Professor Cantu develops a new measure of depression. He finds that scores on his new measure correlate well with scores on existing well-validated measures of depression, but that scores on his new measure also correlate well with scores on well-validated measures of anxiety. The results of Professor Cantu's research suggest that there is a problem with the ________ of his new measure.

You are developing a new self-report measure of depression. You find that it has an internal consistency coefficient of .90 and a one month test-retest correlation of .80. It also has a correlation of r = -.10 with clinicians' ratings of the respondents' degree of depression. On the basis of this evidence, you would be justified in concluding that the measure has
