Toward a multidimensional health assessment questionnaire (MDHAQ): Assessment of advanced activities of daily living and psychological status in the patient-friendly health assessment questionnaire format

The MDHAQ items overcome in large part the "floor effects" seen on the HAQ and MHAQ, and are useful to screen for problems with sleep, stress, anxiety, and depression in the "patient-friendly" HAQ format. These data support the value of completion of a simple 2-page patient questionnaire by each patient at each visit to a rheumatologist.
