Online published on 3 April, 2018. Abstract This study investigated the relationship among pain, functional disability, kinesiophobia and health-related quality of life (HRQoL) in patients with work-related low back pain (WRLBP). Eighty-six individuals with WRLBP participated in the study. Pain intensity, functional disability, kinesiophobia and HRQoL were assessed using Quadruple Visual Analogue Scale, Oswestry Low Back Pain Disability Questionnaire, Tampa Scale of Kinesiophobia and WHO-QoL BREF respectively. Data were analyzed using descriptive statistics, Pearson's correlation test and stepwise regression analysis with alpha level set at 0.05. The mean age of the participants was 34.6 ± 6.88 years. There were significant positive correlations between pain intensity and each of functional disability and kinesiophobia (r =0.605, 0.589, p <0.001) and negative correlation with HRQoL (−0.371.p =0.001). Functional disability showed a significant inverse relationship with HRQoL and a significant strong positive correlation with kinesiophobia scores respectively (−0.487, 0.754, p < 0.001) while HRQoL showed a significant inverse relationship with each of pain intensity (−0.371, p = 0.001) functional disability (−0.487, p < 0.001) and kinesiophobia scores (−0.505, p < 0.001). Stepwise regression analyses indicated that pain intensity is the most significant predictor of functional disability (R2 = 0.308), kinesiophobia (R2= 0.339) and HRQoL (R2 = 0.158). Pain intensity was the most significant predictors of physical function, kinesiophobia and HRQoL in patients with WRLBP.
