The Medical Outcome Study Short Form 36 measures three major health attributes (functional status, wellbeing, overall health) in eight subscales. These include PF (Physical function), RP (role limitations due to physical health), BP (bodily pain), GH (general health), VT (vitality), SF (social function), RE (role limitations due to emotional health), and MH (mental health). For each variable item scores are coded, summed, and transformed to a scale from 0 (the worst possible health state) to 100 (the best possible health state).
