title: Clinical and social predictors of application for social security disability insurance by workers' compensation claimants with low back pain.
abstract: OBJECTIVE
  The objective of this study was to identify clinical and social predictors of application for Social Security Disability Insurance (SSDI) in workers' compensation claimants with low back pain.
  
  
  METHODS
  Archival and interview data were analyzed for 1372 Missouri claimants who were, on average, nearly 42 months postinjury.
  
  
  RESULTS
  Two hundred sixty-five (19.3%) claimants were receiving SSDI (8.0%) or had applied for SSDI (11.3%). Logistic regression indicated that black race, older age, herniated disc diagnosis, surgery, and longer time since injury were associated with increased odds of SSDI. Higher preinjury wage, more education, and higher satisfaction with medical treatment and/or treatment by employer were associated with decreased odds of SSDI.
  
  
  CONCLUSIONS
  Application for SSDI among claimants with occupational low back pain is associated with social factors like race, satisfaction, and socioeconomics as well as clinical factors like diagnosis and surgery.
