Abstract
Objectives
To translate and culturally adapt the Avoidance–Endurance Questionnaire (AEQ) into Danish, assessing both fear avoidance responses (FARs) and endurance responses (ERs), while investigating relevant psychometric properties.
Methods
Panel 1 translated AEQ using the dual-panel method. Panel 2 evaluated the translation and face validity assessed by interviewing both panels. The questionnaire was administered to 119 chronic pain patients, and their responses were used to assess factor structure and internal consistency. Of these, 90 of the participants completed the questionnaire again, and their responses were used to evaluate test–retest reliability.
Results
Both patients and clinicians assessed DK-AEQ with good face validity. Confirmatory factor analysis showed adequate to good fit for affective and cognitive subscales, while adequate to poor fit for behavioral subscales. The internal consistency was adequate in subscales of FAR (Cronbach´s α = 0.8–0.9) and ER (Cronbach’s α = 0.7–0.9). An excellent test–retest reliability was found for FAR 0.94 (95%, CI: 0.91–0.96) and ER 0.92 (95%, CI: 0.88–0.95).
Discussion
The Danish version of the AEQ is a valid and reliable tool for assessing FAR and ER in people with chronic pain. It provides clinicians with valuable information on the affective, cognitive, and behavioral mechanisms underlying pain behavior, which can support therapeutic dialog. Potentially, implementing the DK-AEQ may enable stratification of management strategies for individuals living with chronic pain in Denmark.
