The questionnaires contain questions to the following themes.

• Disease activity
• Disability in everyday life
• General health
• Quality of life
• Social and professional environment
• Managing disease

The questionnaires on quality of life partly contain very similar questions. On one hand, this is because we use internationally accepted and validated questionnaires. It is important to read each questions closely, because in most cases, even if questions look similar, they ask for a distinct information.
