Table 2.

Relative risk of past year PTSD at Wave II among those reporting exposure to new assault or witnessed violence since Wave I (n=733).

	Bivariate Associations OR (95% CI)	Multivariate Model Adjusted OR (95% CI)
Prior assault or witnessed violence/PTSD vs no prior Exposure	2.69 (1.33 – 5.44)^**	1.89 (0.68 – 5.26)
Prior assault or witnessed violence/no PTSD vs no prior Exposure	1.64 (0.99 – 2.73)	1.71 (0.99 – 2.95)
Prior assault/no PTSD vs no prior assault/no PTSD	2.11 (1.25 – 3.56)^**	2.03 (1.10 – 3.76)^*^a
Prior witnessed violence/no PTSD vs no prior witnessed violence/no PTSD	1.11 (0.67 – 1.85)	0.98 (0.54 – 1.79)^a

OR=Odds Ratio; CI=Confidence Interval. Multivariate models were adjusted for gender, ethnicity, Wave I alcohol/drug abuse or dependence, Wave I lifetime depression, and Wave II age and education.

Variables for both Wave I assault and witnessed serious violence were included as predictors in these regression models.
