Table 2.

Speech sound measures for the TD, SSD-only, and SSD+LI groups.

	TD		SSD-only		SSD+LI		F	p	η²
	M	SD	M	SD	M	SD	F	p	η²
GFTA percentile rank^a,^b	62.95	25.11	35.70	26.74	22.40	26.09	12.65	<.0001	0.31
PCC^a	92.23	3.88	86.09	6.56	89.51	7.64	4.42	.0172	0.15
KLPA percentile^a,^b	63.15	23.67	30.90	29.59	19.10	23.65	15.64	<.0001	0.35

Note. GFTA = Goldman-Fristoe Test of Articulation (Goldman & Fristoe, 1986), PCC = percentage of consonants correct, and KLPA = Khan-Lewis Phonological Analysis (Khan & Lewis, 1986).

SSD-only group differs from the TD group.

SSD+LI group differs from the TD group.
