Consistent evidence was found for the predictive value of pain intensity ( more pain-- > worse outcome ) , several work-related parameters ( e.g. , high satisfaction-- > better outcome ) , and coping style ( less active coping-- > better outcome ) .

No consistent evidence was found for other psychological variables .

OBJECTIVE To determine predictors of outcome of multidisciplinary rehabilitation-or back school treatment  for patients with chronic low back pain .
SUMMARY OF BACKGROUND DATA Numerous review s have been performed to gain insight into which patients benefit from which treatment .
However , no review has systematic ally focused on predictors from multiple domains ( i.e. , sociodemographic , physical , and psychological ) , or on treatment outcome measured as activity limitation or participation restriction .
Psychometric properties of the Multidimensional Pain Inventory, Dutch language version (MPI-DLV).
The purpose of this study was to investigate the psychometric properties of a Dutch translation of the Multidimensional Pain Inventory , MPI-DLV . Data was available on 733 chronic pain patients . There were three issues of special interest . The first one related to the comparability between the MPI-DLV and the American and German MPI versions with regard to the psychometric aspects . The second dealt with the construct validity of the  MPI-DLV scale ' general activity ' . It was predicted that patients with high scores on this scale would be in better physical condition , as measured on a working-to-tolerance bicycle ergometer test . In relation to the third issue , attention was given to the factor-invariance between fibromyalgia patients and back pain patients . From the results obtained it was concluded that ( 1 ) the factorial structure of the three MPI parts is replicated and the reliability estimates and validity indicators are similar to those from the American and German versions ; ( 2 ) patients with high scores on the ' general activity ' scale are in better physical condition and ( 3 ) MPI-DLVs of fibromyalgia and back pain patients do have similar factorial structures . Evidence was also obtained that the  MPI-DLV  is sensitive to treatment changes . Applications of the MPI-DLV are discussed
