Summary
A new scale assesses cancer patients
Area of Science:
- Oncology
- Health Psychology
- Medical Sociology
Background:
- Cancer treatment decisions are complex and require patient involvement.
- Understanding patients' needs is crucial for effective decision support.
- Existing scales may not adequately capture the specific needs of Chinese cancer patients.
Purpose of the Study:
- To construct and validate a Treatment Decision-making Needs Assessment Scale for cancer patients in China.
- To provide a culturally relevant tool for assessing decisional needs.
- To enhance shared decision-making in cancer care.
Main Methods:
- Literature review and expert correspondence to develop an item pool.
- Exploratory and confirmatory factor analysis (EFA/CFA) for scale construction.
- Reliability and validity testing with 407 Chinese cancer patients.
Main Results:
- The scale comprises three dimensions: Decision-making cognition, Disease knowledge, and Support and resource acquisition, with 15 items.
- High reliability (Cronbach's α = 0.833, test-retest = 0.856) and content validity (CVI = 0.906).
- EFA extracted three factors explaining 66.82% of variance; CFA confirmed adequate model fit.
Conclusions:
- The developed scale demonstrates acceptable reliability and validity.
- It is a potentially useful tool for assessing treatment-related decisional needs in Chinese cancer patients.
- The scale can inform clinical practice and future research on shared decision-making.
