Which form of validity is concerned with the correlation between the results of an assessment and results from other measures of similar constructs?

The focus of the question is on the correlation between the results of an assessment and other measures of similar constructs. The most appropriate form of validity that addresses this relationship is convergent validity.

Convergent validity refers to the degree to which two measures of constructs that are theoretically related are, in fact, correlated. This form of validity supports the validity of a measure by demonstrating that it correlates well with other measures that it should theoretically relate to, based on established theories or constructs.

Criterion validity, on the other hand, is concerned with how well one measure predicts an outcome based on another, often used in assessing how effective a test is in predicting a person's performance based on a different, validated measure. While it is also a form of validity, it does not specifically address the correlation between results of assessments of similar constructs.

Construct validity encompasses both convergent and discriminant validity and assesses whether a test truly measures the theoretical construct it intends to measure. Discriminant validity, in contrast, focuses on the absence of a relationship between measures that are not supposed to be related.

In summary, convergent validity is the correct answer as it directly involves assessing the correlations between similar constructs which supports the credibility of the assessment in question.
