Using explanatory models to understand chronic symptoms of Cambodian refugees.

BACKGROUND

Case reports indicate that understanding patients' "explanatory models" can improve diagnosis, patient compliance, and satisfaction. However, few studies have examined explanatory models within specific cultural groups to understand their symptoms.

METHODS

Seventy-six older Cambodian refugees were interviewed using measures of symptom frequency, explanatory models, help-seeking patterns, and use of traditional Cambodian remedies. Psychiatric patients were compared with non-patients.

RESULTS

Headache was the most common symptom, reported by 58% of those interviewed, and also the most frequent chief complaint (41%). Headache was reported in both groups but was reported by significantly more psychiatric patients. Headache was positively associated with the diagnosis of depression. More than half explained their headaches as a result of sadness, grief, and anxiety. Explanatory models did not differ significantly between groups. All participants maintained Cambodian medical beliefs, and 83% used traditional Cambodian remedies.

CONCLUSIONS

Results suggest a high prevalence of headache among older Cambodian refugees, for whom it may be a manifestation of depression. Emphasis on this somatic complaint does not preclude patients' recognition of psychological factors. Addressing explanatory models can help clinicians determine underlying etiology and understand challenging patients.
