Reliability, responsiveness and minimal clinically important difference of the two Fear Avoidance and Beliefs Questionnaire scales in Italian subjects with chronic low back pain undergoing multidisciplinary rehabilitation

Abstract

The present study calculated - in a sample of people with chronic low back pain - the minimal clinically important change of the two FABQ scales (FABQ-Physical Activity Scale and FABQ-Work Scale). These values increase confidence in interpreting score changes, thus enhancing their meaningful use in both research and clinical contexts.
