Predicting Role of Patients Pre-operative Knowledge and Self-efficacy on their Post Operation Anxiety, Depression and Vision-related Quality of Life among the Elderly Patients Undergoing Retinal Surgery

Objective: Macular degeneration and subsequent retinal detachment is one of the most common disorders in the elderly which is treated with surgery. Performing eye surgery leads into psychological distress and affects the lives of the patients. The current study is an attempt to determine the predicting role of patients’ pre-operative knowledge and self-efficacy on their post operation anxiety, depression and vision-related quality of life among the elderly patients undergoing retinal surgery in Shiraz. Method: in this descriptive-analytical study, 168 elderly patients over 60 years were selected and studied using purposive sampling. The study tools include demographic, anxiety and self-efficacy questionnaires which filled in by the elderly patients in three stages: before surgery, at the time of discharged, and two months after the surgery. To achieve the objectives of the study, we used Pearson's correlation coefficient and regression analysis.

Result: The results revealed that there is a significant relationship between pre-operative self-efficacy with depression (p<0.01, r=-0.19) and vision-related quality of life (p<0.005, r=0.215) two months after the surgery. However pre-operative knowledge only has a significant relationship with depression at two months after surgery (p<0.005, r=0.213). According to the regression analysis, self-efficacy was identified as predictors of depression and vision-related quality of life after surgery. Meanwhile, knowledge predicts 4.6% of the changes in post-operative depression.

Conclusion: Based on the results, in designing training interventions, self-efficacy and knowledge need to be considered as the important predictors of patients’ psychological outcomes after surgery.
