Clinician-rated vs Self-Report Descriptive Statistics and Internal Consistencies for the Total Functional Capacity, Functional Assessment, and Independence Scale

		Clinician Ratings		Self-Report Ratings		Clinician vs. Self-Report ratings
Variable	N	Mean (SD)	Internal Consistency (Cronbach’s Alpha)	Mean (SD)	Internal Consistency (Cronbach’s Alpha)	Mean Scores T (df)	Internal Consistency T (df)
Total Functional Capacity	470	9.54 (3.68)	0.89	9.22 (3.97)	0.86	6.10 (469)**	4.75 (468)**
Functional Assessment	303	19.02 (6.30)	0.948	20.90 (5.57)	0.942	1.01 (302)	2.16 (301)*
Independence Scale	482	8.55 (1.61)	-	8.84 (1.58)	-	6.24 (481)**	-

Note: T(df) denotes the t-value (degrees of freedom) from the paired t-tests comparing the clinician and self-report measures; Independence Scale has no Cronbach’s Alpha as it is a single-item measure.
