Abstract
Purpose
Identifying the palliative care needs of patients with advanced cancer is important for maintaining quality of life and timely transition to palliative care. We aimed to validate the Korean Sheffield Profile for Assessment and Referral for Care (K-SPARC) in such patients and establish its psychometric properties, including reliability, validity, and responsiveness to change.
Materials and Methods
We used the forward-back translated version of SPARC, which was verified through a pilot study, to assess the palliative care needs of patients with advanced cancer. Reliability was evaluated by internal consistency using Cronbach's alpha coefficients and test-retest reliability. Criterion validity was analyzed against other questionnaires, including the Korean versions of the Functional Assessment of Cancer Therapy-General (FACT-G Korean) and Korean versions of the Edmonton Symptom Assessment System (K-ESAS). Factor analysis was used to assess construct validity.
Results
Two hundred fifty-nine patients were included from 2019 to 2022. Forty-nine percent of all patients were women, and the median age was 63 years. Cronbach’s alpha coefficient (range, 0.642–0.903) and test-retest reliability (range, 0.574–0.749) indicated acceptable reliability. The correlation coefficients between K-SPARC and FACT-G Korean suggested significant criterion validity. The correlation coefficients for the physical, social, emotional, and functional domains were 0.701, 0.249, 0.718, and 0.511, respectively (p-value <0.001, all). Factor analysis demonstrated satisfactory construct validity of the tool.
Conclusion
This study demonstrated the utility of K-SPARC as an evaluation tool for providing palliative care to patients with advanced cancer through psychometric validation; the tool had good internal consistency, reliability, and acceptable validity.
