The SF-36v2 is the latest version of SF36 which is a generic indicator of health status and has been applied in assessing outcomes of various health conditions in the general population. The instrument has been tested for validity and reliability. The SF 36 v2 measures and includes 8 subscales: physical functioning (PF), role limitations due to physical problems (RP), bodily pain, general health perception (GH), social functioning (SF), role limitations due to emotional problems (RE), vitality (VT), and mental health (MH). The score for each subscale range from 0-100 where higher scores indicate better conditions. A Malay version is available and has been shown to be reliable and valid for use[8] ( Appendix S1).
