In psychometrics, predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure. [1] [2]For example, the validity of a cognitive test for job performance is the correlation between test scores and, for example, supervisor performance ratings.
It is difficult to develop an animal model that perfectly reproduces the symptoms of depression in patients. It is generic that 3 standards may be used to evaluate the reliability of an animal version of depression: the phenomenological or morphological appearances (face validity), a comparable etiology (assemble validity), and healing similarities (predictive validity).
The Standards for Educational and Psychological Measurement gives the following statement on test validity: "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [36] Simply put, a test is not valid unless it is used and interpreted in the way it is intended. [37]
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
The predictive validity of g is greater than that of work experience, and increased experience on the job does not decrease the validity of g. [64] [75] In a 2011 meta-analysis, researchers found that general cognitive ability (GCA) predicted job performance better than personality (Five factor model) and three streams of emotional intelligence.
When there is a mismatch in these models developed across these swapped training and validation samples as happens quite frequently, MAQC-II shows that this will be much more predictive of poor external predictive validity than traditional cross-validation.
Although concurrent and predictive validity are similar, it is cautioned to keep the terms and findings separated. "Concurrent validity should not be used as a substitute for predictive validity without an appropriate supporting rationale." [3] Criterion validity is typically assessed by comparison with a gold standard test. [4]
