Posttraumatic Stress Disorder and Psychiatric Comorbidity Among Detained Youths

Abstract

Most youth in detention have 1 or more psychiatric disorders (1). Posttraumatic stress disorder (PTSD) is one of the more prevalent disorders in detention, affecting at least 1 in 10 youth (2–4). One of the more debilitating aspects of PTSD is its tendency to co-occur with other psychiatric disorders (5–7). In a community sample, Giaconia and colleagues (8) found that nearly four-fifths of those with lifetime PTSD also had one or more additional disorders. Studies of detained adolescent males in Russia (9) and detained adolescent females in Australia (10) found that all of the detainees with PTSD had at least 1 comorbid disorder. It is unclear if PTSD increases the vulnerability to other disorders or if there are common genetic or environmental factors underlying the disorders (5,11). Researchers agree, however, that comorbid disorders have an adverse impact on the prognosis and treatment of individuals with PTSD. Youth with PTSD and comorbid disorders have significantly more behavioral and health problems and more impaired interpersonal relationships than those without comorbid disorders (5). Effective treatment planning for detained youth with PTSD requires epidemiologic data on patterns of prevalence and comorbidity. Yet, to our knowledge, no epidemiologic study of detainees in the US has examined PTSD and comorbid psychiatric disorders. In this paper, we administered standardized diagnostic measures to a large, stratified random sample of detained youth to: (a) compare the prevalence of psychiatric disorders among juvenile detainees with and without PTSD and (b) examine the prevalence of PTSD among youth with and without other psychiatric disorders.
