Abstract:
Objective:To develop the Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy and evaluate its reliability and validity.Methods:Based on the theory of unpleasant symptoms, a preliminary version of the Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy was developed through literature analysis, semi-structured interviews, and the Delphi method. After revising certain items in the pre-survey, convenience sampling was used to select patients who underwent bladder instillation chemotherapy in the Department of Urology Surgery of three ClassⅢ Grade A hospitals in Yunnan Province from January to July 2024 as research subjects to test the reliability and validity of the scale.Results:A total of 168 questionnaires were distributed, and 162 valid questionnaires were collected, with a valid response rate of 96.429% (162/168). The Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy covered two areas of symptom severity and symptom distress, comprising five dimensions and 27 items. The Cronbach's α coefficient for the total scale was 0.953, and the split-half reliability coefficient was 0.806. Exploratory factor analysis revealed that the four common factors for symptom severity contributed to 73.196% of the cumulative variance, while the single common factor for symptom distress accounted for 68.285% of the cumulative variance. Confirmatory factor analysis revealed that all indicators met the fit criteria, indicating that the model possessed good goodness-of-fit. The content validity index at the scale level was 0.940, while the content validity index at the item level ranged from 0.833 to 1.000.Conclusions:The Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy developed in this study demonstrates good reliability and validity, and is suitable for evaluating symptoms in patients undergoing bladder infusion chemotherapy.
