Job requirements and physical demands (JRPD) questionnaire: cross-cultural adaptation and psychometric evaluation in Iranian Army personnel with chronic low back pain

Abstract Background Biomechanical risk factors have been identified as the main predisposing factor of chronic low back pain (CLBP), especially in Army personnel. The Job Requirements and Physical Demands (JRPD) questionnaire has been developed to assess the biomechanical exposures related to CLBP. Examining the biomechanical risk factors could prevent CLBP. This study aimed to translate and cross-culturally adapt the JRPD into Persian and assess its psychometric properties among Iranian male Army personnel with CLBP. Methods In this cross-sectional study, the content validation of the JRPD was assessed after translating to Persian. The Persian JRPD was administered to 198 male Army personnel with CLBP, with an interval of 7 days, to assess test-retest reliability, including Cronbach’s α, intraclass correlation coefficients (ICC), standard error of measurement (SEM), and minimal detectable change at 95% confidence interval (MDC95%). Scores of the Persian JRPD were correlated with the scores of visual analog scale (VAS), Borg’s category-ratio (CR10) scale, general health questionnaire-28 (GHQ-28), and physical functioning (PF1 and PF2) subscale of the 12-item short-form health survey (SF-12) to assess convergent validity using Spearman correlation for a priori hypotheses. Results The Persian JRPD had good content validity evidenced by the higher content validity index (> 0.70). The questionnaire had a significant positive negligible to weak correlation with the VAS (rho = 0.27; p < 0.001), Borg’s CR10 scale (rho = 0.19; p = 0.009), and the total score of GHQ-28 and its domains (rho ≤0.34; p < 0.05); and significant negative weak correlation with PF2 (rho = − 0.27; p < 0.001) and significant negative moderate correlation with PF1 (rho = − 0.35; p < 0.001), thus confirming the priori hypotheses (89%, 8/9). The internal consistency and ICC (α = 0.91; ICC = 0.80) were highly adequate, with SEM and MDC95% of 7.91 and 21.3 respectively. Conclusions The JRPD was successfully adapted into Persian and had adequate psychometric properties in terms of content and convergent validity, internal consistency, and test-retest reliability. The questionnaire is found useable to assess the CLBP-related biomechanical exposures in Iranian male Army personnel.

Abstract Background: Biomechanical risk factors have been identified as the main predisposing factor of Chronic Low Back Pain (CLBP), especially in Army personnel. The Job Requirements and Physical Demands (JRPD) questionnaire has been developed to assess the biomechanical exposures related to CLBP. Examining the biomechanical risk factors could prevent CLBP. This research was designed to cross-cultural adaptation and the psychometric properties of the Persian version of the Job Requirements and Physical Demands (JRPD) questionnaire among Iranian Army personnel with Chronic Low Back Pain (CLBP).Methods: In this non-experimental and methodological designed study, the content validation of the JRPD was performed after translating to Persian. The Persian JRPD was administered to 198 Army personnel with CLBP, with an interval of seven days, to assess test-retest reliability. Scores of the Visual Analog Scale (VAS), Borg's Category-Ratio (CR10) scale, General Health Questionnaire-28 (GHQ-28), and two Physical Functioning (PF1 and PF2) items of the 12-item Short Form survey (SF-12) were recorded to estimate the correlation with the Persian JRPD.Results: After content validation, the number of items in the Persian JRPD remained unchanged. Persian JRPD was correlated with VAS (r = .27; p < .001), Borg's scale (r = .19; p < .009), GHQ-28 (r = .31; p < .001), PF1 (r = -.35; p < .001), and PF2 (r = -.27; p < .001). Also, test-retest reliability and internal consistency values were found to be .80 and .91, respectively.Conclusion: The Persian version of the JRPD is a valid questionnaire with good reliability when applied to Iranian Army personnel with CLBP.

AbstractBackground and aimsBased on a transdiagnostic approach, this study assesses the impact of cognitive and emotional processes (difficulties in emotional regulation, impulsiveness, rumination and somatosensory amplification) on the psychological risk factors of chronic low-back pain.MethodsThe study was carried out with 256 patients with chronic low-back pain. All the variables were assessed through a booklet of 10 validated questionnaires. Multiple regression analysis and moderation analysis were performed.ResultsPredictors included in multiple regression models explain 3%-42% (adjusted R2) of the variance in psychological risk factors. Moreover, analyses reveal a significant moderator effect of somatosensory amplification on the link between fear-avoidance beliefs linked to work and pain intensity (F(3;250) = 12.33; p = .00), of somatosensory amplification and brooding on the link between depression and functional repercussions (FR) on everyday life (F(3;252) = 13.36; p = .000; F(1;252) = 12.42; p = .00), of the reflection dimension of rumination on the link between the helplessness dimension of catastrophizing and FRs on sociability (F(3;252) = 37.02; p = .00). There is also a moderation analysis with a significant trend concerning the lack of emotional awareness and the difficulties in controlling impulsive behaviours.ConclusionsOur results indicate an important role of some dimensions of difficulties in emotional regulation, somatosensory amplification and rumination in the increase in negative affects and dysfunctional beliefs, and in the links between those psychological risk factors and pain/disability.ImplicationsThis study identifies some cognitive and emotional dysregulations substantially involved in work-related chronic pain. This contribute to put in place psychotherapeutic protocols to tackle these deficits and dysregulations in a relevant way.

Abstract Background Empirical evidence that identifies the pelvic asymmetry in which movement plane that contribute to non-specific chronic low back pain (NCLBP) is currently lacking. Objective To establish the reliability of the Global Postural System (GPS) in assessing pelvic asymmetry and identify the association between pelvic asymmetry parameters and the occurrence of NCLBP in young adults. Design A cross-sectional, regression study. Methods People who aged between 18 and 30 and were diagnosed with NCLBP were recruited. Healthy individuals who were matched for age, gender, and education level were recruited as controls and for the reliability analysis. Reliability was assessed by the ICC (3, k), standard error and minimal detectable difference. Bivariate correlation analysis and logistic regression analysis were used to determine the risk factors. Results Twenty-eight healthy participants and 28 people with NCLBP were recruited. Moderate to excellent ICCs were observed for the inter-rater and intra-rater reliability of most postural parameters. The bivariate correlation analysis indicated that age, body mass index and pelvic asymmetry parameters were related to the occurrence of NCLBP. Pelvic angle asymmetry (odd ratio=1.17), and asymmetry of the distance between the posterior superior iliac spine and the floor (odd ratio=1.21) were significant risk factors of NCLBP. Limitation This study did not explore the causal relationship between pelvic asymmetry in the sagittal plane/pelvic asymmetry in the transverse plane and the occurrence of NCLBP. The interpretation of the results may not be generalized beyond the sample population. Conclusions The GPS is a reliable method to assess pelvic asymmetry in a clinical setting. The pelvic asymmetry parameters obtained from the GPS are likely to assist in the early identification of the potential occurrence of NCLBP.
