The FFPI-C: Five-Factor Personality Inventory — Children is a standardized, norm-referenced self-report inventory designed to measure personality traits and dispositions in children and adolescents, as well as adults. It was normed on a representative sample of 1,284 individuals. It is based on a modern five-factor personality theory, which concludes that five broad factors account for the majority of variance in the personality descriptors. Mental health professionals or researchers studying child and adolescent personality can use it. The inventory can be self-, individually-, or group-administered by any professional with psychological and personality assessment experience.
