AB - BACKGROUND: The Fear-Avoidance Beliefs Questionnaire (FABQ) is a widely used
outcome measure. There is still a lack of information concerning responsiveness
and minimal clinically important difference (MCID), limiting its use for clinical
and research purposes. AIM: The aim of this study was to examine reliability,
responsiveness and MCID of the two FABQ scales in subjects with chronic low back
pain. DESIGN: Methodological research based on a prospective single-group
observational study. SETTING: Outpatient, Unit of rehabilitation. POPULATION:
Chronic non-specific low back pain. METHODS: At the beginning and the end of a
multidisciplinary program (8-week), 129 subjects completed the FABQ scales.
Reliability was determined as internal consistency (Cronbach's alpha) and
test-retest reliability (96-hour interval; N.=64; Interclass correlation
coefficient [ICC 2.1]). Responsiveness was calculated both by distribution-based
and anchor-based methods, using as external criterion the Global Perceived Effect
Scale (GPE: 7 levels), rated by each individual. RESULTS: Cronbach's alpha and
ICC(2,1) were respectively: 0.75 and 0.90 for FABQ-Physical Activity
Scale (FABQ-PA), and 0.85 and 0.95 for FABQ-Work Scale (FABQ-W). Minimum
detectable change (MDC95) values were 3.69 points for FABQ-PA, and
5.95 points for FABQ-W. In receiver-operating characteristic curves, splitting
GPE data into null/minimal/moderate improvement vs. large improvement (GPE 0-2
vs. GPE 3): 1) for FABQ-PA, the area under the curve (AUC) was 0.97 and the best
cutoff score identifying meaningful change in fear-avoidance beliefs about
physical activity was a change of 4 points; 2) for FABQ-W, the AUC was 0.97 and
the best cutoff score for meaningful change in fear-avoidance beliefs about work
activities was a change of 7 points. CONCLUSIONS: After triangulation of the
above results, a change of 4 points for FABQ-PA and 7 points for FABQ-W were
selected as MCID. These two values represent cutoffs that seem to accurately
identify meaningful change in fear-avoidance beliefs, according to subject's
judgement. CLINICAL REHABILITATION IMPACT: 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.
