A critical analysis of test-retest reliability in instrument validation studies of cancer patients under palliative care: a systematic review

Abstract: BackgroundPatient-reported outcome validation needs to achieve validity and reliability standards. Among reliability analysis parameters, test-retest reliability is an important psychometric property. Retested patients must be in a clinically stable condition. This is particularly problematic in palliative care (PC) settings because advanced cancer patients are prone to a faster rate of clinical deterioration. The aim of this study was to evaluate the methods by which multi-symptom and health-related qualities… Show more

“…The 59 students who were present at both of the administrations were included in the analyses. This sample size (i.e., n = 59) is bigger than that used by Buhrmester et al (1988) to evaluate the test-retest reliability of the ICQ (n = 31) in their original article, and it is consistent with current recommendations (e.g., Hertzog, 2008;Walter, Eliasziw, & Donner, 1998) and practice (e.g., Calamia, Markon, & Tranel, 2013;Paiva et al, 2014) in psychology and medicine. Age ranged from 19 to 34 years (M = 22.5; SD = 2.1), most of them (49, i.e., 83.1%)…”

“…The acceptable minimum point for test-retest reliability is 0.70 according to previous literature. 28 The Zarit Burden score was highly correlated with the CBI score (Pearson's correlation coefficient, r=0.909, p=0.001).…”

“…Following unfavorable findings in the systematic reviews [5,6], a recent call for higher standards of conducting and reporting test-retest study was made [7][8][9]. This study investigates for the first time the test-retest reliability of the HeartQoL (original English version) in accordance with guidelines from the COnsensus-based Standards for the selection of health status Measurement Instruments (COS-MIN) [8,10] and Guideline for Reporting Reliability and Agreement Studies (GRRAS) [7].…”
