Patterns of Posttraumatic Stress Disorder and Posttraumatic Growth Among Adolescents After the Wenchuan Earthquake in China: A Latent Profile Analysis.

Posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) often coexist in the survivors of traumatic events. The current study examined the coexisting patterns of PTSD and PTG using latent profile analysis in a sample of 591 adolescent survivors of the May 12, 2008 Wenchuan earthquake in China. Logistic regression analysis was used to examine the effects of traumatic exposure on specific coexisting patterns. A three-class solution characterized by a growth group (39.6%), a low symptoms group (10.3%), and a coexistence group (50.1%) fitted the data best. Members of the low symptoms group were more likely to be male, odds ratio (OR) = 2.67, 95% CI [1.48, 4.81]; and adolescents in the coexistence group were more likely to be older, OR = 1.22, 95%CI [1.09, 1.37], and to have had experienced serious indirect exposure, OR = 1.07, 95% CI [1.02, 1.12], and posttraumatic fear, OR = 1.20, 95% CI [1.11, 1.31].
