Editing Personal construct theory (section)

== Therapy approach ==
Kelly believed in a non-invasive or non-directive approach to [[psychotherapy]]. Rather than having the therapist interpret the person's [[Psyche (psychology)|psyche]], which would amount to imposing the doctor's constructs on the patient, the therapist should just act as a facilitator of the patient finding their own constructs. The patient's behavior is then mainly explained as ways to selectively observe the world, act upon it and update the construct system in such a way as to increase predictability. To help the patient find their constructs, Kelly developed the repertory grid interview technique.

Kelly explicitly stated that each individual's task in understanding their personal psychology is to put in order the facts of their own experience. Then the individual, like the scientist, is to test the accuracy of that constructed knowledge by performing those actions the constructs suggest. If the results of their actions are in line with what the knowledge predicted, then they have done a good job of finding the order in their personal experience. If not, then they can modify the construct: their interpretations or their predictions or both. This method of discovering and correcting constructs is roughly analogous to the general [[scientific method]] that is applied in various ways by modern sciences to discover truths about the universe.
