Factor analyses for the Örebro Musculoskeletal Pain Questionnaire for working and nonworking patients with chronic low back pain

Abstract BACKGROUND: The Örebro Musculoskeletal Pain Questionnaire (ÖMPQ) assesses the psychosocial factors in people with complaints of musculoskeletal disorders and predict those likely to develop persistent symptoms. OBJECTIVE: To culturally-adapt and assess the validity of the ÖMPQ in an Arabic population with low back pain (LBP).METHODS: The ÖMPQ was translated into Arabic. Eighty-four patients completed the questionnaires at baseline, 2 days later, and 3 months follow-up. The test-retest reliability, interclass correlation coefficient (ICC), specific agreement, predictive validity and content validity were assessed.RESULTS: For construct validity, the Arabic ÖMPQ (A-ÖMPQ) had a moderate (r ≥ 0.3, < 0.5) to high (r ≥ 0.5) correlation with pain, disability, fear-avoidance and catastrophizing questionnaires. The test-rest reliability showed was high ICC2,1=0.92 (95% CI: .83 - .96). The A-ÖMPQ score at baseline can significantly predict disability at 3 months F(1,82)=33.87, p<.01; R2=.29.CONCLUSIONS: The translation of the A-ÖMPQ into Arabic was successful. The A-ÖMPQ showed very good psychometric properties, and thus can be used to evaluate the psychosocial factors amongst patients with LBP.

Long Term Prognosis

BackgroundWe investigated the influence of sleeplessness and number of insomnia symptoms on the probability of recovery from chronic low back pain (LBP), and the possible interplay between sleeplessness and co-occurring musculoskeletal pain on this association.MethodsThe study comprised data on 3712 women and 2488 men in the Norwegian HUNT study who reported chronic LBP at baseline in 1995–1997. A modified Poisson regression model was used to calculate adjusted risk ratios (RRs) for the probability of recovery from chronic LBP at follow-up in 2006–2008, associated with sleep problems and co-occurring musculoskeletal pain at baseline.ResultsCompared with persons without sleeplessness, persons who often/always experienced sleeplessness had a lower probability of recovery from chronic LBP (RR 0.65, 95% CI 0.57 to 0.74 in women and RR 0.81, 95% CI 0.69 to 0.95 in men). Although there was no clear evidence of statistical interaction between sleeplessness and co-occurring musculoskeletal pain, women and men who often/always experienced sleeplessness and had ≥5 additional chronic pain sites had RRs of recovery of 0.40 (95% CI 0.33 to 0.48) and 0.59 (95% CI 0.45 to 0.78), respectively, compared with persons without sleeplessness and 1–2 chronic pain sites.ConclusionThese findings suggest that preventing or reducing sleep problems among people with chronic LBP may have the potential of improving the long-term prognosis of this condition, also among those with several additional pain sites.

Health State Utilities

Abstract Background Musculoskeletal disorders are a leading cause of disability adjusted life years (DALY) in the world. We aim to describe the prevalence and to compare the DALYs and loss of health state utilities (LHSU) attributable to common musculoskeletal disorders in Chile. Methods We used data from the Chilean National Health Survey carried out in 2016–2017. Six musculoskeletal disorders were detected through the COPCOPRD questionnaire: chronic musculoskeletal pain, chronic low back pain, chronic shoulder pain, osteoarthritis of hip and knee, and fibromyalgia. We calculated the DALY for each disorder for 18 sex and age strata, and LHSU following an individual and population level approaches. We also calculated the fraction of LHSU attributable to pain. Results Chronic musculoskeletal pain disorder affects a fifth of the adult population, with a significant difference between sexes. Among specific musculoskeletal disorders highlights chronic low back pain with the highest prevalence. Musculoskeletal disorders are a significant cause of LHSU at the individual level, especially in the case of fibromyalgia. Chronic musculoskeletal pain caused 503,919 [283,940 - 815,132] DALYs in 2017, and roughly two hundred thousand LSHU at population level, which represents 9.7% [8.8–10.6] of the total LSHU occurred in that year. Discrepancy in the burden of musculoskeletal disorders was observed according to DALY or LSHU estimation. The pain and discomfort domain of LHSU accounted for around half of total LHSU in people with musculoskeletal disorders. Conclusion Chronic musculoskeletal pain is a major source of burden and LHSU. Fibromyalgia should deserve more attention in future studies. Using the attributable fraction offers a straightforward and flexible way to explore the burden of musculoskeletal disorders.
