Predictive ability of a modified Orebro Musculoskeletal Pain Questionnaire in an acute/subacute low back pain working population.

摘要

The original 'Orebro Musculoskeletal Pain Questionnaire' (original-OMPQ) has been shown to have limitations in practicality, factor structure, face and content validity. This study addressed these concerns by modifying its content producing the 'Orebro Musculoskeletal Screening Questionnaire' (OMSQ). The OMSQ and original-OMPQ were tested concurrently in acute/subacute low back pain working populations (pilot n = 44, main n = 106). The OMSQ showed improved face and content validity, which broadened potential application, and improved practicality with two-thirds less missing responses. High reliability (0.975, p < 0.05, ICC: 2.1), criterion validity (Spearman's r = 0.97) and internal consistency (alpha = 0.84) were achieved, as were predictive ability cut-off scores from ROC curves (112-120 OMSQ-points), statistically different OMSQ scores (p < 0.001) for each outcome trait, and a strong correlation with recovery time (Spearman's, r = 0.71). The six-component factor structure reflected the constructs originally proposed. The OMSQ can be substituted for the original-OMPQ in this population. Further research will assess its applicability in broader populations.
