A clinical psychologist develops a new self-report questionnaire, the Anxiety Symptom Scale (ASS-10), to measure generalized anxiety. To assess its validity, she administers the ASS-10 to a sample of 150 patients. At the same time, she administers the widely recognized and clinically validated Beck Anxiety Inventory (BAI) to the same patients, and finds a strong positive correlation (r=+0.82r = +0.82r=+0.82) between the two sets of scores.
