What type of validity is indicated when results from a second survey reinforce the findings of the first survey?

The scenario described pertains to construct validity. Construct validity refers to the degree to which a survey or assessment accurately measures the theoretical concept or construct it is intended to measure. When results from a second survey reinforce the findings of the first survey, it provides evidence that the construct being measured is consistently reflected across different instances of measurement. This consistency supports the conclusion that the measurements are indeed capturing the intended theoretical constructs effectively.

In contrast, criterion validity pertains to how well one measure predicts an outcome based on another measure. Content validity concerns whether the survey items comprehensively cover the construct being measured. Internal validity involves the extent to which a study accurately establishes cause-and-effect relationships within its own context, rather than indicating consistency in measuring a theoretical construct across different surveys. Thus, the reinforcing results from a second survey demonstrate support for the construct's validity by showing that the same underlying concept is being consistently measured.
