Short personality tests: Big Five Inventory (BFI-10) vs BFI-44 — 23% loss, keep full

BFI-10 loses about 23% test-retest reliability versus BFI-44; BFI-44's extra items improve reliability and facets. Default to BFI-44 for actionable decisions.

Abstract

BFI-10 loses about 23% test-retest reliability versus BFI-44; BFI-44's extra items improve reliability and facets. Default to BFI-44 for actionable decisions. Independent technical note mirroring the canonical version: https://psychprofile.io/blog/short-personality-tests-big-five-inventory-bfi-10-vs-bfi-44-23-loss-keep-full.php
