[The rating box--a new instrument for ambulatory detection of subjective variables]

For the acquisition of subjective variables in outpatients and inpatients, a new device--the Rating Box--has been designed. The Rating Box provides a standardized, date- and time-logged documentation of symptoms by the patient and rapid transfer of data to a personal computer. The simultaneous acquisition of several symptoms using different types of scales is possible. The acoustic alarm of the Rating Box reminds the patient to enter data at preselected times. The device is easy to handle, even by older patients, and has been successfully tested in the acquisition of pain variables in patients with a variety of painful conditions.
