The questionnaire was translated in

The questionnaire was translated into Hebrew by the
investigator with the assistance of the FACIT organization,
according to the instructions of the organization.
A pilot study of 15 patients was conducted with the
Hebrew translation. Results of the pilot study showed
high reliability (Cronbach a = 0.92) for the Hebrew version.
Therefore, no changes were made to the Hebrew
version of the FACT-ES questionnaire.
