    Attention COACH STUDY participants:

    The principal investigators of the study request that you use the official version of the modified score here.

    Patient Activity Scale (PAS) for RA

    Quantifies severity of rheumatoid arthritis (RA) using patient-reported symptoms.

    INSTRUCTIONS

    Note: the PAS II is an alternative to the PAS. PAS II uses a slightly different questionnaire with fewer questions than the original PAS, though the overall accuracy of the two is the same.

    When to Use
