The CKDSI-Sri Lanka is a valid and reliable instrument for assessing symptom burden in patients with chronic kidney disease in Sri Lanka.
Senanayake et al. (2017) conducted a cross-sectional in Chronic Kidney Disease (n=250). Chronic Kidney Disease Symptom Index - Sri Lanka was evaluated on Median symptom burden score in patients with vs without comorbidities (discriminant validity) (p=<0.001). The Chronic Kidney Disease Symptom Index - Sri Lanka demonstrated strong psychometric properties, including high test-retest reliability (r > 0.9) and significant convergent validity.
