A clinician is treating an adolescent with conduct disorder. The adolescent has been in foster care since his parents died many years ago, so there is limited information about his early behavior. The clinician has learned that recent research suggests there may be neuropsychological involvement when the onset of conduct disorder occurs at a young age, but not at an older age. The neurological tests required would be very expensive to conduct, so the researcher is unsure whether they should be added to the tests she is already using. In this case, the researcher is probably concerned with ______.
A) the construct validity of the neurological test
B) the face validity of the neurological test
C) the concurrent evidence of validity for the neurological test
D) the incremental validity of the neurological test

Question

Quizplus · Accepted Answer

The researcher's concern about whether the neurological tests should be added to the tests already being used indicates a consideration of the incremental validity of the neurological test. The researcher is weighing whether the additional information gained from the expensive neurological tests is worth the cost and effort, and whether it would add meaningfully to the information already being gathered through other tests. The other options do not directly apply to the researcher's concerns in this scenario.
