title: [Measures of success in treatment of chronic back pain: pain intensity, disability and functional capacity: determinants of treatment success in multimodal day clinic setting].
abstract: BACKGROUND
  The empirical findings on risk factors for a favorable/unfavorable outcome upraised via pain intensity, disability and functional capacity after empirically well-evaluated multimodal treatment are inconsistent. The objective of this study was to analyze the relevance of psychosocial and pain-related variables for therapeutic outcome in an unselected sample of patients with chronic non-specific back pain (CBP).
  
  
  METHODS
  Included were 681 patients with CBP referred to an outpatient-based multidisciplinary pain rehabilitation program and 320 took part in a survey 12 months later. Before, directly after and 12 months after the program the patients received a questionnaire which contained pain-related items on pain intensity, disability, self-reported functional capacity which were defined as outcome variables, psychological items (anxiety, depression) and work-related items which represented probable predictor variables. Multivariable regression analyses were calculated to estimate the contribution of the selected parameters on pain intensity, disability and functional capacity.
  
  
  RESULTS
  The calculated regressions showed only a moderate ability to predict or explain the outcomes pain intensity, disability and functional capacity. However, depression and body mass index (BMI) were significantly related to pain-related therapeutic outcome.
