Participants in a sample may not be representative of the population of interest. Convergent validity refers to how closely the new scale is related to other variables and other measures of the same construct. The primary validity scales inherent to the MMPI include the F scale (endorsement of unusual symptoms), L scale (endorsement of socially laudable, but unusual traits), and K scale (defensiveness).

In practice, we often measure face validity by asking multiple people to rate the validity of a test using a Likert scale. Like external validity, construct validity is related to generalizing. 3) factorial validity. It can be specified that internal validity refers to how the research findings match reality, while external validity refers to the extend to which the research findings can be replicated to other environments (Pelissier, 2008, p.12). They can be difficult to measure accurately because they often involve assessing traits or behaviors that might lead to different interpretations depending on who is observing them.

Additionally, the validity of a particular scale can be measured in terms of its face value, scope of measurement, predictive power, and ability to measure the thing that it is intended to measure. - Average scores, indicates valid protocol If L Scale T Score is < 50: - Willing to admit to minor faults and shortcomings - Some cases may be exaggerating negative characteristics or being very self-critical (especially if F high & K also low) - True response bias (TRIN high in true direction) Because inferences drawn using flawed or compromised scales are meaningless, scale validation and measurement remains one of the most important and involved phases of empirical research. The relevant evidence includes the measure's reliability, whether it covers the construct of interest, and whether the scores it produces are correlated with other variables they are expected to be correlated with and not correlated with variables that are conceptually distinct. In our previous example of firm performance, since the recent financial crisis impacted the performance of financial firms disproportionately more than any other type of firms such as manufacturing or service firms, if our sample consisted only of financial firms, we may expect a systematic reduction in performance of all firms in our sample due to the financial crisis.

Finally, predictive validity was measured by determining if baseline PSS-PW and PSS-NW scores differentially predict the development of aMCI. If this correlation matrix shows high correlations within items of the organisational knowledge and organisational performance constructs, but low correlations between items of these constructs, then we have simultaneously demonstrated convergent and discriminant validity (see Table 7.1). Validity questions are used to try to detect people 'faking' the test but these questions are fairly easy to spot.
