ABSTRACT NUMBER: ESOC2026A1073 AN INTERNATIONAL TRANSLATION PROCESS FOR VISUAL IMPAIRMENT SCREENING AND QUESTIONNAIRE RESOURCES IN ADULT BRAIN INJURY

Abstract Background and aims Visual impairment caused by stroke is common. New onset visual impairment occurs in about 60% of stroke survivors with prevalence of visual impairment in about three quarters of stroke survivors. The Visual Impairment Screening Assessment (VISA) vision screening tool is a validated tool used by stroke clinicians to detect visual impairment in stroke survivors. The Brain Injury-related Visual Impairment Impact Questionnaire (BIVI-IQ) is a validated quality of life instrument. VISA and BIVI-IQ were developed and validated using the English language in the UK. The aim of this study was to undertake a translation process into further languages with international collaborators. Methods We followed the World Health Organisation translation process. Implementation of this process includes the following steps: 1) Forward translation; 2) Expert panel Back-translation; 3) Pre-testing and cognitive interviewing; and 4) Final version production. Native-language translation was made through collaboration with international clinicians in ophthalmology, neurology and orthoptic professions. Results VISA and BIVI-IQ were successfully translated, checked and fully discussed for content and context, and are now available in 35 languages. Full validation studies are available for English, Norwegian and Dutch languages, and underway for Chinese, Romanian and Italian. Conclusions VISA and BIVI-IQ are available for free download for use internationally in the clinical assessment of brain-injury patients (www.vision-research.co.uk). Implementation of VISA in other countries has shown it to have validity for international use in clinical and research practice. Further international dissemination and validated is encouraged.
