Child and Family Factors	NTU (R² = .18, p = 0.02)		NDW (R² = .21, p = 0.01)		MLUm (R² = .52, p < 0.001)		High-Level (R² = .43, p = < 0.001)		Directing (R² = .27, p < 0.001)
Child and Family Factors	β	p	β	p	β	p	β	p	β	p

Note. NTU = number of total utterances; NDW = number of different words; MLUm = mean length of utterance in morphemes; BEPTA = better-ear pure tone average; HA = hearing aid.
