A clinical psychologist develops a new 10-item questionnaire designed to screen for generalized anxiety disorder. To assess its validity, they administer both this new questionnaire and an established, widely accepted diagnostic interview to a sample of 80 patients during the same clinical session. A strong positive correlation (r=0.84r = 0.84r=0.84) is found between the scores of the two assessments.
Which type of validity is directly established by this high correlation?
Face validity
Concurrent validity
Predictive validity
Ecological validity
