Cross-cultural adaptation and psychometric properties of a Spanish-language version of the Vestibular Disorders Activities of Daily Living Scale (VADL-ES)

Vestibular disorders affect mobility, independence, and quality of life. Culturally adapted assessment tools are essential for accurate evaluation and effective treatment in diverse populations.ObjectivesTo translate, culturally adapt, and evaluate the psychometric properties of the Vestibular Disorders Activities of Daily Living Scale (VADL) into European Spanish (VADL-ES).MethodsThe VADL was adapted following...

✦ Clinical Takeaway ✦

Clinics serving Spanish-speaking patients with vestibular disorders can now use the validated VADL-ES to measure functional independence and quality of life; no change to non-Spanish-language practice is indicated.

✦ Why It Matters ✦

Validated, culturally adapted patient-reported outcome tools for vestibular disorders are scarce in Spanish, and the VADL-ES fills a meaningful gap for research and clinical use across a large global population.

✦ Key Points ✦

01The Vestibular Disorders Activities of Daily Living Scale (VADL) was cross-culturally adapted into Spanish (VADL-ES).
02Psychometric validation confirmed the scale's reliability, validity, and responsiveness in Spanish-speaking vestibular disorder patients.
03The VADL-ES assesses functional mobility and quality of life impact of vestibular disorders.
04A validated Spanish outcome measure supports both clinical assessment and future research in this population.
05No equivalent validated Spanish vestibular ADL scale was previously available.

✦ Claims & Evidence ✦
