RESUMEN
INTRODUCTION: The treat-to-target serum uric acid approach is recommended in local and international guidelines on gout management. Instruction for initiation and dose escalation for urate lowering therapy may cause confusion to the patient. Our aim was to develop and validate Gout Treat-To- Target booklet to aid in patient education. MATERIALS AND METHODS: A content development team which consisted of three consultant rheumatologists developed the booklet. Content validation was performed by a panel of evaluators consisted of eleven physicians (four consultant rheumatologists, two clinical specialists, and five medical officers), who were involved in gout management. Face validation was performed by ten patients with gout. RESULTS: Item-Content Validity Index ranged from 0.9 to 1 with regards to relevancy, clarity, ambiguity and simplicity. Side effects of uricosuric agents were added to the draft based on an evaluator's comment. Item-Face Validity Index was 1, which indicated that all patients were in 100% agreement with all items. CONCLUSION: We developed and validated our Gout Treat-to- Target booklet. There was high agreement in I-FVI and I-CVI among physicians and patients.
