Linear regression models comparing Mississippi PTSD scores in AI Vietnam veterans with and without conduct disorder

Model #	Adjustment variables	Conduct Disorder M (SD)^b	No Conduct Disorder M (SD)^c	95% CI^a for difference
1	(none)	99.4 (21.0)	90.6 (22.5)	(4.9 – 12.7)^*
2	High war zone stress	99.5 (19.7)	90.6 (20.5)	(4.6 – 11.7)^*
3	High war zone stress + all covariates^d	99.5 (18.4)	90.8 (20.5)	(3.9 – 10.9)^*

CI = confidence interval.

Mean Mississippi PTSD score for veterans with conduct disorder.

Mean Mississippi PTSD score for veterans without conduct disorder.

Includes psychosocial variables before military service (trauma, PTSD, mental illness, alcohol and/or drug abuse, and alcohol and/or drug dependence), sociodemographic variables at entry to military (age, education, employment status), and military service factors (military status, officer rank).
