Abstract Previous research established that 78\% of a sample of motor vehicle accident survivors initially diagnosed with acute stress disorder (ASD) were subsequently diagnosed with posttraumatic stress disorder (PTSD) at 6 months posttrauma. Although the previous study provided initial evidence for the utility of the ASD diagnosis, the relationship between ASD and PTSD was assessed over a relatively short period. The present study reassessed that original sample 2 years following the trauma to establish the longer term relationship between ASD and PTSD. ASD was diagnosed in 13\% of participants, and 21\% were diagnosed with subsyndromal ASD. In terms of participants who participated in all 3 assessments, 63\% who met the criteria for ASD, 70\% who met the criteria for subsyndromal ASD, and 13\% who did not meet the criteria for ASD were diagnosed with PTSD at 2 years posttrauma. These findings indicate the importance of considering multiple pathways to the development of PTSD.
