Test-retest reliability
The degree to which a test yields the same results when it is given more than once to the same person
Evaluated by correlating a person’s score on the same test at two different time points.
Alternate-form reliability
A method where two versions of the same test are designed and scores from each are correlated with one another.
Internal consistency
Refers to the degree of reliability within a test
Split-half reliability
is a method that compares responses on odd numbers to responses on even numbers.
Coefficient alpha
Calculated by averaging the intercorrelations of all items within a test.
Face validity
user of a test believes that the items on that test resemble the characteristics associated with the concept being tested.
Content validity
Requires that the test’s items reflect all behaviours believed to be related to the overall construct.
Criterion validity
Correlation between a measure & a criterion
Construct validity
refers to the importance of a test within a specific theoretical framework and can only be understood in the context of that framework.
Clinical Approach
An approach to evaluating and interpreting the data on patients, making predictions, and coming to decisions that relies on the clinician’s experience and personal judgment, guided by intuition honed with professional experience rather than by formal rules.
Actuarial Approach
An approach to evaluating and interpreting the data on patients, making predictions, and coming to decisions that relies exclusively on statistical procedures, empirical methods, and formal rules.
