Performance of depression rating scales in patients with chronic kidney disease: an item response theory-based analysis.

ABSTRACT:

Objective

Because there is overlap between somatic symptoms of depression and symptoms of chronic kidney disease (CKD), it is unclear if self-reported depression rating scales can be used accurately in predialysis CKD patients, especially if CKD and other comorbidities are symptomatic. We assessed the performance of two depression scales - the Beck Depression Inventory (BDI) and the Quick Inventory of Depression Symptomatology (QIDS-SR16) - by CKD stage, diagnosis of diabetes and total medical comorbidity burden - using item response theory (IRT) in a sample of 272 predialysis CKD patients.

Methods

We performed IRT by low versus high CKD stage, diabetes versus no diabetes and high (>3 diagnoses) versus low medical comorbidity burden.

Results

IRT models of each rating
