SPDQ, Spine painDETECT questionnaire; SF-SPDQ, short-form SPDQ; PD-Q, painDETECT questionnaire.
*Gradation of each of the seven types of pain is answered with one of the following responses: never = 0; hardly noticed = 1; slightly = 2; moderately = 3; strongly = 4; very strongly = 5. The two questions shaded in gray are the items of the SF-SPDQ.
To calculate the SPDQ total score, an item score of each SPDQ item, calculated by a PD-Q score multiplied by the weighting coefficient for the item, is added up for all nine items, after which a constant value of 12 is subtracted from it.
To calculate the SF-SPDQ total score, an item score of each SF-SPDQ item, calculated by a PD-Q score multiplied by the weighting coefficient for the item, is added up for the two items, after which a constant value of 7 is subtracted from it.
The cutoff score for the possible spinal neuropathic pain in the SPDQ and SF-SPDQ is ≥0.
