The classification into subgroups has been considered a research priority in the treatment of low back pain. Whereas the Örebro Musculoskeletal Pain Screening Questionnaire - Short Form (ÖMPSQ-Short) Brazilian-Portuguese version is a prognostic screening tool that has not yet defined its predictive validity, the aim of this study is to examine the predictive validity of the ÖMPSQ-Short in Brazilian-Portuguese. The questionnaire will be applied in 150 patients with acute, subacute and chronic nonspecific low back pain (50 patients in each group) followed by a follow-up of six months to evaluate the prediction tool for considering the risk of chronic absence from work, pain and disability. Other instruments will be applied: the Roland Morris disability questionnaire, pain numerical rating scale, demographic issues related to work and an additional issue of absenteeism. To analyze the data, a T test or an ANOVA test will be held in order to compare variables between groups. 2x2 contingency tables will also be held. The predictive validity will be evaluated based on sensitivity and specificity and likelihood ratios. With this study, it will be possible to verify if the ÖMPSQ-Short instrument is capable of predicting the risk of chronicity considering the analysis of outcomes away from work, pain and disability over time, from the determination of predictive validity.
