Using a Biopsychosocial Model to Understand Long-Term Outcomes in Persons With Burn Injuries.

OBJECTIVE

To determine the importance of preburn adjustment, injury-related variables, and selection of coping style in various outcome measures using a biopsychosocial model.

DESIGN

Longitudinal study.

SETTING

Outpatient burn clinics.

PARTICIPANTS

Burn survivors (N=231) who participated in this study as part of a larger burn model system study of 645 patients with major burn injuries.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The 36-Item Short-Form Health Survey was used to assess preburn adjustment. Other outcome measures entered into the model included the Ways of Coping Checklist Revised, the Brief Symptom Inventory, the Beck Depression Inventory-II, and the Davidson Trauma Scale.

RESULTS

Correlational and mediational analyses revealed that preburn emotional health predicted better adjustment at year 1 and more posttraumatic stress disorder symptoms at year 2. Better preburn emotional health was also related to less use of avoidance coping strategies, which was found to be a mediator of the effect of preburn emotional health and posttraumatic stress disorder symptoms. Burn injury characteristics were not significantly associated with psychological adjustment at either year 1 or year 2.

CONCLUSIONS

The results indicate that there is a complex relation between premorbid mental health and the selection of coping strategies that affect long-term adjustment in persons recovering from a burn injury. This relation seems to have greater effect on long-term outcomes than does preburn emotional or physical health alone or the severity of the burn.
