Generalized pain is associated with more negative consequences than local or regional pain: a study of chronic whiplash-associated disorders.

OBJECTIVE

The main aims of this study were: (i) to determine, for chronic whiplash-associated disorders, whether widespread pain has more severe consequences for other symptoms and different aspects of perceived health than does local/regional pain; (ii) to investigate whether pain, depression, and symptoms not directly related to pain are intercorrelated and to what extent these symptoms correlate with catastrophizing according to the Coping Strategy Questionnaire.

DESIGN

Descriptive cross-sectional study.

PATIENTS

A total of 275 consecutive chronic pain patients with whiplash-associated disorders who were referred to a university hospital.

METHODS

Background history, Beck Depression Inventory, Coping Strategy Questionnaire, Life Satisfaction Checklist, the SF-36 Health Survey and EuroQol were used to collect data.

RESULTS

Spreading of pain was associated with negative consequences with respect to pain intensity and prevalence of other symptoms, life satisfaction/quality and general health. The subjects differ with respect to the presence of symptoms not directly related to pain. A minor part of the variation in Back Depression Inventory was explained by direct aspects of pain, indicating that, to some extent, generalization of pain is related to catastrophizing thoughts.

CONCLUSION

Widespread pain was associated with negative consequences with respect to pain intensity, prevalence of other symptoms including depressive symptoms, some aspects of coping, life satisfaction and general health.
