Abstract
Purpose
Patients affected by tuberculosis have diverse unmet supportive care needs (SCN) that may seriously affect their treatment adherence. Accurately assessing patients’ SCN is important for providing efficient patient-centred care, but few instruments are suitable for use in clinical practice. Therefore, the purpose of this study was to develop an SCN scale for patients with tuberculosis (SCN-TB) and to evaluate its psychometrical properties.
Patients and Methods
Based on the SCN framework, the SCN-TB was designed via a literature review, Delphi consultation and pilot study. Then, 550 patients from four tuberculosis specialist hospitals in Shaanxi Province were enrolled by convenience sampling to further test the validity and reliability of the SCN-TB.
Results
A total of 518 patients completed the survey. The final scale encompasses 25 items in five domains: physical, practical, psycho-emotional, social, and informational. The content validity for the scale was 0.93, with that for each item ranging from 0.80 to 1.00. Five factors that explained 80.38% of the variance were identified in exploratory factor analysis. A five-factor model was then confirmed with confirmatory factor analysis using maximum likelihood estimation with bootstrapping. The model fit indices were χ2/df=1.062 (Bollen-Stine χ2=281.382, df=265, p<0.001), CFI=0.997, RMSEA=0.016, SRMR=0.053, NFI=0.951, and GFI=0.929. All factors had acceptable convergent and discriminant validity. The Cronbach’s α, split-half, and test-retest reliability coefficients of the scale were 0.884, 0.883, and 0.854, respectively.
Conclusion
The SCN-TB is a valid and reliable theory based tool for assessing the needs of patients with tuberculosis and can be applied in both clinical practice and research.
