Validated Translations Outcome Instruments

As part of WP10 of the CENTER-TBI project, translations of outcome assessments have been undertaken for up to 20 languages.

When translations of assessments were not available, the material originally in English was translated into local languages of the countries who participated in the CENTER-TBI study using a process of linguistic validation based on good practice (v. Steinbuechel et al, 2021). Native speakers, predominantly experts in the field of TBI, were asked to perform forward and backward translations as well as harmonization of the translations. Cognitive debriefings – where possible – were carried out with a sample of lay individuals and/or individuals after TBI. A team of international researchers and CENTER-TBI collaborators refined the translations in national and international harmonization rounds until consensus was reached.

Material for the Rey Auditory Verbal Learning Task (RAVLT) was primarily generated using linguistically and culturally adapted translations of the source lists with the aim of retaining characteristics such as the familiarity, concreteness and imageability of words. Word frequency was checked using available corpora.

Where the language sample sizes in the CENTER-TBI database were sufficient, psychometric validation of the patient-reported outcome instruments was carried out. Other information on studies concerning the psychometric properties of individual assessments can be found in the CENTER-TBI publication list.
