Minimal important difference of the 12-item World Health Organization Disability Assessment Schedule (WHODAS) 2.0 in persons with chronic low back pain

ConclusionsUsing an anchor-based approach, the MID of WHODAS-12 is estimated at -3.22 (95%  CI -4.79 to -1.64) or -5.99 (95% CI − 7.20 to -4.79) in adults with chronic LBP. These MID values inform the utility of WHODAS-12 in measuring functioning to determine whether rehabilitation or other health services achieve a minimal difference that is meaningful to patients with chronic LBP.
