The Bornstein PF Model And Traditional Model Of Validity

This paper discusses the Bornstein PF model and traditional model of validity. It discusses how Bornstein maintains that it is important to use the PF model of validity. It discusses the tools used to group categories of mental activities and behaviors when responding to test. Furthermore, it discusses how Bornstein’s PF model could assess with validity in assessment of children with autism and difficulties with social functioning.

Validity is how well a test or measurement tool measures what it purports to measure. Traditionally validity is conceptualized into three categories content validity, construct validity, and criterion-related validity (Cohen, 2013). Content validity measures the validity based on an evaluation

The traditional approach correlational methods are used to quantify the association among test score and criterion. The PF model differs from traditional validity assessment not only with respect to how validity is conceptualized but also with respect to empirical emphasis. The PF model switches emphasis of validity theory and research from outcome to process and from correlation to experimentation. A process-driven approach and traditional validity assessment can enhance assessment procedures in the psychology field. This can enhance researchers’ knowledge of test score misuse by enlightening the fundamental intra-an interpersonal dynamics that guide to differential performance (and differential prediction) in different groups (Bornstein,…show more content…
This model conceptualizes validity to a level in which respondents are able to connect in expected psychological process during testing; once the processes are identified, experimental manipulations are introduced to alter these processes and determine whether the manipulations are introduced to alter theses processes and determine whether the manipulations affect test scores in meaningful ways. The PF framework reverses the usual procedure for dealing with extraneous variables that alter psychological test scores: Instead of viewing them as problematic, the PF model conceptualizes variables that are seen as confounds in traditional validity assessment (e.g., self-presentation effects) as opportunities for manipulation, exploration, and focused analysis windows on underlying process that would otherwise remain hidden. Psychological activities in which people engage when responding to psychological tests are determined by the nature of the instruments themselves by the types of questions asked and the task by the nature of the instruments themselves by the types of questions asked and the tasks and activities required of the respondent (Bornstein,
