DMH Intervention Program and High-Intensity Therapist Assistance
Participants who were stepped up to the high-intensity therapist-assisted treatment condition also completed the same Life Flex program augmented with 50 minutes per week of video chat support for 7 weeks with a therapist for individualized tailoring of the program, questionnaire feedback, and discussion of module content (ie, examination of unhelpful cognitions and support in completing exposure tasks or behavioral activation), as well as skill generalizability beyond the Life Flex program. Similar to the low-intensity condition, therapists were encouraged to be supportive and manage any issues of risk.The therapist assistance in both treatment conditions was manualized via case note templates, which included session agendas used by the therapists. In all 3 treatment conditions, participants had access to the Life Flex program for a further 14 weeks after the last module release.
