Prospective examination of daily life traumatic stress symptom expression following motor vehicle collisions.

Objective: Motor vehicle collisions (MVCs) are a common source of traumatic stress, which could lead to the development of posttraumatic stress disorder. However, the natural course of symptom development is still poorly understood. The current study aimed to prospectively examine the expression of traumatic stress symptoms in mild-moderate injured MVC survivors, using a novel daily life repeated measurement approach.
