Repertory Grid Technique as an assessment instrument for case formulation

Abstract

This paper begins with a presentation of the Repertory Grid Technique (RGT) within the framework of Personal Construct Theory. It follows with the description of the administration of a grid to Ana, a client diagnosed with major depressive disorder, bulimia nervosa, and avoidant personality disorder, as well as of other symptoms. This case is selected to illustrate the use of the RGT because of both its clinical complexity and the way in which her cognitive structure(as depicted by the RGT) is reflected in the presenting symptoms. Despite the fact that Ana eagerly requested help, during the therapy sessions she seems to be reluctant to talk about herself. The RGT proved to be a useful way of approaching her world view, and also a powerful instrument for case formulation.
