The self-reported musculoskeletal functional limitations index appears to be a valid measure of musculoskeletal functional limitations, in the aspects of validity assessed in this study.
Table 2 summarizes the significant results across four aspects of validity for the three regions.
Moreover, there seems to be a lack of any acknowledgement for the evidence from the other aspects of validity in its modern sense.
Despite the plethora of investigations examining critical aspects of validity, caution is urged in the application of IMJTs in relation to measurement error and criterion validity.
In order to study its reliability and aspects of validity, data were collected and analysed consisting of a sample of 688 pre-service teachers in Flanders Belgiumm).
We undertook a content analysis of all studies using a hierarchical system of codes based on Aguinis, Pierce, Bosco, and Muslin's (2009) taxonomy of methodological choices across four aspects of validity (internal, external, construct, statistical conclusion).
To sum up, based on the examined quality measures (i)–(v) as well as on the considerations addressing the different aspects of validity concerning the instrument for measuring CCER, a successful test construction can be assumed.
In this follow-up study, we compare the methodological choices of studies undertaken in North America (n = 66), Europe (n = 95) and Asia (n = 80, including 57 from China)3 across four aspects of validity: internal, external, construct and statistical conclusion validity.
When a test is being validated using (Messick 1989a) validity framework, however, the evidence from correlation will form only a small part of the required validity evidence to be complemented by evidence from other aspects of validity mentioned earlier in the introduction.
For example, if the constructs used to represent the cause and effect are problematic in terms of their definitions and measurements, this will have consequences for all other aspects of validity and will seriously affect the validity of the causal claims.
For a test to be regarded as a valid measure and to produce meaningful scores with interpretations and actions that are adequate and appropriate, apart from such external evidence, support should also be provided from many other internal aspects of validity unable to be taken care of by correlation coefficients.
