The Italian version of the Brain Injury Rehabilitation Trust (BIRT) personality questionnaires: five new measures of personality change after acquired brain injury.

The aim of this study was to describe the translation and adaptation of the BIRT personality questionnaires for the Italian population. This included the replication of validity testing and the collection of normative data. Following translation and adaptation according to cross-cultural guidelines, the questionnaires were administered as a pre-test to a sample of 20 healthy subjects and then to 10 patients. The questionnaires were then administered to 120 healthy subjects equally distributed by sex, education, and age, to collect normative data from an Italian population. The questionnaires were easily administered to both healthy subjects and patients. Statistical analysis on normative data was conducted to find the mean value for each questionnaire. This study lays the foundations for using a new instrument to assess behavioral changes after acquired brain injury on the Italian population.
