Multiple logistic regression model for association factors of current PTSD^a

Variable	Univariate OR (95% CI)	P value	Multiple logistic regression, adjusted OR (95% CI)	P value
Functional impairment checklist–disability score	2.44 (1.66–3.56)	<.001	3.82 (1.71–8.51)	<.001
Chance locus of control	1.22 (1.09–1.37)	<.001	1.52 (1.16–1.97)	<.001
Average pain	1.69 (1.31–2.19)	<.001	1.66 (1.01–2.71)	.019

^aFactors to enter to stepwise forward multiple logistic regression include average pain scale in the past months, functional impairment checklist, perceived inadequacy of social support, involvement in litigation and compensation, subjective perception of dangerousness during the SARS outbreak, subjective perception of being stigmatized during the SARS outbreak, CWCQ scales and MHLC scales.
