title: Posttraumatic stress disorder and its comorbidities among American Indian veterans.
abstract: Goal consists of describing the demographic and comorbid characteristics associated with Posttraumatic Stress Disorder (PTSD) among American Indian veterans with any lifetime Axis 1 disorder. Sample included 252 American Indian veterans, obtained from a community sample of 557, using targeted sampling designed to provide a representative sample, structured to include equal numbers of rural and urban veterans and a twofold over sample of women. Data collection involved lifetime diagnoses based on the Diagnostic Interview Schedule/Quick Version/DSM-III-R, demographic characteristics, and combat exposure. Findings Bivariate comparisons showed positive relationships of PTSD with combat exposure, mood disorder and anxiety disorders (excluding PTSD), but a negative relationship with substance use disorder. Binary logistic regression analyses showed an independent association of PTSD with mood and anxiety disorders as well as combat exposure.
