When studies on a given topic lead to similar conclusions, the measurements show

Correct option is A

Convergent validity refers to the degree to which two measures of constructs that theoretically should be related, are in fact related. When different studies on a given topic yield similar results or conclusions, it suggests that the measures used are indeed assessing the same underlying construct, thus demonstrating convergent validity.

·         Criterion validity assesses how well one measure predicts an outcome based on another measure, often a "gold standard" or external criterion. It is not directly related to the consistency of results across different studies.
·         Divergent validity, also known as discriminant validity, involves measures of constructs that should not be related to each other. This is the opposite of convergent validity and does not concern the similarity of results across studies.
·         Construct validity is the overall assessment of how well a test measures the concept or construct it's intended to measure. While it encompasses both convergent and divergent validity, it's not specifically about the similarity of conclusions across multiple studies.
