Abstract: A diagnostic accuracy study is used to determine the ability of a test to correctly identify the presence and absence of a target disorder. A diagnostic system, including an index test, target disorder, and a reference standard test is required for this type of investigation. According to Bossuyt et al (2003), this process has been poorly understood in many fields of study including medicine. The purpose of this presentation is to provide a critical review of descriptions of diagnostic accuracy for measures of functional hearing provided by the World Health Organization and National Academies of Sciences, Engineering, and Medicine.

Learning Objectives:

Describe the three major components of a diagnostic system.
Identify the limitations of the National Academies of Science, Engineering, and Medicine report on the diagnostic evidence for speech recognition in noise assessments.
Describe the diagnostic accuracy of the better ear pure-tone average, as used by the World Health Organization, to infer speech recognition in noise ability.
