Psychosocial resources and chronic pain in individuals with spinal cord injury: evidence from the second Swiss national community survey

Study design Cross-sectional. Objective To investigate the associations of a set of psychosocial resources with pain and pain-related factors in individuals with spinal cord injury (SCI) and chronic pain. Setting Community, Switzerland. Methods Data from 1,064 individuals with chronic pain who participated in the second community survey of the Swiss Spinal Cord Injury Cohort Study (Survey 2017) were analyzed. Multiple linear regression modeling was performed to test the hypotheses that higher levels of psychosocial resources (self-efficacy, self-esteem, purpose in life, optimism, hope, social support, sense of belonging) are negatively associated with pain intensity, pain interference and depressive symptoms. Results Higher self-esteem, optimism and hope were related to less pain interference and all psychosocial resources under study were negatively associated with depressive symptoms in final models. However, neither of the psychosocial resources was related to pain intensity when models were adjusted for pain interference and depressive symptoms. Conclusions These findings strengthen the evidence that psychosocial resources can have an impact on pain interference and depressive symptoms as pain-related factors, and support the notion that psychosocial resources might be promising targets for pain interventions in individuals with SCI.
