The Pain Sensitivity Questionnaire (PSQ) is a tool created in 2009 by Dr. R. Ruscheweyh in Germany. It aims at identifying the natural sensitivity to pain, through a set of 17 simple questions. These questions simulate daily life situations likely to induce pain of various intensities. The internal validity of the tool had been demonstrated both for the original version in German, and then for its English version. The external validity had also been demonstrated by correlation to real nociceptive stimulations applied to healthy volunteers (German version), and to patients before surgery (English version). A French validation of the questionnaire is needed, in order to integrate it in pain research programs in French-speaking countries.
The aim is to validate the French version of the PSQ in a 2-step plan : (i) validity of internal structure, convergent validity and reproducibility, in a sample of patients before scheduled surgery, and (ii) structure and convergent validity against external criterion, in healthy volunteers. A secondary objective is to study the relationship of scores of the PSQ with a scale assessing sensitivity to natural smells, noise and light sensitivity.
