Study objectivesTo determine whether a newly developed specific psychosomatic short-term group intervention for patients with functional/ somatoform complaints can effectively be implemented in primary care and leads to improvements in patients' outcomes.
Ethics approval(s)Ethics Committee of the Medical Faculty, University of Heidelberg. Approved on 19 March 2007 (ref: S-074/2007)
Health condition(s) or problem(s) studiedFunctional/ somatoform complaints and disorders
InterventionAll GPs receive a training programme in early diagnosis and management of functional/ somatoform complaints in primary care that has already been evaluated.

In addition, a manualised specific psychosomatic short-term group intervention for patients with functional/ somatoform complaints in primary care will be developed. It integrates psychodynamic-interpersonal and cognitive-behavioural elements and emphasizes psychoeducation and resource activation. By experiencing the group process, new perspectives on awareness, self-reference, emotional involvement and relationship patterns shall be opened.

The GPs of the intervention group are trained to conduct the new group intervention in their offices together with a psychosomatic specialist. In each practice of the intervention group the participating patients are treated with the new short-term group intervention. The group format is 10 weekly sessions of ninety minutes each and one booster session. GPs and psychosomatic specialists are supervised in conducting the groups. Patients in the control group receive enhanced medical care.

Primary outcome measurePhysical quality of life (Physical Component Summary [PCS] of the Short From-36 Health Survey [SF-36]) will be assessed before the intervention and 3 and 9 months after the intervention.
Secondary outcome measuresPatients' characteristics:
1. Mental comorbidity (Patient Health Questionnaire, German version [PHQ-D]), assessed before the intervention and 3 and 9 months after the intervention.
2. Functional impairment (PHQ-D, SF-36) , assessed before the intervention and 3 and 9 months after the intervention.
3. Mental quality of life (Mental Component Summary [MCS] of the SF-36), assessed before the intervention and 3 and 9 months after the intervention.
4. Health related quality of life (EQ-5D), assessed before the intervention and 3 and 9 months after the intervention.
5. Health care utilization, disability days, direct and indirect medical costs (German version of the Client Sociodemographic and Service Receipt Inventory [CSSRI]), assessed before the intervention and 9 months after the intervention.
6. Illness perception (Illness Perception Questionnaire [IPQ], Brief Form), assessed before the intervention and 3 and 9 months after the intervention.
7. Control beliefs (Illness and Health Locus of Control Questionnaire [KKG]), assessed before the intervention and 3 and 9 months after the intervention.
8. Emotional awareness (Toronto Alexithymia Scale [TAS-20]), assessed before the intervention and 3 and 9 months after the intervention.

Additionally the group process will be monitored from the perspective of the patients and the therapists.

The training programme and its effects on GPs' competence will be evaluated, including difficulty experienced by the physician in the physician-patient relationship (Difficult Doctor-Patient Relationship Questionnaire [DDPRQ-10]). The evaluation will be carried out immediately after the training course, immediately after the group intervention and 9 months after the group intervention.

Target number of participantsAiming at 242 (2 x 121) patients and assuming a drop-out rate of 20% and further 20% loss to follow-up, initially 378 (2 x 189) patients should be enrolled in the trial.
Key inclusion criteria1,112 General Practitioners (GPs) within 45 minutes outreach around Heidelberg are invited to take part in the trial by letter. The first 36 of them who agree to participate are included in the trial. They are stratified by group experience (yes/no) and training in Psychosocial Primary Care (PPC) (yes/no) and randomly assigned to the intervention or control group.

The GPs recruit patients to participate in the trial according to following inclusion criteria:
1. The presence of functional/somatoform complaints (persistent [at least 6 months] bodily complaints for which no sufficient organic explanation can be found)
2. The somatoform disorder is the main treatment issue (co-morbidities are allowed)
3. Indication for short-term group intervention
4. Age 18-70 years
5. Distance from the practice to the place of residence not more than around 30 kilometers
6. Written informed consent

Patients selected by the GPs are additionally assessed for somatoform disorders by the Patient Health Questionnaire (PHQ-15) and the Whitely-7 (WI-7).

GPs' selection of patients is examined separately to assess its representativeness.
Key exclusion criteria1. Ongoing psychotherapy
2. Substance abuse (benzodiazepins, alcohol, drugs)
3. Severe psychiatric disorder: major depression (PHQ-9), psychosis, dementia or neurodegenerative disorders
4. Impairment by severe acute organic disease (Karnofsky index lower than 70%)
