Responses to a mail survey were used to investigate the contribution of PTSD symptom severity to work functioning in 69 previously employed adult survivors of accidental injury approximately 8 months post‐hospitalization. Associations of PTSD symptom severity with other established risk factors for poor work functioning were also examined. Participants were initially divided into three groups based on PTSD symptom severity and analysis of variance undertaken to determine the differences in work functioning between survivors with PTSD, subclinical PTSD, and no PTSD. As anticipated, survivors with PTSD reported significantly poorer work functioning than those with subclinical PTSD and no PTSD. Those with subclinical PTSD, however, reported significantly lower levels of work functioning than survivors with no PTSD, suggesting that this population may also be at risk of poor outcomes and in need of vocational interventions post‐accident. To determine the influence of PTSD symptom severity on work functioning over and above other established risk factors, a two‐model hierarchical regression that included the established risk factors in the first model and PTSD in the final model was undertaken. Results revealed that PTSD symptom severity uniquely predicted work functioning after controlling for the influence of other contributing risk factors. A composite of seven risk factors, including PTSD symptom severity, was shown to predict 62% (57% adjusted) of the variance in work functioning but only pre‐accident occupation, physical functioning, and PTSD severity significantly contributed to the prediction. Findings suggest that the rehabilitation management of people with PTSD or subclinical PTSD following accidental injury would benefit from early identification by the established predictors together with an integrated approach to physical, psychological, and vocational interventions.
