Pearson's correlation coefficients between scores on the 3 sections of the index test and the total scores on the WAB AQ, AMSD, and WAB NLS

STAD	WAB AQ (n = 57)	AMSD (n = 84)	WAB NLS (n = 71)
Verbal section	0.891	0.669	0.668
Articulation section	0.456	0.702	0.563
Nonverbal section	0.423	0.658	0.793

Pearson's correlation coefficient values of 0.30, 0.50, and 0.70 correspond to linear, moderate, and strong linear relationships, respectively. AMSD, Assessment of Motor Speech for Dysarthria; STAD, Screening Test for Aphasia and Dysarthria; WAB AQ, Western Aphasia Battery aphasia quotient; WAB NLS, Western Aphasia Battery nonlinguistic skills.
