| Study acronym | PISO |
| Study objectives | Patients with medically unexplained physical symptoms are 'high utilizers' of the health care system with high psychiatric co-morbidity and severe impairments in quality of life (QoL). There is preliminary evidence that psycho-dynamic-interpersonal therapy (PIT) is beneficial as it reduces the intensity of physical symptoms and increases quality of life. The trial interventions so far lacked generalizability over a larger clinical spectrum of disabling somatoform symptoms. We developed a multi-centre two-arm randomized controlled trial with a primary end point and follow-up after one year. PISO has two new aspects: 1. PISO uses a diagnostic category that is independent of the type of currently dominant symptom and therefore serves as a common point of reference 2. PISO uses a manualized psychotherapeutic intervention that is adapted to the specific lead symptom in the beginning, but later on emphasizes more general aspects of experiencing 'unexplained' physical symptoms across single functional syndromes and somatic specialities In the trial, we test a bio-psycho-social model of change including psychobiological parameters like heart rate variability and prefrontal/limbic neural activations. If the intervention tested in PISO proves to be efficacious as compared to enhanced medical care it will be useful as an economic and versatile tool that is applicable in cooperation with psychosomatic medicine across a range of somatic specialities. |

| Primary outcome measure | SF-36 Physical Component Summary (PCS): In patients with multi-somatoform disorder, symptom-related incapacity is best captured with the PCS. The German version of the SF-36 health survey short form has been validated and is sensitive to change, the assumed effect size of 0.50 is clinically relevant. |
| Secondary outcome measures | 1. IPQ, Brief Form: The brief form of the 'Illness Perception Questionnaire' (BIPQ, Broadbent et al. in submission) provides a quantitative measure of the components of illness representations that has been shown in treatment trials to be sensitive to change. The German version was developed and validated by Gaab (unpublished manuscript). 2. PHQ-D: The 'Patient Health Questionnaire', German version (PHQ-D) is a brief self-report measure for anxiety, depression and other mental disorders. Criterion validity was established with respect to diagnostic gold standards and the PHQ has proven to be a responsive and reliable measure of depression treatment outcome (Löwe et al. 2004). 3. SOMS-7: Seven-day version of the 'Screening for Somatoform Symptoms'. A 53-item instrument for the evaluation of treatment effects in somatoform disorders, covering all somatic symptoms occurring in somatization disorder, according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and International Statistical Classification of Diseases and Related Health Problems - tenth revision (ICD-10) (Rief and Hiller 2003). 4. Whiteley-Index-7: The seven-item version of the Whiteley Index, an established hypochondriasis scale first described by Pilowsky, was developed and validated by Christensen et al. (2003) specifically to assess treatment effects. 5. LEAS: The 'Levels of Emotional Awareness Scale' (Lane and Schwartz 1987, German version: Subic-Wrana et al. 2002) is a projective text based measure that assesses the capacity to describe own emotional experience and the one assumed in others. It will be used as a predictor variable conceptually related to the theory of change assumed for the treatment intervention. 6. Heart rate variability (HRV): HRV measurement and analysis equipment will be present at each centre. Time-domain (RMSSD) and frequency domain (HF-HRV) analysis will be performed during a stress test with the emotional stroop paradigm. |
