Abstract

Objective: To explore the factor structure of the European Brain Injury Questionnaire and to assess the cross-cultural and construct validity of this questionnaire by using Rasch analysis.

Participants: A total of 366 individuals with traumatic brain injury or stroke were recruited from 3 different countries: Spain (116 participants), the United Kingdom (110 participants), and France (140 participants).

Analyses: We first performed a factor analysis and then applied Rasch analysis to the resulting factors to examine construct and cross-cultural validity.

Results: Three subscales labeled Depressive Mood, Cognitive Dysfunction, and Poor Social and Emotional Self-regulation were extracted using the factor analysis. In the Rasch analyses, 8 items were removed because of misfit and 7 items showed differential item functioning by country.

Conclusion: Rasch analyses showed good fit to the model, unidimensionality, construct validity, and good reliability of the 3 European Brain Injury Questionnaire subscales. However, only the Depressive and Cognitive subscales showed cross-cultural validity.
