Starting with definition, one of the main stumbling blocks concerns ambiguity in the criterion for delayed onset in DSM. In this context, Sparr and Pankratz (5) reported five cases of factitious PTSD among men presenting at a VA medical center claiming to be Vietnam veterans.īefore summarizing the literature, we discuss sources of variation in definition, design, and assessment that have a bearing on inclusion criteria for studies in our review and evaluation of the evidence. (4) cautioned against accepting all claims of delayed onset as genuine because of the secondary gains involved. Within 2 years of the publication of DSM-III, Atkinson et al. Veterans Administration (VA), which in turn led to a rise in benefit claims for the disorder, presumably by veterans previously denied the opportunity (4). The inclusion of delayed-onset PTSD in DSM-III led to its acceptance as a potentially compensable disorder by the U.S. It is also specifically noted that PTSD symptom onset usually occurs within 3 months after the trauma, indicating that delayed onset is the exception to the rule. This criterion has remained consistent in all editions since its introduction in DSM-III. The wide variety of research designs and definitions of delayed onset in the literature precludes the use of formal meta-analytic techniques.ĭSM-IV-TR describes delayed onset as a specifier for PTSD indicating “that at least 6 months have passed between the traumatic event and the onset of the symptoms” (p. We also examine evidence for triggers to onset from the case reports and review the evidence for initial differences between individuals with delayed-onset, acute-onset, and no PTSD from the group studies. In this article, anticipating the possible revision of the PTSD entry in DSM-V, we attempt to resolve these conflicting findings through a systematic review of the evidence from both case and group studies. Reported rates have varied between 0% and 68% of PTSD cases, and some authors have even expressed skepticism about whether the condition exists at all (2, 3). ![]() Since then, numerous studies have investigated the condition in samples of combat veterans and civilians, with no consensus emerging as to its prevalence. Its inclusion in DSM was based on existing literature indicating that many soldiers do not develop symptoms until they return home, as stress reactions are not adaptive in combat (1). The delayed-onset subtype of posttraumatic stress disorder (PTSD) was formally described in 1980 when PTSD was first recognized as a diagnostic entity in DSM-III. Continuing scientific study of delayed-onset PTSD would benefit if future editions of DSM were to adopt a definition that explicitly accepts the likelihood of at least some prior symptoms. Little is known about what distinguishes the delayed-onset and immediate-onset forms of the disorder. ![]() Conclusions: The discrepant findings in the literature concerning prevalence can be largely, but not completely, explained as being due to definitional issues. Studies consistently showed that delayed-onset PTSD in the absence of any prior symptoms was rare, whereas delayed onsets that represented exacerbations or reactivations of prior symptoms accounted on average for 38.2% and 15.3%, respectively, of military and civilian cases of PTSD. ![]() Results: Ten case studies and 19 group studies met criteria for inclusion in the review. Studies were also examined for differences between immediate-onset PTSD, delayed-onset PTSD, and no-PTSD cases. Studies that met inclusion criteria were examined for the defined length of delay for delayed-onset PTSD, presence of symptoms before full diagnostic criteria were met, length of follow-up, prevalence estimates, and other variables. Method: A literature search was conducted for case reports and group studies with adequate measurement of delayed-onset PTSD according to DSM criteria. The authors sought to resolve discrepant findings concerning the prevalence of delayed-onset PTSD by conducting a systematic review of the evidence. Objective: Since the diagnosis of delayed-onset posttraumatic stress disorder (PTSD) was introduced in DSM-III, there has been controversy over its prevalence and even its existence. ![]()
