Correlate your scales with a wide range of other variables. The five factors of the original ZKPQ were well replicated, and the factor structure (principal axis plus varimax rotation) was shown to be highly congruent in the three samples despite cultural and age differences between the samples. The questionnaire must include only relevant questions that measure known indicators of depression. The consequential aspect of construct validity includes evidence for evaluating the intended and unintended consequences of score interpretation and use. In other words, individuals who score high on the test tend to perform better on the job than those who score low on the test. Charles S. Reichardt, in Encyclopedia of Social Measurement, 2005. This view was confirmed in laboratory animals, in which it was shown that deletion of one specific gene leads to an increase or decrease in cocaine-using behavior and/or cocaine-seeking vulnerability. Factor intercorrelations indicate a relative orthogonality among the five factors, with two exceptions. This finding indicates that a history of chronic cocaine use leads to a hypofunction of HPA activity and to an altered reactivity to stress. For example, imagine that you were interested in developing a Item-item questionnaire that significantly correlated with total score indicates that the items are valid. For instance, acute cocaine administration increases plasma levels of Adrenocorticotropic hormone (ACTH) and glucocorticoids in humans. The issue of generalizability of score inferences across tasks or contexts links to the score meaningfulness. For example, knocking out genes that regulate receptor or neurotransmitter functions linked to DA, glutamate, serotonin, and endocannabinoidergic has been shown to dramatically change the sensitivity to cocaine and/or the motivation to its consumption. 2. Such evidence can be derived through various sources, such as “thinking aloud” protocols and eye-movement records, during responding or through computer modeling of task processes. test is a work sample, the behavior represented in the test may be an end in itself. The CTCM model consisted of four correlated language constructs and … Thus, you can infer that he is experiencing exam stress, which is an example of a construc… Consequences can be associated with bias in scoring and interpretation or with unfairness in test employment. Construct Validity Example: There are many possible examples of construct validity. The goal of the test developed is to ensure that important aspects of the construct domain are covered. Evidence of generalizability relies on the degree of correlation of the assessed tasks with other tasks representing the construct or aspects of the construct. Discriminant validity and convergent validity are the two components of construct validity. Don’t confuse this type of validity (often called test validity) with experimental validity, which is composed of internal and external validity. If a research project scores highly in these areas, then the overall test validity is high. For example, one way to demonstrate the construct validity of a cognitive aptitude test is by correlating the outcomes on the test to those found on other widely accepted measures of cognitive aptitude. From: International Encyclopedia of Public Health, 2008, A. Fink, in International Encyclopedia of Education (Third Edition), 2010. Additional evidence supporting the construct validity of animal models comes from studies of two inbred rat lines, the Lewis (LEW) and its histocompatible control, the Fischer 344 strain (F344). Hence, the more strategies used to demonstrate the validity of a test, the more confidence test users have in the construct validity of that test, but only if the evidence provided by those strategies is convincing.
