Italian version of the Waddell Disability Index for chronic low back pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective observational project uses a standardized cross-cultural translation process (forward and backward translations) and expert clinician panel review, followed by pilot testing to produce a consensus Italian version (WDI-I). The finalized WDI-I will be given to 115 adults with low back pain lasting at least three months at two rehabilitation centers, together with measures such as the Numeric Pain Rating Scale and the Italian Oswestry Disability Index. Psychometric validation will examine reliability (including internal consistency and test-retest) and validity (including convergent and construct validity) of the WDI-I. Results will determine whether the WDI-I is appropriate for routine clinical and rehabilitation use in Italian-speaking patients.
