Why don’t the MMO/18-59 and MFAM display cross-informant comparisons of adaptive functioning scores?

Answer: The ABCL yields scores for only two adaptive functioning scales, whereas the ASR yields scores for five scales, plus an overall mean adaptive functioning score. Because users can easily compare ASR and ABCL scores on the two adaptive functioning scales they have in common, bar graph displays are unnecessary.
