Therefore, the objective of this present research was to examine the relationship between facets of mindfulness and the mentioned outcomes in individuals with musculoskeletal pain (MSP), including an extensive population of patients. participants and procedure In a cross-sectional research, 200 patients with chronic MSP were selected from northern Iran by the consecutive sampling method and were assessed through the Five Facet Mindfulness Questionnaire (FFMQ), Visual Analogue Scale (VAS), 24-item Roland Morris Disability Questionnaire (RMDQ-24), 17-item Tampa Scale of Kinesiophobia (TSK-17), and the Coping Strategies Questionnaire-Catastrophizing subscale (CSQ-CAT). results Results were obtained via multivariate hierarchical regression analyses after adjusting for the effects of demographic variables, revealing that higher scores in the Observing subscale can predict lower scores in the VAS. Moreover, higher scores in the Describing subscale predict higher scores in VAS, CSQ-CAT and TSK-17; higher scores in Acting with Awareness predict lower scores in VAS and CSQ-CAT; higher scores in Non-judging predict lower scores in VAS, RMDQ-24 and TSK-17; finally, higher scores in Non-reactivity predict higher scores in RMDQ-24 and TSK-17. conclusions All factors existing in mindfulness are associated to MSP after controlling for certain undesirable outcomes. It seems that mindfulness interventions can potentially result in clinical improvement of patients suffering from chronic musculoskeletal pain.
