Changes in pain catastrophizing |
Changes in pain catastrophizing were assessed with the pain catastrophizing scale. It consists of a 13-item scale with values from 0 to 4. The higher the score, the greater the pain catastrophization. |

Changes in pain interference |
In the PROMIS PI, item category responses range from 1 to 5. T scores had a mean score of 50 and a standard deviation of 10 points. Low scores on the PROMIS PI represent less interference of pain with physical function, whereas high scores represent greater interference with physical function. |

Changes in the sensory, affective and evaluative dimensions of pain. |
The Short Form McGuill Pain Questionnaire (SF-MPQ) is a version of the original McGuill Pain Questionnaire, discovered by Melzak in 1987. This scale is divided into several parts. The first part consists of a list of 15 adjectives, including 11 sensory and 4 affective descriptors of pain (e.g., terrible, throbbing, etc.) on a scale ranging from 0 (none) to 3 (severe), giving an overall score ranging from 0 to 45, as well as two scores from 0 to 33 for the sensory subscale and 0 to 12 for the affective subscale. In addition, it includes a VAS scale that assesses the patient's pain in the last week. Finally, it includes a Present Pain Intensity Scale (PPI). The PPI is based on a single item measuring overall pain intensity. Patients are asked about their current level of pain on a 5-point Likert scale ranging from 0 (no pain) to 5 (unbearable). This scale has been shown to have excellent psychometric properties. |
