This research examines and reframes the long-standing pursuit of validation in personality research, in response to a shift in the field to focus on inter-individual idiographic contexts and constructs by focusing on Know- ledge-and-Appraisals Personality Architecture (KAPA) as a method for person-centred, non-trait-based personality research. Aspects of instrument validity and validation are addressed, exploring relationships of cognition with self-variables to support the unique and informative nature of KAPA model for measuring personality architecture. First the validity of two empirical questionnaires, Self-efficacy for Performing (SEP) and the Metacognitive Thinking Questionnaire (MTQ) are demonstrated through EFA and CFA. Then the KAPA model for personality architecture, a person-based method that sits outside the traditional questionnaire approach to measuring personality, is validated by using elements of traditional validation and through exploring theoretically expected ontological relationships.
