There Has Been a Recent Increase in Attention to and Research

There has been a recent increase in attention to and research in assessment. That said, use of effective assessment tools may be decreasing because:

A) today's clinicians simply aren't trained well enough in their uses.
B) most assessment tools are too simplistic, and patients can figure out the "right" answers.
C) there are too many from which to choose.
D) they are expensive to administer and evaluate.
