Outcome measurement in a personalized, AI-generated digital wellness intervention: an observational protocol using the PHQ-8 and GAD-7
Year: 2026
Type: preprint
Study design: Study Protocol
Abstract: This registration documents, in advance of any qualifying cohort accumulating, the observational outcome-measurement protocol for a personalized, AI-generated hypnosis and guided-meditation application addressing sleep, stress, anxiety and habit change. The application administers the PHQ-8 (depression) and GAD-7 (generalized anxiety) at baseline and on a 14-day re-administration cycle, without modification to item wording or response scale. The PHQ-8 is used rather than the PHQ-9 because the platform employs no clinicians and operates no crisis service, so a suicidal-ideation disclosure made through the application would reach no one qualified to act on it; crisis resources are instead made permanently available without an account. The full methodology is published at DOI 10.5281/zenodo.22086938. No outcome data are reported at the time of registration.
