† Child Development Review-Parent Questionnaire is also available; 32 questions require 10-20 minutes to complete. Sensitivity is low (68%) and specificity is adequate (88%).
‡ There is no single scoring method yielding adequate sensitivity and specificity. If "no opportunity" is scored as a fail, most affected children will be referred but with substantial over-referrals. If "no opportunity" is scored as a pass, then over-referrals are minimized but many children with needs will be missed.
