Many workers in sick-leave present difficulties to Return to Work (RTW). Therefore, it is important that Occupational Health professionals evaluate and understand the Obstacles to RTW in order to help patients to obtain coping strategies. Obstacles to Return-to-Work Questionnaire (ORQ) has been used in order to evaluate physical and psychological risk factors for pain and disability at workplace. In Brazil there are few studies about this issue and the ORQ have been translated and culturally adapted in order to offer a valid and reliable tool. The aim of this study is to evaluate the psychometric properties of the Brazilian version of the ORQ.


The study was carried out in physiotherapy clinics and in the Reference Center on Occupational Health in Campinas/Brazil. The participants were workers over 18 years old that presented musculoskeletal disorders diagnosis, and who were away from work due to this disorders. The validity was evaluated by convergent construct technique. The ORQ results were compared with other questionnaires that addressed similar constructs: WhoQol, Need for Recovery Scale (NFRS), Job Stress Scale (JSS), Fear Avoidance Beliefs Questionnaire (FABQ), Occupational Stress Indicator (OSI), Pain Scale and Survey of Pain Attitudes (SOPA). The reliability was evaluated by internal consistency through Cronbach’s Alpha coefficient and by stability method (test-retest) through Intraclass Correlation coefficient (ICC).The significance level adopted was p-value <0.05.


The sample size of this study was 301 subjects (response rate 94.3%). The mean age was 45.0 (9.9) years.They belonged to several kinds of jobs: 48.8% physical work demand (metallurgical, general services, etc), 25.5% mental work demand (administrative area) and 25.9% mixed work demand (health sector). The Spearman correlation coefficients of the ORQ domains varied between -0.49 to 0.85. The Cronbach’s Alpha coefficient varied from 0.72 to 0.89 for the majority of ORQ’s domains, except to “Worry due to Sick Leave”=0.44 and “Family situation and support”=0.61. The ICC varied between 0.68 to 0.90.


Brazilian version of the ORQ presented appropriate convergent construct validity and confiability to the studied population. However the structural validity should also be carried out.
