Note: We report differences between chronological and developmental ages for the McCarthy Draw-a-Child, Words and Sentences, and Digit Span Forward and Backward subtests (in months). Raw scores are reported for the gross motor tasks of the McCarthy scales (no developmental ages are available for these subtests) and for the CBCL as recommended by the test manual [42]. Standardized scores are used for other tests.
