Author summary

The Short Musculoskeletal Function Assessment (SMFA) questionnaire consists of a thirty-four item “dysfunction index”, assessing patient function, and a twelve item “bother index” assessing how much a patient is bothered by functional problems. The SMFA questionnaire demonstrated excellent internal consistency. Content validity for both indexes was supported with very little skew, few ceiling effects and no floor effects. The SMFA was significantly correlated to physicians' ratings of patient function and to standard clinical measures.
