Abstract
A method for developing and validating a quality assessment for a test is provided. A test method is also provided, which assesses the accuracy of a test. The methods include performing a behavioral test on a subject to measure a psychometric quantity, measuring one or more quality indicators, the quality indicators being any variables that are correlated with test accuracy, obtaining an independent measure of test accuracy, and deriving a predictive formula for estimating test accuracy from the quality indicators.
Claims45
A method for developing a quality assessment for a test, comprising:
- performing a behavioral test on a subject to measure a psychometric quantity;
- measuring the psychometric quantity to provide a test measurement of the psychometric quantity;
- measuring one or more quality indicators to provide one or more quality indicator measurements, the quality indicator being any variable that gives an indication of test accuracy;
- obtaining an independent measurement of the psychometric quantity for the subject;
- calculating a difference between the test measurement and the independent measurement;
- determining a relationship between the quality indicator measurements and the difference between the test measurement and the independent measurement;
- and
- using the relationship to predict a difference between the test result and the independent measure of the psychometric quantity, the difference being a quantitative measure of test accuracy.
A test method, comprising:
- performing a behavioral test on a subject to measure a psychometric quantity;
- measuring the psychometric quantity to provide a test measurement of the psychometric quantity;
- measuring one or more quality indicators to provide one or more quality indicator measurements, the quality indicator being any variable that gives an indication of test accuracy;
- and
- calculating an estimated test accuracy using the one or more quality indicator measurements.
A hearing test method, comprising:
- performing a hearing test on a subject to measure the subject's hearing;
- measuring at least one quality indicator to provide a quality indicator measurement, the quality indicator being any variable that gives an indication of reliability of the hearing test;
- and
- calculating an estimated test accuracy using the one or more quality indicator measurements.
A method for testing hearing of a subject, the method comprising:
- performing an automated hearing test;
- and
- tracking quality indicators during the hearing test, wherein the quality indicators include a masker alert rate, time per trial, average number of trials for a threshold, total elapsed time, false alarm rate, average test-retest difference, quality check fail rate, air-bone gap >50 dB and air-bone gap <−10 dB.
