Objective:To analyzed effect of stratified positive psychological intervention based on Self-reporting Inventory (SCL-90) in patients with digestive tract tumors.Methods:Totally 78 patients with digestive tract cancer from January 2019 to February 2020 were divided into observation group (78 cases) and control group (76 cases), the control group given disease knowledge education, psychological intervention, diet and exercise management, and complication prevention etc routine nursing intervention, the observation group combined with stratified positive psychological intervention based on SCL-90 assessment strategy. Cancer-related fatigue, hope level and nurse satisfaction were compared between two groups.Results:6 months after intervention, the observation group cognitive fatigue, mental fatigue, physical fatigue, the influence of fatigue on life, cancer-related fatigue score were respectively (7.24±1.21), (7.58±1.16), (5.16±1.24), (7.65±1.42), (27.63±4.32) points. The control group were respectively (8.35±1.32), (8.02±1.12), (5.87±1.16), (8.72±1.56), (30.96±4.56) points. There were statistically significant of difference between the two groups ( t values were 2.265-5.442, P<0.05 or 0.01). Observation group Grade Ⅲ cancer-related fatigue total score were respectively (27.34±4.32), (27.65±4.25), (27.63±4.41) points, and the control group were respectively (29.56±5.12), (30.23±4.35), (40.77±5.45) points. There were statistically significant of difference between the two groups ( t values were 8.528, 2.163, 5.812, P<0.05 or 0.01). Observation group attitudes towards reality and the future, maintain close relationships with others, adopt positive action, hope level total score were respectively (10.35±2.01), (9.87±1.43), (10.16±1.42), (30.28±5.20) points, and control group were respectively (9.12±1.45), (9.15±1.32), (9.24±1.36), (27.51±4.36) points. There were statistically significant of difference between the two groups ( t values were 3.245-4.104, P<0.05 or 0.01). Observation group second and third grade hope level total score were respectively (30.24±5.20), (31.87±5.45) points, control group were respectively (27.24±4.23), (19.41±3.52) points. There were statistically significant of difference between the two groups ( t values were 2.271, 5.644, P<0.05 or 0.01). 6 months after intervention, The observation group nurse satisfaction 94.87% (74/78) higher than that control group 82.89% (63/76) ( χ2 value was 5.623, P=0.021) . Conclusion:Stratified positive psychological intervention based on SCL-90 assessment strategy help to ensure the balance of the intervention effect, alleviate cancer-related fatigue, Promote development of hope levels, and improve nurse satisfaction.
