A Study of Rheumatoid Arthritis Patients on Adalimumab to Evaluate Quality of Life Variables, Effects on Work Productivity and Functional Outcomes in Malaysia

The Health Assessment Questionnaire Short Form 36 (SF-36) determines participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 primarily contribute to the physical component summary score (PCS) of the SF-36. Items 5-8 primarily contribute to the mental component summary score (MCS) of the SF-36. Scores on each item are summed and averaged (range = 0 worst-100 best). The standard recall period is four weeks. Increases from baseline indicate improvement. Assessments were conducted at baseline and 6 months.

Time frame: Baseline and 6 months

The Health Assessment Questionnaire Visual Analog Scale (HAQ-VAS) is a patient-reported questionnaire designed to assess the presence or absence of arthritis-related pain and its severity. It consists of a doubly anchored, horizontal VAS, that is scored from 0 (no pain) to 100 (severe pain). Decreases from baseline indicate improvement. Assessments were conducted at baseline and 6 months.

Time frame: Baseline and 6 months

The Health Assessment Questionnaire - Disability Index (HAQ-DI) is a patient-reported questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. The minimal clinically important difference (MCID) defined for the HAQ-DI is ≥ 0.22. HAQ remission indicating normal physical function is defined by HAQ-DI \< 0.5. Negative mean changes from baseline in the overall score indicate improvement. Assessments were conducted at baseline and 6 months.

The Health Assessment Questionnaire Short Form 36 (SF-36) determines participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 primarily contribute to the physical component summary score (PCS) of the SF-36. Items 5-8 primarily contribute to the mental component summary score (MCS) of the SF-36. Scores on each item are summed and averaged (range = 0 worst-100 best). The standard recall period is four weeks. Increases from baseline indicate improvement. Assessments were conducted at baseline and 3 months.
