FRIEND · 01- Pre-Registration

Pre-registration record for the FRIEND feasibility RCT (de Blauwe & Fidalgo, 2026, University of East London). Holds the original AsPredicted submission (#265934, locked prior to data collection) and the deviation log documenting every protocol change made between pre-registration and final analysis. The deviation log follows the Willroth & Atherton (2024) format: each deviation classified by domain, severity, reason, and timing relative to data collection, and feeds the pre-registration audit recorded in 01g (Analytical Decisions Log). FRIEND piloted the DESI-12 proof-of-concept measure (the seed of the DESI lineage); see 01g for the broader protocol-evolution record. Maintainer: V. J. de Blauwe (ORCID 0009-0004-8975-6249).
