Examining the Latent Structure of Acute Stress Disorder Symptoms in Filipino-Victims of a Flashflood Disaster.

Although Acute Stress Disorder (ASD) was introduced in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition for a number of years already, only few studies have examined ASD in its latent level. Utilizing 998 respondents who experienced a deadly flashflood, the results revealed that of the 7 models, Dysphoric arousal model fitted best whereas the new DSM-5 single factor model received the lowest fit. The findings of the study are pertinent in the current changes of ASD in DSM-5 and would elucidate further ASD's latent structure that best represent Asian sample, particularly Filipinos.
