Title : Development and evaluation of patient reported outcome scale for patients with urethral reconstruction after radical resection of lower urinary tract tumors
Abstract:
Objective:
- The aim of this study was to construct a set of scientifically available self- reported outcome scales for postoperative patients undergoing urethral reconstruction surgery after radical surgery for lower urinary tract tumors.
- The self-reported outcome scale, which mainly includes lifestyle and emotional state, was constructed, and the self-reported outcome scale was studied and evaluated for reliability and validity.
Methods: In this study, we reviewed the self-reported outcome scale and life situation of patients with urethral reconstruction after radical surgery for lower urinary tract tumors at home and abroad, and preliminarily determined the theoretical framework of the self-reported outcome scale for patients with urethral reconstruction after radical surgery for lower urinary tract tumors based on the Symptom Experience Model (SEM). The dimensions and item bank of the Self-Reported Outcome Scale for Patients with Urethral Reconstruction after Radical Surgery for Lower Urinary Tract Tumors were constructed. The Delphi expert consultation method, qualitative interviews on the nature of patient perceptions, and small-sample pre-surveys were used to assess and optimize the entries to form the first draft of the Self-Reported Outcome Scale for Patients with Urethral Reconstruction after Radical Surgery for Lower Urinary Tract Tumors.
Results: The initial self-reported outcome preliminary scale for patients with urethral reconstruction after radical surgery for lower urinary tract tumors initially constructed in this study contains 3 domains, 6 dimensions, and 44 entries.The overall Cronbach's alpha coefficient of the scale was 0.964, the overall re-test reliability of the scale was 0.982, and the split-half reliability coefficient was 0.930, which indicated that the scale in this study had good internal consistency and high reliability, and could be used for subsequent analytic studies. Through structural validity analysis, it was found that the scale entries could be interpreted as six factors explaining a total of 75.806% of the variance. Structural validity analyses of the three sub-domains of physiological, psychological, and situational were conducted separately, and it was found that the correlation coefficients between the factors ranged from 0.515 to 0.935 and were all statistically significant, with the entry-level content validity (I-CVI) ranging from 0.842 to 1, and the scale-level content validity (S-CVI) of 0.944, which indicates that the content validity of the scales is good. The final result was a formal version of the Lower Urinary Tract Reconstruction Patient Self-Report Outcome Scale containing 44 entries.
Conclusions: In this study, a variety of methods were used to develop a measurement tool applicable to the self-reported outcomes of patients with urethral reconstruction after radical surgery for lower urinary tract tumors, and the scale was assessed by a variety of measurement and evaluation methods to show that the scale has good content reliability, structural validity, and feasibility, and has the potential to be used for the evaluation of the health status of patients with urethral reconstruction after radical surgery for lower urinary tract tumors.
