قرار گرفتن در معرض تروما، اختلالات روانی در حادثه و انتقال اختلالات در یک نمونه نمایندگی طولی جمعیت

Heterotypic continuity, whereby individuals transition from one disorder to another, is common; however, longitudinal studies examining transdiagnostic predictors of heterotypic continuity are lacking. The current study examined whether trauma exposure during childhood (maltreatment) and adulthood (interpersonal and non-interpersonal trauma) is associated with heterotypic continuity in a national sample. Men and women (N = 34,653) who participated in Waves 1 (2001–2002) and 2 (2004–2005) of the National Survey of Alcohol and Related Conditions (NESARC) completed face-to-face interviews about trauma exposure and psychopathology. Risk ratios and population attributable risk proportions (PARPs) quantified the effects of childhood maltreatment and interpersonal and non-interpersonal trauma exposure between Waves 1 and 2 on risk for incident disorders and transitions between specific types of disorders. Twenty percent of respondents reported a Wave 2 incident disorder. Those with any Wave 1 disorder were at increased risk of incident mood (RR range = 1.2–2.1) and anxiety (RR = 1.5–2.7) disorders at Wave 2. Child maltreatment and interpersonal trauma exposure since Wave 1 were associated with roughly 50% of the risk for disorder transitions (RR range = 1.2–2.7); non-interpersonal trauma was associated with 30% of the risk for disorder transitions (RR range = 1.0–1.7). Findings suggest that new onset disorders were common in U.S. adults and trauma exposure explained a large proportion of disorder incidence as well as progression from one disorder to another. Universal prevention efforts that begin early in life, rather than those targeted at specific disorders, would be fruitful for reducing the burden of population mental health and preventing a cascade of mental disorders over the life course.
