Why are we doing this study?

There are a few widely available tools for assessing physical symptoms, particularly for use in studies that wish to examine somatic symptom disorders. However, the Physical Symptoms Questionnaire (PSQ) is a Dutch questionnaire which lists 51 physical symptoms often suffered in people with PSS. It asks people to indicate how much the symptoms have bothered them within the last week. The scale is currently only available in Dutch.

We wish to make the PSQ available for use in the English language, which could be particularly useful in studies wishing to develop and implement interventions to reduce symptoms and illness progression in patients with multiple conditions, and in clinical trials testing new treatments.
