Transcultural Validation of the French Version of the " Patients' Endorsement of a Biopsychosocial Model of Chronic Pain " Scale

Transcultural Validation of the French Version of the " Patients' Endorsement of a Biopsychosocial Model of Chronic Pain " Scale

We will validate the French version of the "Patients' Endorsement of a Biopsychosocial model of chronic pain (PEB) scale" by comparing it to the "pain self-efficacy" questionnaire

The primary objective is to validate the French version of the PEB scale, called "Echelle d'Adhésion du modèle Bio-psycho-social par des patients avec Douleur Chronique ABDC".

The hypothesis is that the ABDC scale is a valid measurement tool to measure and operationalize beliefs about the biopsychosocial nature of pain in adults with chronic pain.

Consenting patients will receive paper copies of the study questionnaire including the questionnaires named in the secondary outcomes section, except those which are already included in the standard evaluation questionnaire of the pain consultation (BPI, GAD-7, PHQ-9). Patients will return the questionnaire either at a the same or a follow-up consultation, or send in the questionnaire by post in a prepaid envelope.

Inclusion Criteria:

• - Patients with chronic pain (defined by ICD-11 as pain persisting or recurring longer than 3 months) having a chronic pain consultation at the HUG
• French-speaking and able to understand the study information
• ≥18 years of age

Exclusion Criteria:

• - Inability to understand the consent form and the questionnaire, e.g. due to lan-guage problems, psychological disorders, dementia, etc. of the participant
• Enrolment of the investigator, his/her family members, employees and other de-pendent persons
