To explore the application effect of the adaptive-system dual-model psychological nursing based on Rosenthal effect theory for elderly patients undergoing colorectal cancer surgery.

A total of 96 elderly patients with colorectal cancer who were admitted to the Third People's Hospital of Bengbu City,Anhui Province from July 2022 to April 2025 were selected.Among them,48 patients admitted from July 2022 to January 2024 were assigned to the control group,and 48 patients admitted from February 2024 to April 2025 were assigned to the study group.The patients in control group received routine nursing.The patients in study group implemented the adaptation-system dual-model psychological nursing based on Rosenthal effect theory on the basis of routine nursing.The perioperative related indicators and hospital stay of the two groups were compared.The psychological state,coping style,level of perceived social support,hope level and nursing satisfaction of the two groups before intervention and at discharge were also compared.

The recovery time of bowel sounds,the time of first defecation,the time of getting out of bed for activities,and the length of hospital stay in the study group were all shorter than those in the control group(P<0.05).At discharge,the scores of the Psychosocial Adjustment to Illness Scale-Self Report(PAIS-SR), the Self-Rating Depression Scale(SDS), the Self-Rating Anxiety Scale(SAS),and the negative coping score decreased in both groups,and the study group had lower scores than the control group(P<0.05).At discharge,the total scores of the Life Orientation Test-Revised(LOT-R), the positive coping, Perceived Social Support Scale(PSSS), and the Herth Hope Inventory(HHI) increased in both groups,and the study group had higher scores than the control group(P<0.05).The nursing satisfaction rate of the study group was higher than that of the control group(P<0.05).

The adaptation-system dual-model psychological nursing based on Rosenthal effect theory in elderly patients undergoing colorectal cancer surgery could improve the psychological state and coping strategies of elderly patients undergoing colorectal cancer surgery,enhance their perception of social support and hope levels,promote postoperative recovery,shorten hospital stay,and increase nursing satisfaction.
