A test should be invariant between relevant subgroups (e.g., demographic groups) within a larger population. [6] For example, for a test to be used in the United Kingdom, the test and its items should have approximately the same meaning for British males and females.
This initiative culminated in the creation of the Examination for Professional Practice in Psychology (EPPP) in 1965. The EPPP's initial adoption was gradual, but its acceptance steadily increased. By the mid-1980s, it had become the dominant entry-level examination for independent practice licensure in most jurisdictions across both countries.
The 2014 edition is the 7th edition of The Standards, and it shares the exact same names as the 1985 and 1999 editions. [3] Technical recommendations for psychological tests and diagnostic techniques: A preliminary proposal (1952) and Technical recommendations for psychological tests and diagnostic techniques (1954) editions were quite brief.
Measurement in psychology and physics are in no sense different. Physicists can measure when they can find the operations by which they may meet the necessary criteria; psychologists have to do the same. They need not worry about the mysterious differences between the meaning of measurement in the two sciences (Reese, 1943, p. 49). [9]
Classical test theory is an influential theory of test scores in the social sciences. In psychometrics, the theory has been superseded by the more sophisticated models in item response theory (IRT) and generalizability theory (G-theory).
Psychological evaluation is a method to assess an individual's behavior, personality, cognitive abilities, and several other domains. [a] [3] A common reason for a psychological evaluation is to identify psychological factors that may be inhibiting a person's ability to think, behave, or regulate emotion functionally or constructively.
Due to the fuzzy nature of constructs (concepts) in psychology, it is very difficult to use criterion-referenced approaches, such as those used in some parts of medicine (e.g. pregnancy tests). This is why construct validation is very important to personality test development.
(B) Test-Retest Reliability: Test-Retest Procedure is estimation of temporal consistency of the test. A test is administered twice to the same sample with a time interval. Correlation between two sets of scores is used as an estimate of reliability. Testing conditions are assumed to be identical.
