[Depression and rheumatism: options for measuring depression]

The importance of depressive diseases in the treatment of rheumatism patients cannot be denied. It is well-known from publications in the English speaking literature that the proportion of depressive diseases lies between 10% and 45% in patients with rheumatoid arthritis (RA). However, clearly increased numbers can also be seen in a direct comparison with corresponding prevalence rates in the normal population for other diseases included in the category of rheumatism.

This manuscript focusses on the possibilities and challenges in measuring states of depressive mood that might serve as an indicator of depressive diseases in the context of treatment of rheumatism.

A search of the current literature was carried out and the results were evaluated.

Starting from appropriate background knowledge, the current state of science is discussed while subsequently taking a closer look at a choice of internationally recognized assessment tools which are feasible for use in rheumatology. Finally, this overview is accompanied by hints for hands-on practice and suggestions on how to respond to conspicuous test results indicative of a depressive mood.

The potential benefits of appropriate screening with measurement instruments are considered to be high for rheumatism patients. The measurement tools presented must be suitably selected for the individual purpose and for each rheumatology institution. In view of test application consideration must be given not only to the total score but also to the individual responses to test items. In cases of conspicuous test results the further approach must be agreed together with the patient and by choosing adequate treatment options for the situation. In cases of acute suicidal tendencies acceptance, care and support are of key importance, while the precautionary presentation in a specialist clinic must be initiated.
