The elaboration of personal construct psychology.

More than half a century has passed since the publication of George Kelly's (1955/1991) The Psychology of Personal Constructs. This review considers the elaboration of personal construct psychology (PCP) during this time, both by Kelly and by others who developed his ideas. Advances to the theory have principally concerned implicative relationships between constructs, construing of the self, social relationships, emotions, links with other approaches, and supporting research. With regard to methods of assessment of construing, major developments have occurred in both repertory grid and nongrid techniques, such as laddering. The principal advances in the applications of PCP have been in the clinical, educational, and organizational fields, but have by no means been limited to these areas. It can be concluded that PCP has met Kelly's own design specifications for a useful theory and that PCP can perhaps anticipate at least another half-century of elaboration.
