INTRODUCTION: Juvenile Dermatomyositis (JDM) is the most common idiopathic inflammatory myopathy of childhood, it can be significant cause of long-term morbidity and it affects the childs development and quality of life. In recent years, there has been an increasing interest in parent/patient–reported outcomes (PRO) and involvement in the physicians monitoring of clinical course of disease, selection of therapeutic procedures, assessment of possible limitations and quality of life. Scientists recently developed a new multidimensional questionnaire JDMAR (Juvenile Dermatomyositis Assessment Report) for monitoring and assessing the health status in children with JDM that includes all main PRO. AIM: We want to contribute to further assessment of the JDMAR questionnaire validity and to examine its reliability and applicability in regular clinical practice. SUBJECTS AND METHODS: The study included children diagnosed with juvenile dermatomyositis who were treated at the Department of Pediatrics, Division of Immunology and Rheumatology, University Hospital Center Zagreb, in the period from 2012 to 2013. We analyzed 18 questionnaires and 18 standard medical forms. RESULTS: JDMAR completed by the patient or his parent provides reliable informations and doesn't differ from the doctor's objective assessment of disease status at the time of visit and disease progress since last visit. There was a significant difference between doctor's and patient's assessment of disease activity. CONCLUSION: JDMAR provides sufficient objective informations about disease status and disease progress. However, current value of disimilarities between the physician's and patient's evaluation of certain parameters, indicate a need for further improvement of the form of the qustionnaire as well as compatibility between the assessment of certain conditions by doctors and patients.
