In the context of validity, which of the following types is concerned with how well a test predicts future performance?

Criterion-related validity is specifically focused on the effectiveness of a test in predicting outcomes or performance in a specific criterion or future situation. This type of validity is important when evaluating tests that aim to forecast an individual's behavior or performance in real-world tasks based on their scores. There are two main aspects of criterion-related validity: concurrent validity, which assesses the correlation between the test and a criterion assessed at the same time, and predictive validity, which evaluates how well the test forecasts future performance.

In the context of psychological testing, understanding criterion-related validity helps ensure that the instruments used are actually indicative of how individuals will perform in related future scenarios, thus making it a crucial component of test development and evaluation. The other types of validity, such as content validity, construct validity, and face validity, do not primarily focus on this predictive aspect.

Content validity looks at whether a test adequately samples the content it is intended to measure, while construct validity refers to how well a test measures the theoretical construct it claims to measure. Face validity, on the other hand, simply assesses whether the test appears to measure what it is supposed to measure based on subjective judgment. None of these types specifically address the predictive capabilities that criterion-related validity does.
