Rasch analysis resulted in an improved Norwegian version of the Pain Attitudes and Beliefs Scale (PABS)

Conclusions Rasch analysis produced an improved Norwegian version of the PABS which represents true (fundamental) measurement of clinicians’ biomedical and biopsychosocial treatment orientation. However, researchers should be aware of the low discriminative ability of the biopsychosocial subscale when analyzing differences and effect changes. Implications The study presents a revised PABS that provides interval-level measurement of clinicians’ pain beliefs. The revision allows for confident use of parametric statistical analysis. Further examination of discriminative validity is required.
