Correlations with the AMAT-9

	Spearman rank correlation coefficient (r)	p-value
Hypothesis #1
ARAT	0.79	0.001
FMA – total	0.79	0.001
FMA – W/H	0.74	0.001
FMA – S/E	0.66	0.001
WMFT	0.78	0.001
Hypothesis #2
SIS – Hand	0.40	0.025
SIS – Comm*	−0.16	0.39

Spearman rank order correlation coefficient (r) between the AMAT-9 and various upper extremity assessments for the 32 baseline assessments. Hypothesis #1 (see text) is partially supported in that there are strong correlations between the AMAT-9 and the other measures, but the WMFT was not the strongest, as hypothesized. The data fully supports hypothesis #2 (see text) regarding the divergent construct validity of the AMAT-9. AMAT-9: Arm Motor Ability Test (9 item version); ARAT: Arm Research Action Test; FMA: Fugl Meyer Assessment; W/H: wrist/hand subscore; S/E: shoulder/elbow subscore; SIS: Stroke Impact Scale; Hand: Hand Function subscore; Comm: Communication subscore.
