AB  - The Pain Catastrophizing Scale (PCS) is a widely studied tool to assess pain 
      catastrophizing for chronic low back pain (LBP). Short forms of the PCS exist, 
      but their measurement precision at individual level is unclear. This study aimed 
      to analyze the Rasch psychometric characteristics of the PCS and three of its 
      short forms (two 4-item and one 6-item) in a sample of 180 Italian-speaking 
      patients with chronic LBP, and compare their measurement precision at the 
      individual level. We performed a Rasch analysis on each version of the PCS and 
      calculated test information functions (TIFs) to examine conditional measurement 
      precision. Rasch analysis showed appropriate rating category functioning, 
      unidimensionality, and acceptable fit to the Rasch model for all PCS versions. 
      This represented a prerequisite for performing further advanced psychometric 
      analyses. According to TIFs, the PCS full scale showed-at any score level-higher 
      measurement precision in estimating individual pain catastrophizing than its 
      short forms (which had unacceptably high standard errors of measurement). Our 
      results show acceptable conditional precision of the PCS full scale in estimating 
      pain catastrophizing. However, further studies are needed to confirm its 
      diagnostic accuracy at individual level. On the other hand, the study warns 
      against use of the three PCS short forms for clinical decision-making at the 
      individual level.
