07 Aug Response to Another Student Discussion #2
There are two different views of the validation process and they are the unitarian and the trinitarian views. (Guinon, 1980). The unitarian view has one type of validity which is the construct as oppose to the trinitairan view that has three: content, criterion-related and construct. The unitarian view of validity only measures what a test claims to measure. It does not measure or take into account what a cohesive construct validation should and that includes content and criterion-related evidence. (Messick, 1995).
Advantages and Disadvantages
In the trinitarian view, there is a process of validity content, criterion-related and construct and neither of these areas can be stand alone as it is part of entire process that produces a more thorough end result of a hypothesis testing. (Guinon, 1980) The disadvantage of this process would be that is much more time consuming than the unitarian view as it requires more testing to set a standards. The unitarian view is less time consuming as it is only testing what it is intended to test and takes into account both test performance and relationships with variables that can affect the score but it is far less reliable because there are no set standards for the test. (Messick, 1995)
Most Valid Form of Validity and Thoughts
In addition to the unitarian view, the trinitarian view includes two other processes for validation which are content and criterion-related validity. This model allows a correct set standards or predictions (criterion-related validity). (Cohen, 2007) It questions if the measuring tool is appropriated for the behavior that it is intended to measure (content validity). Finally, it questions if it measured what it was supposed to measure (construct validity). All in all, the trinitarian view allows for a more reliable measurement.
