The web-based questionnaire was created using electronic forms on the DMH website. The web-based questionnaire and associated participant flow were tested for functionality via the creation of dummy participants before the trial commenced. Participants were required to complete the preintervention and week 3 during-the-intervention questionnaires to gain access to the Life Flex program.
