary artery before, after surgery at the hospital, and 2 weeks after being discharged. A descriptive design that is prospective in nature was used for the study using a convenient sample of patients with the condition requiring surgery (n = 155). The Hospital’s Anxiety and Depression Scale and Control Attitudes Scale were used to measure anxiety and depression and perceptions of control over the illness respectively before and after surgery (during hospital stay) and 2 weeks after discharge. The limitations were the use of a convenience sample and loss of participants for subsequent interviews. Moreover, designs involving anxiety, depression and control concurrently do not imply casualty due the likelihood hood of bidirectional effects.
