IPIP CPI Proxy Inventory (313-item)

This 313-item inventory is an IPIP-style public-domain proxy for constructs similar to those measured by the California Psychological Inventory. It is not the proprietary CPI, CPI 434, or CPI 260 form. Items use a general/typical personality timeframe and a five-point agreement scale.
