The GEPARD questionnaire («GErman Psoriasis ARthritis Diagnostic questionnaire») was developed to screen psoriasis patients for the presence of psoriatic arthritis based on the clinical presentation. The screening questionnaire can be easily completed by the patients themselves in the practice. At 4 or more points, the specificity of psoriatic arthritis is 89%.
