Text: We do not believe it would be ethical to make our data publicly available. We interviewed a small but exhaustive sample of major national stakeholders in the Zimbabwean mental health system. Given the limited number of people who work in this space, we need to be particularly cautious to protect their identities, as promised in their informed consent. The qualitative nature of in-depth transcript data exhibits nuance, tone, and other contextual signifiers that, even after redaction, could lead a reader to identify the interviewee. Data requests may be sent to the corresponding author, Helen Jack, whose email address is helen_jack@hms.harvard.edu.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
