Multivariate analysis of variance testing effect of posttraumatic stress disorder on self-reported health and physical performance.

Variable	Estimate	Standard Error	p-Value
Self-Reported Health Status (SF-36)
Physical Component Summary Score	−0.95	1.45	0.51
Physical Function	−8.96	3.30	0.01
Role-Physical	−22.28	5.62	<0.01
Bodily Pain	−4.74	3.78	0.21
General Health	−9.01	2.89	<0.01
Physical Performance
SPPB (0–12)	−0.68	0.26	0.01
Six-Minute Walk Test (m)	3.83	16.72	0.82
Usual Gait Speed (m/s)	−0.06	0.04	0.11
Rapid Gait Speed (m/s)	−0.05	0.06	0.37
Grip Strength (kg)	0.63	1.23	0.61

Note: All models controlling for age, race, education, number of comorbidities, body mass index, and depression.

SF-36 = 36-item Short Form Health Survey, SPPB = Short Physical Performance Battery.
