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.
