Abstract: Objective To investigate the effect of narrative therapy in patients with postoperative colostomy for colorectal cancer. Methods A total of 80 patients with postoperative colostomy for colorectal cancer treated in our hospital from January 2019 to January 2024 were selected and divided into observation group (40) and control group (40) by random number table method. The control group was given routine intervention, and the observation group was given narrative therapy on the basis of the control group. Negative emotion, coping style and social psychological adaptation level were compared between the two groups. Results Before intervention, there was no significant difference in Beck Anxiety Inventory(BAI) score and Beck Depression Inventory-Ⅱ (BDI-Ⅱ) scores between the two groups (P>0.05). After intervention, the BAI score and BDI-Ⅱ score of the two groups were lower than before intervention, and the observation group was lower than the control group, the difference was statistically significant (P<0.05). Before intervention, there was no difference in positive coping score and negative coping score between the two groups (P>0.05). After intervention, the positive coping scores of both groups were higher than before intervention, and the observation group was higher than the control group, the difference was statistically significant (P<0.05). After intervention, the negative coping scores of both groups were lower than before intervention, and the observation group was lower than the control group, the difference was statistically significant (P<0.05). Before intervention, there was no significant difference in OAI-20 scores between the two groups (P>0.05). After intervention, the Ostomy Adjustment Inventory-20 (OAI-20) scores of both groups were higher than before intervention, and the observation group was higher than the control group, with statistical significance (P<0.05). Conclusion The application of narrative therapy in the intervention of postoperative colostomy patients with colorectal cancer can reduce negative emotions, improve the level of social psychological adaptation, and promote the improvement of coping style.
