Abstract

THEORY/OBJECTIVE: Somatoform disorder (SFD) is associated with considerable psychosocial impairment. However, only a few studies have dealt with the course of this clinical subgroup. Therefore, the objective was to identify predictors for the various courses of SFD and medically unexplained symptoms (MUS).

METHOD:

We screened 620 consecutive patients in primary care using the Patient Health Questionnaire (PHQ-15). Afterwards, 308 patients were studied in more detail using a diagnostic interview and a set of questionnaires. One year later, we were able to interview 277 participants a second time.

RESULT:

After 1 year, 48.8% of the respondents had a remitted SFD. The following variables proved to be significant predictors of MUS: current depressive episode, negative life events, number of MUS at baseline, attributional style, autonomic sensations and catastrophizing cognitions. The course of SFD could be predicted through current depressive or anxiety disorder, negative life events, functional disability and attributional style.

CONCLUSION:

Somatoform disorder has a favorable course. The predictors of the courses of SFD and MUS we found can be integrated into previous explanatory models. The coping with MUS or SFD can be seen as a mediating factor.
