The patient must be able to complete the study questionnaires in English because the standardized questionnaires are only validated in English. If the patient requires a translator, they should be excluded from the study. Otherwise, you should assess the patient’s language comprehension skills as you speak with them. If you believe the patient can communicate effectively in both spoken and written English and is able to complete questionnaires independently, they are eligible and should be included in the trial. The recruiting physician may also inform you of the patient’s English proficiency based on their interaction with the patient during the clinical exam. It should be recorded in the screening log if a patient does not have adequate English proficiency, as this is an exclusion criterion.
