Personal Construct Psychology

People anticipate events through a personal system of bipolar constructs, distress arises when that system fails to make experience predictable, and therapy consists in helping the person elaborate, test and revise their constructs.

1955 – presentPCPEvidence: Limited evidence
The claim, in one line

Every person is a scientist, testing personal theories about the world. Some theories are not being tested.

Who built it

  • George A. Kelly

    1905–1967

    Psychologist, Ohio State

    Published a complete, formally stated theory of personality and therapy in 1955, decades ahead of the constructivist turn. The repertory grid remains a genuinely original assessment method.

Theory of personality

Kelly’s fundamental postulate: a person’s processes are psychologically channelised by the ways in which they anticipate events. We are not driven by drives or shaped by reinforcement; we are in the business of prediction, and we construct personal theories to do it.

Constructs are bipolar — meaning is created by contrast, and knowing what someone means by "strong" requires knowing what they oppose it to. For one person the contrast is "weak"; for another it is "gentle", which is an entirely different construct with entirely different implications.

Constructive alternativism
Kelly’s core philosophical position: no event has only one possible interpretation, and any construction can be replaced by a better one.
Core constructs
Those governing identity and existence. Threat is the awareness of imminent comprehensive change in them.
Anxiety
The awareness that events lie outside the range of one’s construct system — not fear of something, but the absence of any way to construe it.
Hostility
Continuing to extort confirmation for a prediction that has already failed.
Guilt
Awareness of dislodgement from one’s core role structure — behaving in a way inconsistent with who one takes oneself to be.

Theory of psychopathology

Disorder is the repeated use of a construction despite consistent invalidation. The person is a scientist who has stopped running experiments — either because the outcome is too threatening, or because their system has no alternative available.

Theory of change

  1. 1Elicit the construct system, usually with a repertory grid or laddering.
  2. 2Identify where the system fails to predict, and where it is being held rigid.
  3. 3Loosen construing where it is over-tight; tighten it where it is too loose.
  4. 4Elaborate alternatives — new constructs, or new ways of applying existing ones.
  5. 5Test them behaviourally, in the world.

Key concepts

The vocabulary you need to read the literature and to be understood in supervision.

Where it sits in the transtheoretical grid

Which change processes the system leans on, and at what level of content it aims.

Change processes emphasised
  • Consciousness raising

    Increasing information about oneself and the problem - feedback, interpretation, education, observation.

  • Self-reevaluation

    Appraising how one thinks and feels about oneself with respect to the problem; values clarification.

  • Self-liberation (choosing)

    Choosing and committing to act, plus the belief that one can change - the deliberate exercise of agency.

  • Counterconditioning

    Substituting an incompatible response for the problem response - relaxation, assertion, exposure, defusion, opposite action.

Content levels targeted
  • Maladaptive cognitions
  • Intrapersonal conflicts

Before you begin

What Praxical.Psych is, and is not

Praxical.Psych is an educational tool. It teaches the theory, evidence base and clinical method of psychotherapy at the level of an advanced survey course, and it lets you rehearse a complete session in a simulator.

It is not medical, clinical, psychological or legal advice. It cannot diagnose or treat anyone, and it does not state the law where you practise — requirements differ by jurisdiction and change. Nothing here creates a clinician–patient or solicitor–client relationship.

  • Every patient, transcript and case in this app is fictional — a composite written for teaching. None depicts a real person.
  • Praxical.Psych is not therapy, not a substitute for supervision, and not a credential. Competence to practise comes from training, supervised hours and licensure.
  • Scores from the instruments here are for learning how they behave. They are not a diagnosis and not a risk assessment, and must not inform a decision about a real person.
  • Do not enter real patient information. Everything you type stays in this browser, but that is not the same as a compliant clinical record system.
If you are in crisis
