All participants experienced a motor vehicle accident (MVA) and reported pain due to accident-related injuries (n=183). Structural equation modeling was used to develop two models hypothesizing a relationship between PTSD symptomatology, pain severity, and perceived life control. Separate models were constructed for psychosocial and physical functioning, based on the hypothesis that pain and PTSD would be differentially related to disability in these two domains. Results suggested that more severe PTSD symptoms and greater pain complaints were related to psychosocial impairment, however, only pain was significantly related to impairment in physical functioning. Perceptions of life control were shown to further explain these interrelationships....
