Structural relationship of behavioral activation and inhibition system, dispositional mindfulness and chronic pain

There is evidence of a relationship between mind and body about pain. The aim of this study was to study the structural relations among chronic pain, mindfulness and behavioral activation and inhibition systems.
The present research is descriptive-correlative, retrospective, and cross-sectional.In this research from 300 students, 166 students with chronic pain from the Payam-E-Noor University of Tehran were selected by voluntary and available sampling. McGill pain questionnaire, and five-facet mindfulness scale and behavioral activation and inhibition systems scale were used as research tools for data collection.Data were analyzed using correlation and structural equation.
The results showed that the hypothesized model fit is good and acceptable. Behavioral Activation System has a direct and negative effect on pain) β=0/38) and behavioral inhibition system direct and positive effect on pain) β=0/36). The Behavioral Activation System through the mediation of mindfulness has an indirect effect on pain and behavioral inhibition system through mindfulness has an indirect effect on pain.
It can be concluded that behavioral activation and inhibition systems and mindfulness important determinants of pain.
