This study aimed to investigate the effect of a discharge training program structured according to the Roy adaptation model (RAM) on patient outcomes (quality of life, coping-adaptation, self-esteem) following gynecologic oncology surgery. This nonrandomized intervention studies consisted of two stages. In the first stage, patients were interviewed, patient needs after discharges were determined. Interview data were analyzed, and RAM-based training booklet was prepared. This booklet was prepared in line with a number of themes. In the second stage, the study was conducted with a sample of 36 control and 36 intervention patients, who were included in the discharge training program. Data was collected preoperatively, at 9(th) and 13(th) weeks after discharge. The mean quality of life and coping/adaptation scores of the intervention group at 13(th) weeks were significantly higher than those of the control group, however, no significant difference was found between the groups in terms of mean self-esteem scores.
