Language validation
All of the survey statements and questions were initially created in English. They were then translated into Bahasa Indonesia by the first author and presented to participants based on their language preference. Participants’ responses written in Bahasa Indonesia were also translated into English to enable analysis and discussion between the project investigators. All questionnaires and a quarter of the free-text responses were also back-translated into English and were reviewed by another two native Indonesian speakers to ensure the translation validation.
