A clinical psychologist designs a new self-report questionnaire to measure generalized anxiety levels in adolescents. To assess its validity, they administer both the new questionnaire and a well-established, highly respected diagnostic scale (the GAD-7) to a cohort of 100 participants during the same session. They calculate a correlation coefficient of r=+0.87r = +0.87r=+0.87 between the two sets of scores.
Which type of validity is established by this strong positive correlation?
Construct validity
Concurrent validity
Predictive validity
Ecological validity
