Research rating fidelity

The manuals converge on the need for standardised, reliable measurement. Across the extracts, the shared emphasis is on consistent administration of clinical ratings, careful timing, and methods that reduce measurement error so efficacy and safety endpoints can be interpreted with confidence. They also agree that rater competence matters, whether through trained assessors, supervision, or independent verification. The manuals differ in how they frame that reliability. The ketamine protocol focuses most directly on research rating fidelity, with trained research assistants, inter-rater reliability checks, supervision by the principal investigator, and repeated symptom, craving, withdrawal, and safety ratings at specified time points. The GH001 trial places more emphasis on remote psychiatric outcome assessment, including the rater being independent of dosing and direct care, and on applying consistent recall periods after dosing. The ibogaine study shifts the emphasis towards research-grade measurement reliability in physiologic as well as clinical data, especially careful QT interval measurement, ideally with trained raters and independent verification, alongside validated plasma quantification methods where relevant. So the overlap is in standardisation and reliability, while the main difference is whether the manual foregrounds psychiatric ratings, remote assessment, or physiologic measurement precision.
