Cultural adaptation and cross-sectional psychometric testing. The aim of this study was to validate the Polish translation of the Roland-Morris Questionnaire (RMQ), which evaluates the functional level of activity of patients with discogenic low back pain with radicular radiation, caused by intervertebral herniation, according to category A1 in the Kirkaldy-Willis classification and Type QTF6 in classification Quebec Task Force. The main concern of patients with low back pain is the functional limitation that the symptoms cause. It is important to find a validation tool by means of which their functional level can be assessed. The RMQ was compared with MOS Short Form-36 Health Survey Questionnaire (SF-36), to pain scale, to depression scale, to functional scale that measures activities of daily living, and to measuring forward and side bending of the spine. Independently, two professionals made a translation and then two native speakers made a translation-back of the RMQ. Then 104 patients with lumbar disc herniation completed the RMQ, SF-36, VAS and FIR (ADL scale). The study group comprised 39 women and 65 men with an average age of 44 years. The significant correlation between the RMQ and other questionnaires was found. RMQ and SF-36 Physical, r = 0.47, P < 0.00001, RMQ and Pain, r = 0.462, P < 0.00001. Cronbach's alpha showed a value of 0.88 (scale 0-1). The correlation between severity of disease and quality of life, between bending of spine and quality of life, between depression and quality of life, and between activities of daily living and quality of life has been found. According to this study, the RMQ can be used as a valid tool in the assessment of the functional level of patients with lumbar pain and previous lumbar herniation. The RMQ is fast and easy to complete; it is valid, reliable, and sensitive. We recommend the questionnaire to be used in research of quality of life in low back pain.

In 1992 Von Korff and his co-workers developed a simple, brief questionnaire to assess the severity of chronic pain problems, the Chronic Pain Grade (CPG). The present study was conducted to analyse the psychometric properties of the translated German version of the CPG within a population of primary care back pain patients (n=130). Factor analysis yielded two factors which accounted for 72% of the variance of the questionnaire. The first factor 'Disability Score' (53.56% of the variance) revealed a good internal consistency (alpha=.88), the internal consistency of the second factor 'Characteristic Pain Intensity' was moderate (alpha=.68). The reliability of the whole instrument was good (alpha=.82). The CPG and its subscales show moderate to high relations with other instruments assessing the patient's disability (FFbH-R, Pain Disability Index PDI). Additionally weak to moderate but significant correlations were found between the CPG and other measures of gradin...
Study Design. Cross-cultural adaptation and psychometric testing. Objective. To conduct the cross-cultural adaptation of the Quebec Back Pain Disability Scale (QBPDS) and investigate its reliability and validity in patients with chronic low back pain (CLBP). Summary of Background Data. The QBPDS is one of the most commonly used scales to evaluate functional incapacity resulting from low back pain. Although measuring disability is an important outcome in physiotherapy care, there is no previous research relating to the cultural adaptation and psychometric testing of the QBPDS in the Portuguese-speaking population. Methods. The questionnaire was fi rst translated and back-translated in accordance with the published guidelines. The Portuguese version of the QBPDS was then pilot tested in a Portuguese sample of 40 patients with CLBP. Psychometric properties were evaluated in a new sample of 132 patients with CLBP. Exploratory factor analysis was performed to confi rm its unidimensionality. Reliability was evaluated through internal consistency and reproducibility, using the Cronbach α and intraclass correlation coeffi cient, respectively. Construct validity was assessed with correlations between the QBPDS and the Roland-Morris Disability Questionnaire and between the QBPDS and the visual analogue pain scale for convergent validity and pain localization for discriminative validity, using the Spearman correlation analysis and the Mann-Whitney test. Results. Exploratory factor analysis revealed the existence of one major factor that explains 52.1% of the variance. One-week test-retest reliability was 0.7, and internal consistency was 0.95. The QBPDS correlated strongly with the Roland-Morris Disability Questionnaire (0.62; P < 0.001), moderately with pain (0.38; P < 0.001), and shows capability to discriminate between patients with localized and referred pain ( U = 1218; P < 0.0005). Conclusion. The reliability and construct validity of the Portuguese version of the QBPDS are acceptable to assess functional status of Portuguese-speaking patients with CLBP.

Background: Chronic low back pain is a multidimensional syndrome affecting physical activity and function, health-related quality of life and employment status. The aim of the study was to quantify the cross-sectional and longitudinal validity of single measurement scales in specific construct domains and to examine how they combine to build a comprehensive outcome, covering the complex construct of chronic low back pain before and after a standardized interdisciplinary pain program. Methods: This prospective cohort study assessed 177 patients using the Short Form 36 (SF-36), the Multidimensional Pain Inventory (MPI), the Symptom Checklist-90-Revised (SCL-90-R), the Oswestry Disability Index (ODI), and 2 functional performance tests, the Back Performance Scale (BPS) and the 6-Minute Walking Distance (6MWD). The comprehensiveness and overlap of the constructs used were quantified cross-sectionally and longitudinally by bivariate correlations, exploratory factor analysis, and effect sizes. Results: The mean age of the participants was 48.0 years (+/− 12.7); 59.3% were female. Correlations of baseline scores ranged from r = − 0.01 (BPS with MPI Life control) to r = 0.76 (SF-36 Mental health with MPI Negative mood). SF-36 Physical functioning correlated highest with the functional performance tests (r = 0.58 BPS, 0.67 6MWD) and ODI (0.56). Correlations of change scores (difference of follow-upbaseline score) were consistent but weaker. Factor analysis revealed 2 factors: "psychosocial" and "pain & function" (totally explained variance 44.0-60.9%). Psychosocial factors loaded strongest (up to 0.89 SCL-90-R) on the first factor, covering 2/3 of the explained variance. Pain and function (ing) loaded more strongly on the second factor (up to 0.81 SF-36 Physical functioning at follow-up). All scales showed improvements, with effect sizes ranging from 0.16-0.67.
