Abstract
A critique of Hankins, M: How discriminating are discriminative instruments?" Health and Quality of Life Outcomes 2008, 6:36
Highlights
Did this paper trigger a reflection on the psychometric masters of the mid 20th century, it caused me to contemplate the debt of gratitude I and other health outcomes researchers have to the late 20th and 21st century health researchers at McMaster University who have taken the knowledge written and stored in the bowels of the Lewis Annex to applications featured in the center of all brightly-lit health science libraries, and, informing and changing the practice of health care
In order to make a case for the needed usefulness of Ferguson's Delta, Hankins has not embraced the purpose or details of the Kirshner and Guyatt's 1985 taxonomy paper, or the relevant work by these authors beyond 1992
The bibliography in Hankins' paper leads me to fear that he has missed the rich Evidence-Based Medicine series published in JAMA and other insightful theoretical and clinical applications for the measurement and evaluation of HRQOL measures that have emerged over the past 3+ decades among McMaster heath science researchers
Summary
In order to make a case for the needed usefulness of Ferguson's Delta, Hankins has not embraced the purpose or details of the Kirshner and Guyatt's 1985 taxonomy paper, or the relevant work by these authors beyond 1992. As I read Matthew Hankins' paper on the use of Ferguson's Delta [1] as an index of discriminate validity, the smell and fond memories of the Lewis Annex swept over me like a soft cloud.
