Plain English Summary
Background and study aims
Somatic symptom disorders are mental disorders characterized by physical symptoms that suggest physical illness but which cannot be explained fully by a general medical condition. A new brief psychological therapy may help people worry less. The aim of this study is to test how people find this therapy and whether it works. The researchers want to see whether it reduces worry, especially worries about health and illness. If it is shown to work then it will be possible to use the therapy in NHS services.
Who can participate?
Adults meeting criteria for somatic symptom disorders
What does the study involve?
Participants receive a ‘worry intervention’ in 6 sessions over 8 weeks, either at home or at the GP surgery. The worry reduction strategies include psycho-education about worry, reviewing of beliefs about worry, increasing awareness of the initiation of worry and identification of individual triggers, use of worry periods, substituting problem-solving in place of worry and relaxation exercises. There are homework exercises between sessions. At the end of the study, participants are invited to take part in another interview to talk about their experience of the therapy sessions and suggest improvements. Participants are paid £15 for each assessment session, and travel expenses are paid.
What are the possible benefits and risks of participating?
It is hoped that participants benefit from the opportunity to engage in the worry intervention. The main possible burden is time taken to complete the questions.
Where is the study run from?
South East England (UK)
When is the study starting and how long is it expected to run for?
June 2014 to August 2015

Somatic symptom disorder
Patients with Somatic Symptom Disorder will be offered 6 sessions of individual manualised psychological intervention focussed on worry. A control group is not included in this design.
The worry intervention will be provided in 6 sessions over 8 weeks. Intervention sessions will take place at home or at the participant's GP surgery, to minimise travel and burden for the participant. The worry reduction strategies included are indicated in the anxiety literature to be effective at reducing worry and do not challenge the illness interpretation. The main techniques are psycho-education about worry, reviewing of beliefs about worry, increasing awareness of the initiation of worry and identification of individual triggers, use of worry periods, substituting problem-solving in place of worry and relaxation exercises. Homework exercises are set between sessions. Written information is provided for patients (see appendix B). With patients’ consent, sessions will be taped for assessment of adherence and for competence.
At the end of sessions, a consultation letter will be developed with the patient and shared with the patients’ referring clinician and their general practitioner.
Primary outcome measures
Health Anxiety Inventory (Salkovskis, Rimes, Warwick & Clark, 2002). Assessments will take place at baseline and 8 weeks.
Secondary outcome measures
1. Intolerance of Uncertainty Questionnaire (Freeston, Rheaume, Letarte, Dugas & Ladouceur (1994)
2. Penn State Worry Questionnaire (Meyer, Miller, Metzger & Borkovec, 1990)
Hospital Anxiety and Depression Scale (Zigmond & Snaith, 1983)
3. EQ-5D (Rabin & de Charro, 2001)
4. Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS, Tennant, Hiller, Fishwick, Platt, Weich, Parkinson et al, 2007)
5. A question around the acceptability of a referral for psychological therapy, developed for this study
6. Number of attendences at A&E,
7. Outpatients and General Practice will also be recorded
8. New physical diagnoses will also be noted.
The scales will provide comparative measures of symptoms, functioning and well being with some estimate of resource utilisation.
Assessments will take place at baseline and 8 weeks.
