This study was designed to evaluate adalimumab therapy in Malaysia on participants' Quality of Life (QoL) using non-invasive epidemiological methods like the Health Assessment Questionnaire - Disability Index (HAQ-DI), the Health Assessment Questionnaire Visual Analog Scale (HAQ-VAS), and the Health Assessment Questionnaire Short Form 36 (SF-36). The primary objective of the study was to evaluate the changes in QoL outcomes in anti -TNF naïve Malaysian RA patients after 6 months of adalimumab treatment. The secondary objectives of this study were to evaluate the changes on QoL outcomes after 1 month and 3 months of adalimumab treatment; and provide an assessment of the safety and tolerability of adalimumab in anti TNF naïve Malaysian Rheumatoid Arthritis patients.
