Convergent and discriminant validity are often evaluated together because they both involve assessing the degree to which a psychological measure relates to other measures. Convergent validity focuses on the extent to which a measure correlates with other measures of the same construct, indicating that they are measuring the same concept. Discriminant validity assesses the degree to which a measure does not correlate with measures of different constructs, ensuring that the measure is distinct from other constructs. Both types of validity involve comparing the measure in question with a range of other psychological measures to establish these relationships, hence the need for collecting information from various measures of theoretical interest.
