Poor Prognosis in a Case of Depression as Predicted by the Repertory Grid

In Personal Construct Theory (Kelly, 1955), a person is considered to describe and predict his perception of the world by using bi-polar constructs which form an integrated system. In clinical practice it is possible to elicit from a patient not only a description of his environment in his own constructs but also an account of how he uses his construct system to predict future events. The following study shows how an assessment of the patient's construct system is useful in evaluating the outcome by therapy.
