This dataset contains aggregate coding results from a six-month review of Reddit discussions concerning oral and sublingual ketamine therapy. The public dataset includes aggregate counts, coding categories, codebook materials, methodology notes, and data-release controls. It does not include Reddit usernames, post URLs, direct quotations, raw Reddit text, post-level records, or coder notes from individual posts. The dataset is intended to support the accompanying white paper on patient-reported themes in online discussions of oral and sublingual ketamine therapy. Because the underlying source material concerns health-related discussions from Reddit, the public dataset has been aggregated and de-identified to reduce traceability and avoid redistribution of post-level Reddit-derived records.
