Background The current study investigated the underlying dimensionality of DSM ‐5 posttraumatic stress disorder ( PTSD ) symptoms in a trauma‐exposed Chinese adolescent sample using a confirmatory factor analytic ( CFA ) alternative model approach. Methods The sample consisted of 559 students (242 females and 314 males) ranging in age from 12 to 18 years ( M = 15.8, SD = 1.3). Participants completed the PTSD Checklist for DSM ‐5 , the Major Depression Disorder and Panic Disorder subscales of the Revised Children's Anxiety and Depression Scale, and the Aggressive Behavior subscale of the Youth Self‐Report. Results Confirmatory factor analytic results indicated that a seven‐factor model comprised of intrusion, avoidance, negative affect, anhedonia, externalizing behavior, anxious arousal, and dysphoric arousal factors emerged as the best‐fitting model. Further analyses showed that the external measures of psychopathological variables including major depressive disorder, panic disorder, and aggressive behavior were differentially associated with the resultant factors. Conclusions These findings support and extend previous findings for the newly refined seven‐factor hybrid model, and carry clinical and research implications for trauma‐related psychopathology.
