Abstract
This study aims to develop and validate a self-management scale for radiotherapy/chemotherapy-induced oral mucositis (SMS-RIOM/CIOM) in cancer survivors, addressing the need for a comprehensive tool to assess self-management capabilities. This study employed a two-phase process: (1) initial scale development through literature review, semi-structured interviews, and expert consultations, and (2) psychometric testing with 420 cancer survivors from five wards of Zibo Hospital. The psychometric evaluation included item analysis, content validity testing, reliability assessments, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). The finalized SMS-RIOM/CIOM consists of 15 items across four dimensions: medication management, oral pain management, disease monitoring, and daily life management. EFA explained 77.322% of the total variance, while CFA demonstrated an excellent model fit (χ²/df=1.909, RMSEA=0.064, RMR=0.052, GFI=0.911, CFI=0.964, NFI=0.928, TLI=0.955, IFI=0.964). Reliability metrics were robust, including Cronbach's alpha of 0.902, split-half reliability of 0.849, test-retest reliability of 0.862, and a scale content validity index of 0.910. The SMS-RIOM/CIOM is a reliable and valid tool for assessing self-management in cancer survivors with RIOM/CIOM. It provides valuable insights for clinical practice, enabling targeted interventions to improve self-management and enhance the quality of life for cancer survivors. Further research is recommended to validate its application across diverse populations and healthcare settings.
