A Comparison of Self-report and Clinical Diagnostic Interviews for Depression

Abstract

Weak agreement at the level of diagnosis continues to threaten the credibility of estimates of prevalence of specific disorders. A bias toward underreporting, as well as stronger agreement at the level of the depression syndrome and on ordinal measures of depressive symptoms, suggests that associations with risk factors are conservative.

Cohen’s quadratically weighted kappa is higher than linearly weighted kappa for tridiagonal agreement tables

“…Agreement tables that are tridiagonal or approximately tridiagonal are frequently observed in Table 1: Ratings of 100 patients by pairs of observers on the degree of disability on a 6-category scale [15]. Column totals 6 10 21 16 22 25 100 applications with ordered categories [3,7,8,14]. The paper is organized as follows.…”

Listado de síntomas breve (short checklist of symptoms) in Argentinean adults: psychometric study of its main clinical scales

“…Thus, as the main objective of screening test of psychopathology is to detect individuals at risk from the general population, the idea of using a sample of those characteristics presents as a judicious strategy (Eaton, Neufeld, Chen, & Cai, 2000).…”

“…The exclusion of both Paranoid Ideation and Psychoticism scales was among the main changes introduced. In this respect, Eaton et al (2000) remarked that self-report measures are not suitable for assessing psychotic disorders. Moreover, de Rivera and Abuín (2012) stated that these aspects should not be included in self-report tests, as they comprise items with unclear content.…”

Weighted kappa is higher than Cohen’s kappa for tridiagonal agreement tables

“…Agreement tables that are tridiagonal or approximately tridiagonal are frequently encountered in applications. Examples can be found in Van Swieten et al (1987), Seddon et al (1990) Eaton et al (2000), Cai et al (2002) and Dirksen et al (2002).…”
