Quizplus · Accepted Answer

A positive correlation with an existing measure of ADHD would help support Martin's case, as problems with attention are often associated with ADHD. A negative correlation with an existing measure of ADHD would actually weaken Martin's case, as it would suggest that his scale is measuring something different from ADHD. A positive correlation with an existing measure of mood problems may suggest that Martin's scale is measuring something related to mood, rather than attention problems. Therefore, only choice A would establish the construct validity of Martin's new scale.
