The authors investigated whether expressive and receptive language, phonological, articulatory, and/or verbal working memory proficiencies aid in predicting eventual recovery or persistence of stuttering in preschool children. Receptive language, expressive language, and verbal working memory abilities did not distinguish children who stuttered but recovered from children who stuttered who stuttered and persisted. Preschool Bankson-Bernthal Test of Phonology-Consonant Inventory subtest (BBTOP, Bankson & Bernthal, 1990 ) scores and overall Nonword Repetition Test (NRT, Dollaghan & Campbell, 1998) proficiency significantly predicted future recovery status.
