The Croatian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR)

Area of Science:

• Pediatric Rheumatology
• Clinical Assessment Tools
• Health Outcomes Research

Background:

• Juvenile idiopathic arthritis (JIA) requires comprehensive assessment tools.
• The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a novel parent/patient-reported outcome measure.
• Cross-cultural adaptation and validation are crucial for global applicability.

Purpose of the Study:

• To perform the cross-cultural adaptation and validation of the Croatian versions of the JAMAR (parent and patient).
• To assess the psychometric properties of the JAMAR in a Croatian pediatric population with JIA.
• To establish the JAMAR's suitability for clinical practice and research in Croatia.

Main Methods:

• Cross-cultural adaptation and translation of the JAMAR into Croatian.
• Reading comprehension testing with 10 JIA patients and parents.
• Validation study involving 100 JIA patients and 100 healthy children.
• Psychometric evaluation including reliability, validity, and assumption testing.

Main Results:

• The Croatian JAMAR demonstrated good reading comprehension.
• All JAMAR components showed satisfactory psychometric performance.
• The tool effectively discriminated between JIA patients and healthy children.
• High reliability and validity were confirmed for the Croatian JAMAR.

Conclusions:

• The Croatian version of the JAMAR is a valid and reliable tool for assessing children with JIA.
• The JAMAR is suitable for routine clinical practice and clinical research in Croatia.
• This validated tool enhances the multidimensional assessment of JIA in the Croatian pediatric population.
