According to the National Institute for Mental Health, nearly 10% of Americans have mood problems, and those with End Stage Renal Disease (ESRD) are twice as likely to have symptoms of depression. In individuals who have received a kidney transplant, and those awaiting one, depression directly affects mortality because it influences a client’s outlook, disposition and adherence to treatment. Therefore, determining who is at increased risk for depression among this group of people is critically important. In an attempt to identify which scale is most effective for measuring depression in clients with ESRD, researchers at Simon Fraser University and the University of British Columbia assessed 455 clients, with and without ESRD, using the Beck Depression Inventory –II (BDI-II) and the Center for Epidemiologic Studies Depression Scale (CES-D).
Although the BDI-II is reliable for identifying depressive symptoms in the general population, the team theorized that the CES-D would be a more accurate tool for people with ESRD. “The CES–D differs from this and other self-report measures of depression, in that it specifically examines symptoms separately within four distinct domains (Depressive Affect, Absence of Well-Being, Somatic Symptoms, and Interpersonal Affect),” said Theone S. E. Paterson of Simon Fraser University and lead author of the study. “This differentiation between four symptom domains offered by the CES–D incorporates the ability to explore the presence or absence of positive affect and interpersonal symptoms, which may allow for a more comprehensive, although still brief and easily manageable, assessment of depression in this patient population.”
The researchers found that the measures provided in the CES-D isolated specific symptoms of depression more accurately than the BDI-II, particularly in the second-order depression symptoms. “Specifically, this information may be important in the characterization of depression among these patients.” The team added, “Use of the CES-D will not only save clinicians (and patients) time in assessment but will also ensure that important aspects of depression are assessed, likely increasing accuracy of diagnosis and subsequent treatment.”
