Lifetime comorbidity with additional psychiatric disorders and suicide attempts among individuals with PTSD-AD was remarkably high. To the extent that comorbidity may be the result of a latent variable underlying multiple diagnoses (Blanco et al., 2013; Krueger et al., 1998), higher rates of additional psychopathology may be another index of the severity of the disorder (Bolton et al., 2010; Bolton and Robinson, 2010; Nepon et al., 2010). Moreover, the existence of additional comorbidities may also contribute to a greater psychological impairment, which is linked to poorer coping mechanisms and may lead to higher risk for suicidal attempts (Nepon et al., 2010). Despite the high severity and high rate of suicide attempts among individuals with PTSD-AD, they were neither more likely to seek treatment for PTSD than those with PTSD only nor more likely to seek treatment for AD than those with AD only. Lower socioeconomic status among individuals with PTSD-AD may limit their access to mental health services. Alternatively, the use of alcohol to relieve their symptoms may lead to decreased motivation to seeking professional help. Conducting screening and promoting
