It can gradually progress from low emotion to grief-stricken, negative pessimistic, and extreme thoughts such as suicide which may occur in severe cases. Depression is a kind of bad psychology characterized by low spirit, slow thinking, and decreased willpower activity. Anxiety is a form of psychological stress protection mechanism generated by patientsвЂ™ excessive worry in the case of emergency or expected adverse outcomes, which can cause irritability, panic, and other emotions and result in inattention and memory reduction. In recent years, with the continuous improvement of the social level, the survival time of tumor patients has been prolonged, and the psychological status of patients has gradually become the focus of clinical observation.Дiagnosis informing is a strong psychological shock, which can cause a variety of emotional disorders and psychological problems, resulting in endocrine disorders and metabolic and immune dysfunction and affecting the disease progression, treatment, recovery, and outcome of patients. At present, surgery, chemotherapy, radiotherapy, and traditional Chinese medicine therapy are common clinical tumor treatments, which have a certain effect on patients with gastrointestinal tumors and can improve the prognosis of patients. There is no obvious manifestation in the initial stage of the disease, but with the progress of the disease, symptoms such as abdominal pain, hematemesis, melena, and intestinal obstruction may appear and even lead to multiple organ failure, which is life-threatening and has a great impact on the quality of life of patients. It has the characteristics of rapid progress and high mortality rate and has become a frequent clinical disease. Thus, the Zung SDS is a non-diagnostically specific indicator of depressive symptomatology.Gastrointestinal tumor is a tumor occurring in the stomach and intestine, mainly including gastrointestinal adenoma, fibroma, gastric cancer, and colorectal cancer. Guy (1976) found that mean total scores for five diagnostic groups were as follows:Д¤8 for transient situational disorder (i.e., adjustment disorder) (n = 12), The 4-factor structure was validated and high coefficients of congruence were obtained (0.98, 0.95, 0.92 and 0.87 for factors I, II, III and IV, respectively). Romera et al., (2008) examine the symptomatic dimensions of depression in 1049 patients with major depressive disorder (MDD) in the primary care setting by means of a factor analysis, finding four factors: core depressive factor cognitive factor an anxiety factor and a somatic factor. Thus, Zung SDS scores discriminated depressed from non-depressed samples. Zung (1965) reported a range of Zung SDS index scores from 0.63 to 0.90 with a mean of 0.74 (total score equivalent of 59) in depressed outpatients, whereas hospital staff control subjects showed a range of 0.25-0.43 with a mean of 0.33 (total score equivalent of 26). In a community survey of 1,173 subjects, CronbachвЂ™s alpha was satisfactory at 0.79 (Knight et al., 1983). Split-half reliability studies in a psychiatric population found a correlation (r) of 0.73 (Zung, 1972). Scores were inversely correlated with age, indicating the importance of specific and appropriate norms in assessing affective states. High estimates of reliability based on internal consistency statistics were found, with females scoring higher. Knight, Waal-Manning, Hendrika and Spears (1983) validated the Zung Self-Rating Depression Scale with 2,120 New Zealanders between 16 and 89 years of age.
