What is an acceptable validity coefficient?

As a general rule, the higher the validity coefficient the more beneficial it is to use the test. Validity coefficients of r =. 21 to r =. 35 are typical for a single test.

Which type of validity coefficient is most important for personality tests?

Criterion validity is one of the most powerful ways to provide the validity of personality tests. Criterion validity measures how well a test correlates with an outcome. There are two types of criterion validity, and these are concurrent validity and predictive validity.

What is a good construct validity score?

A number close to 1 indicates very high construct validity. Any number less than 0.5 indicates limited construct validity. Negative values showing that an assessment has very low construct validity – this would suggest that the assessment is not a good way to measure the intended construct at all.

What is a good correlation for criterion validity?

We typically measure criterion validity using a metric like the Pearson Correlation Coefficient, which takes on value between -1 and 1 where: -1 indicates a perfectly negative linear correlation between two variables. 0 indicates no linear correlation between two variables.
