In the February 2016 issue (Vol. 27, No. 2), in the article “On Diagnostic Accuracy in Audiology: Central Site of Lesion and Central Auditory Processing
Disorder Studies” by Vermiglio, the author identified errors in the text. The correct text is presented
in italics.
Corrections for Table 6 on page 148
-
1) Olsen et al (1975) study, True Positives = 41.7%.
-
2) Musiek and Pinheiro (1987), False Negatives = 33.3%, True Positives = 66.7, False Positives, True Negatives, and Efficiency were not reported.
-
3) For the Musiek et al (2011) study, the correct labels for the index test(s), in
order, are Dichotic digits, Competing sentences, Frequency patterns and Filtered speech.
Corrections for Table 8 on page 153
-
1) The correct values for the first row are 25.0, 23.9, 76.1, 75.0, and 75.8.
-
2) The correct values for the second row are 21.7, 13.6, 86.4, 78.3, and 82.2.
Text correction starting with the last sentence on page 146 (continues on page 148)
The true-positive values (sensitivity) range from 41.7% for the speech recognition in quiet and in noise protocol used in the study by Olsen
et al (1975) to 100% for the duration pattern and gaps-in-noise tests used by Bamiou
et al (2006). The true-negative values (specificity) range from 72.4% for the filtered speech test from the Musiek et al (2011) study to 100% for dichotic digits test (DDT), frequency
pattern, duration pattern, and gaps-in-noise tests used in the study by Bamiou et
al (2006) and for the competing sentences test in the study by Musiek et al (2011). It should be noted that the number of patients
and control participants for the Bamiou et al (2006) study was only eight for each
group. The Musiek et al (2011) study on the other hand had 20 participants each in
the patient and control groups. Test efficiency (percentage of correct results) ranged
from 63.3% for the filtered speech test (Musiek et al, 2011) to 100% for the duration pattern and gaps-in-noise tests
used in the study by Bamiou et al (2006).
Text correction, p. 152, right column, starting with the third sentence in the first
full paragraph
Table 8 shows that the diagnostic accuracy values of the psychoacoustic pattern discrimination test for a lesion of the CANS are not the same as the values
for a “central hearing disorder.” For example, the specificity of the index test for
lesions of the CANS was 75.0% and for a “central hearing disorder” the specificity was 78.3%. The false negatives found for a lesion of the CANS was 23.9% and 13.6% for the “central hearing disorder.”
