The 1-factor model offered the most compelling balance of sensitivity and specificity, with the 2-factor model and the Dysphoria model following closely behind. ![]() These two models also only showed small levels of convergence with CBCL dimensions. The Dysphoria and PTSD-6Y models offered the better accounts of symptom structure, although neither satisfied minimum requirements for a good fitting model. Criterion related validity was established by comparing each model to a categorical rating of impairment. Convergent validity was established against the Child Behavior Checklist (CBCL). The model was compared to DSM-IV, a 4-factor ‘dysphoria’ model that groups symptoms also associated with anxiety and depression, and alternate 1- and 2- factor models. Data for N = 284 (3–6 years) trauma-exposed young children living in New Orleans were recruited following a range of traumas, including medical emergencies, exposure to Hurricane Katrina and repeated exposure to domestic violence. This study utilized confirmatory factor analytic techniques to evaluate the proposed DSM-5 PTSD-6Y factor structure and criterion and convergent validity against competing models. A subtype of the posttraumatic stress disorder diagnosis for children 6 years and younger (PTSD-6Y) was introduced in the Diagnostic and Statistical Manual, Fifth Edition (DSM-5). ![]()
