Functional Status Index defines function as including distinct but related dimensions: the degree dependence, difficulty and amount pain experienced in performing specific activities daily living. A total 149 adults with rheumatoid arthritis were studied. Exploratory factor analyses scores on 18 across hypothesized dimensions yielded following categories: gross mobility, hand activities, personal care, home chores interpersonal activities. resultant indexes achieve internal consistency levels ranging from 0.66 to 0.91 all 1 category. Average test-retest interobserver values range 0.65 0.81. Levels generally equal or surpass reliability. findings suggest that it is feasible quantify level using self-report methods. recommended for use investigations where changes are interest.
