Construct validity explores how well the measure aligns with the theory behind the measure. For example, if theory suggests a concept is multidimensional (e.g., personality), then the measure should reflect this with for example, subscales measuring each of the dimensions of personality indicated by a particular theory (structural validity). Construct validity can also be explored by using measures of similar (convergent validity) and dissimilar constructs (divergent validity). For example, two measures of anxiety would be expected to be highly positively corelated, but a measure of anxiety would not be expected to be highly positively correlated with a dissimilar construct such as ADHD.
