Table 1 Operationalization of response shift for DH in the CRT model

From: Using classification and regression tree modelling to investigate response shift patterns in dentine hypersensitivity

Response shift Operationalization Qualitative indicator Interpretation
Recalibration Changes in subscale scores over time ↓DHEQ scores with worse DH Downward shift At follow up individuals experience clinical signs of DH but DHEQ total score is lower than at screening
  ↑ DHEQ scores with less DH Upwards shift At follow up individuals experience no clinical signs of DH but DHEQ total score is higher than at screening
  ↑ DHEQ scores with worse DH No recalibration At follow up individuals experience clinical signs of DH and DHEQ total score is higher than at screening
Reprioritization Changes in the relative importance of each subscale to the model over time
