Summary
A new scale, the Self-Efficacy Scale for Patients with Colorectal Cancer Surgery (SES-CRCS), has been developed and validated. This tool effectively measures self-efficacy in patients undergoing colorectal cancer surgery, aiding nursing care planning.
Area of Science:
- Nursing Science
- Oncology
- Psychometrics
Background:
- Self-efficacy is crucial for managing cancer surgery and informing nursing care.
- No validated tool exists to measure self-efficacy in colorectal cancer surgery patients.
Purpose of the Study:
- To develop and validate the Self-Efficacy Scale for Patients with Colorectal Cancer Surgery (SES-CRCS).
Main Methods:
- A multi-phase, cross-sectional study involving 170 patients.
- Scale development followed by validation including content validity, factor analysis (exploratory and confirmatory), and reliability testing (Cronbach's α, test-retest).
Main Results:
- Exploratory factor analysis revealed a 16-item single-factor structure with high factor loadings.
- The scale demonstrated good model fit, strong internal consistency (Cronbach's α = .838), and excellent test-retest reliability (r = .933).
Conclusions:
- The SES-CRCS is a valid and reliable instrument for assessing self-efficacy in patients undergoing colorectal cancer surgery.
- This scale can support personalized nursing care and improve patient outcomes.
