Personal construct theory

Personal construct theory or personal construct psychology (PCP) is a theory of personality and cognition developed by the American psychologist George Kelly in the 1950s. From the theory, Kelly derived a psychotherapy approach and also a technique called the repertory grid interview that helped his patients to analyze their own constructs (schemas or ways of seeing the world) with minimal intervention or interpretation by the therapist. The repertory grid was later adapted for various uses within organizations, including decision-making and interpretation of other people's world-views.
