Background: Physical therapy is one of the most proposed services to the patients, who suffer from low back pain (LBP). Modern health care system is currently oriented towards multidisciplinary approach, considering the importance of both physical and psychosocial factors. Therefore, in order to provide early and targeted intervention, identification of patients at risk of developing chronic LBP using screening tools that combine multiple predictors is recommended. Among the available instruments, the Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ) is a relevant 25-item tool that briefly evaluates several factors involved in the transition from acute to chronic back pain. Nowadays, clinicians can choose between various formats of ÖMPSQ, which were cross-culturally adapted in many languages. However, for French speaking countries only the full version is validated.
Purpose: The objectives of this study were:
1) to adapt the short ÖMPSQ format (10 items) in French and investigate its outcomes with respect to pain, function and work absence and
2) to explore the potential of short- ÖMPSQ psychosocial sub-score in stratification of patients with acute and subacute low back and neck pain.
Methods: The data for this prospective validation study of the short ÖMPSQ were extracted from the full version filled out by patients at the first contact and 6 months later. Analysis of predictive validity, the sensitivity and specificity of the full and short- ÖMPSQ total scores, a new psychosocial ÖMPSQ score, and the two expectation items were done by calculating the receiver operating characteristics (ROC) curves and the area under the ROC curves (ROC AUC) for three outcomes: pain, function and work absence.
Results: Seventy-three participants were included in this study (average age 42.2 ± 10.7 years; 33 females). Among them 47% had lumbar pain only, 8% had cervical pain and 45% had pain on more than one site. There was a high correlation between the total scores of the full- and short-ÖMPSQ (r = 0.781 at inclusion; 0.771 after 6 months). Discriminative ability was very similar for both versions, showing better results for pain (ROC AUCfull=0.93; ROC AUCshort=0.89) than for function (ROC AUCfull=0.88; ROC AUCshort=0.82) and work absence outcomes (ROC AUCfull=0.74; ROC AUCshort=0.64). Analogous results were obtained for two expectation items combination (Items7+8 of the short-ÖMPSQ) with ROC AUC for pain, function and work absence outcomes respectivly of 0.835, 0.728 and 0.668. We proposed several cut-off points for each outcome in order to identify three risk groups (low, medium and high), which mainly depended on psychosocial sub-score.
Conclusion(s): These data indicate that the French short-ÖMPSQ as a tool for screening for chronicity risk in patients with acute LPB is as good as the long version of this questionnaire. Particularly, the psychosocial ÖMPSQ sub-score revealed the best patient risk classification potential among all scores, especially for work absenteeism outcome.
Implications: The short OMPSQ tool could be recommended for use in physical therapy practice, depending on available time and resources in the clinic. When considering treatment strategies, we suggest implementing the ÖMPSQ psychosocial sub-score to stratify the patients into three risk groups (low, medium and high).
