Normative Sample: Validity (define)
Quality of test interpretation or use. Validity depends on how well-funded, trustworthy, and reliable the resource is.
Content Validity (define)
Items on the test tells if a child has a disorder.
Construct Validity (define)
The ability of the test to tell if a child has a disorder.
-how well does the test measure what it was intended to measure?
Discriminant Accuracy (define)
How accurate does a test need to be in distinguishing a language disorder?
The Vance and Plante Standard
-90% accuracy or better is good
-80%-89% accuracy is fair
-below 80% is unacceptable
Reference Standard
Definition of who has a language disorder, who doesn’t, and/or who receives services.
Intra-reliability
Is the test outcome the same when administered by the evaluator?
Reliability and Validity: Standard Error of Measurement
Any reported test scores must be given through a confidence interval
Specificity
The specificity of a test is its ability to designate an individual who does not have a disease as negative.
Sensitivity
Sensitivity refers to a test’s ability to designate an individual with disease as positive.
Criterion/concurrent validity
Concurrent validity measures how a new test compares against a validated test, called the criterion or “gold standard.”
Inter-rater reliability
Inter-rater reliability (IRR) refers to the reproducibility or consistency of decisions between two reviewers and is a necessary component of validity
Test-retest reliability
Test-retest reliability is a statistical measure commonly used to assess the consistency and reproducibility of results obtained from healthy controls in research studies.
Confidence Interval
A confidence interval refers to the probability that a population parameter will fall between a set of values for a certain proportion of times.
