Note. SSD = speech sound disorders; LI = language impairment; MSW = Multisyllabic Word Repetition task; NSW = Nonsense Word Repetition task; EOWPVT-2 = Expressive One Word Picture Vocabulary Test–Second Edition; PPVT-4 = Peabody Picture Vocabulary Test–Fourth Edition; WA = Word Attack subtest of the Woodcock Reading Mastery Tests–Revised (WRMT-R); WI = Word Identification subtest of the WRMT-R; TWS-3 = Test of Written Spelling–Third Edition; RC = Reading Comprehension subtest of the Wechsler Individual Achievement Test (WIAT); CELF-3 = Clinical Evaluation of Language Fundamentals–Third Edition.

^aNo SSD-EC differs from SSD only.

^bNo SSD-EC differs from SSD + LI.
